Zero point of work-piece is set at the origin point of ABS coordinate. The relative distance between datum of ABS and SDM remains unchanged when ABS datum is changed.

1. Toggle from ABS to INC coordinate;

1. Toggle from INC to ABS coordinate;

1. Toggle from SDM to ABS coordinate;

4.5 1/2 Function

Function: Set the center of work piece as datum by halving the displayed value.

Example: Set the center of rectangle as datum as the right figure.

Steps:

1. Touch one side of the workpiece with the TOOL, then zero the X axis.

2. Take the TOOL to the opposite side of the workpiece and touch it. Then press + 1/2 in turn to value the X axis display value.

3. Move the machining table until "0.000" is displayed in X axis window. The position is the work-piece's center.

4.6 Clear All SDM datum.

In ABS mode, to continuously press ten times will cause to clear all the datum for 200 sets SDM. Message window displays "SDM CLR".

4.7 Sleeping Mode

In non-ABS mode, pressing the REF key can turn off all displays and the DRO enters Sleeping Mode. Pressing this key again will cause the DRO to return to working mode. In Sleeping Mode, the DRO is still in working state and actually records the tool movement.

Example: In non-ABS mode, press the REF key to access Sleeping Mode. In Sleeping Mode, press the REF key to quit Sleeping Mode.

4.8 Power Interruption Memory

The memory is used to store the settings of the DRO and machine reference values when power is turned off.

4.9 Search the Absolute Reference Point of Scale

During daily machining, it is very common that machining cannot be completed within one work shift, and hence the DRO has to be switched off after work, or power failure happens during machining, leading to loss of the workpiece datum (workpiece zero position). Re-establishing the workpiece datum using an edge finder or other method inevitably induces higher machining inaccuracy because it is not possible to re-establish the workpiece datum exactly at the previous position. To allow recovery of the workpiece datum very accurately without needing to re-establish it using an edge finder or other methods, every linear scale has a reference point location equipped with a reference position to provide datum point memory function.

The working principle of the reference datum memory function is as follows:

Since the reference point of the linear scale is permanent and fixed, it will never change or disappear when the DRO system is switched off. Therefore, we simply need to store the distance between the reference point and the workpiece datum (zero position) in non-volatile memory. Then, in case of power failure or the DRO being switched off, we can recover the workpiece datum (zero position) by presetting the display zero position as the stored distance from the reference point.

An absolute datum should be set when a workpiece is machined. There are three modes of operation (REF, AB, LEF_AB):

Example: to store the X axis work datum.

Example for REF mode:

1. DRO is set in ABS coordinate. Press REF, then the message window displays "REF".

2. Message window displays "REF". Press ENT until "FD_REF" appears in message window.

3. Select the axis which needs to search RI. For instance: select X axis, then press ☒. "X_REF" is displayed in message window, and X axis window flashes.

4. Move the machine table. The buzzer sounds when RI is searched, then the X window stops flashing and displays the value of the current position. The DRO returns to normal display state. Then the message window displays "FIND_X".

Example for AB mode:

1. DRO is set in ABS coordinate. Press REF, then the message window displays "REF".

2. Press ▲ ▼, then the message window displays "AB".

3. Message window displays "AB", press ENT until "FIND_AB" appears in the message window.

4. Select the axis which needs to search RI. For instance: select X axis, then press ☒. "X_REF" is displayed in the message window, and the X axis window flashes.

4. Select the axis which needs a reference index (RI) search. For instance: select the X axis, then press ☒. “X_REF” is displayed in the message window, and the X axis window flashes.

5. Move the machine table. The buzzer sounds when RI is searched, displaying the value of the current position for the absolute datum zero. The DRO returns to normal display state. Then the message window displays "FIND_AB".

1. DRO is set in ABS coordinate. Press REF, then the message window displays "REF".

2. Press ▲ ▼, then the message window displays "AB".

3. Message window displays "LEF_AB", press ENT until "ZERO_AB" appears in the message window.

3. The message window displays “LEF_AB”. Press ENT until “ZERO_AB” appears in the message window.

4. Move the machine table to the set zero position point. Then press X, and the X axis will zero. The current position becomes the absolute datum zero. The DRO returns to the normal display state.

NOTE: Linear range without reference point location of the user

4.10 Non Linear Error Compensation

First compensation Type (Linear or Non-Linear) in parameter setting must be set to Non-Linear. Linear scale have a ref point location and find to the Absolute Reference Point will be enable.

Default Non-Linear compensation: 50.

Example for Y axis:

Step 1: Search the Absolute Reference Point of Scale;

Step 2: Press NP, then the message window displays "COMP X".

Step 3: Press ▲ ▼, then the message window displays "COMP Y".

Step 4: Press ☐ENT, then the message window displays "NUMBER". Then input the compensation parameter NUMBER.

Step 5: Press ▲ ▼, then message window displays "Y-MSN-1" which indicates the step is to Non Linear Error Compensation.

Step 6: Input compensation value.

X window displays the value of the measurement value.

Y window displays the value of the standard value.

Example for the first compensation point:

Measurement value: 68.288mm. Standard value: 68.200mm

Step 7: After input all parameters, the DRO automatically exits.

5. 200 Groups SDM coordinate

The DRO has three display modes: the absolute mode (ABS), the incremental mode (INC), and the 200-group second data memory (SDM 1 - SDM200). The ABS datum of the workpiece is set at the beginning, and the 200-group SDM is set relative to the ABS coordinate.

ABS Mode, INC Mode, and SDM Mode are specially designed to provide much more convenience features to the operator to cope with batch machining of relative works and the machining of workpiece dimensions from more than one datum.

Example: The ABS datum is the center point O, and the points sdm1, sdm2, sdm3, sdm4 needed for processing are set as the datums of SDM 1 - SDM 4.

Two ways to set SDM coordinate:

1. Zeroing at the current point. 2. Presetting the datum of the SDM coordinate.

5.1 Zeroing at the Current Point

First, set the center point of the workpiece as the origin of the ABS. Then align the tool with points SDM1, SDM2, SDM3, SDM4 by moving the machine table and zero them. It is the position to process where the “0.000” appears in the X window and Y window by moving the machine table, whether in ABS or in SDM coordinate.

Steps:

1. Move the worktable to place the tool at the center of the workpiece point O as the datum of ABS. Then zero the X axis and Y axis in SDM 1; zero the X axis and Y axis in SDM 2; zero the X axis and Y axis in SDM 3; zero the X axis and Y axis in SDM 4.

2. Set point sdm1 as the datum of SDM 1. Move the machine worktable to x = 60.000, y = 45.000. Then process [X0] [Y0].

2. Set point sdm1 as the datum of SDM 2. Move the machine worktable to x = 60.000, y = -45.000. Then process [X0] [Y0].

3. Set point sdm1 as the datum of SDM 3. Move the machine worktable to x = -60.000, y = -45.000. Then process [X0] [Y0].

4. Set point sdm1 as the datum of SDM 4. Move the machine worktable to x = -60.000, y = 45.000. Then process [X0] [Y0].

5.2 Preset Datum of SDM Coordinate

There are the same examples as in Method 1. First, move the worktable to place the tool exactly at the origin of ABS. Secondly, enter the ABS Mode as follows.

Steps:

1. Move the worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero the X axis and Y axis in SDM 1; zero the X axis and Y axis in SDM 2; zero the X axis and Y axis in SDM 3; zero the X axis and Y axis in SDM 4.

2. Set point SDM1 as the datum of SDM 1. Press ▲ ▼, then the message window displays “SDM 1”. Input x = 60.000, y = 45.000.

3. Set point SDM1 as the datum of SDM 2. Press ▲ ▼, then the message window displays “SDM 2”. Input x = -60.000, y = 45.000.

4. Set point SDM1 as the datum of SDM 3. Press ▲ ▼, then the message window displays “SDM 3”. Input x = -60.000, y = -45.000.

5. Set point SDM1 as the datum of SDM 4. Press ▲ ▼, then the message window displays “SDM 4”. Input x = -60.000, y = 45.000.

6.10 EDM (Special customization function; if you need to purchase, please contact the dealer to customize)

1. Description: This function is used for the special machining of Electro Discharge Machining (EDM). When the set target value of the EDM Z-axis equals the present value, the digital readout will output a switch signal to control the EDM to stop the depth machining.

The setting of the Z-axis direction of the Digital Readout is shown in Fig 1, i.e., the deeper the depth, the larger the coordinate value of the Z-axis displays. Since starting machining, the depth will gradually deepen and the Z-axis value will increase.

According to the set Z-axis direction, the machining direction is divided into positive and negative machining. When the electrode descends and machining is carried out from up to down, the digital readout value will increase, which is called positive machining (Positive). This direction setting is the normal setting.

When the electrode ascends and machining is carried out from bottom to top, the digital readout value decreases. The machining direction is negative (negative), which is also called negative machining (as shown in Fig. 1).

The Digital Readout also features other functions, such as negative fireproof height. The negative fireproof height function is a kind of intelligent position-follow check safety protective device. During machining, the electrode surface will generate carbon accumulation. Due to long-time or continuous machining without tending, when carbon accumulation occurs and nobody cleans it, the electrode will slowly move in the negative direction. Once the electrode exceeds the liquid level, it will frequently catch fire and cause losses. This function is designed to address this problem. When setting the negative fireproof height, if the increased height of the electrode exceeds the height between it and the depth of the machined surface (i.e., the negative fireproof height), the digital readout display will blink as a warning; at the same time, the output signal will automatically turn off the EDM to eliminate the risk of fire.

Figure 1

2. Procedure:

See the following example for detailed machining.

1) Before machining, first set each parameter: DEPTH (machining depth), ERRHIGH (negative fireproof height), machining direction (POSITIVE / NEGATIVE), exit mode (AUTO/STOP), and EDM Relay Output Mode.

2) Move the main axis electrode of the Z-axis to make it contact the workpiece reference. Clear the A-axis to zero or set the value.

3) Enter EDM machining by pressing the EDM key.

4) The X-axis will display the machining depth target value. The Y-axis will display the value that has been machined to depth (the value on the Y-axis is the depth that the workpiece has been machined). The Z-axis will display the self-position real-time value (the value on the Z-axis is the position value of the main axis electrode of the Z-axis).

5) Start machining. The Z-axis display value will gradually approach the target value, and the Y-axis display value will also gradually approach the target value. If at this time the electrode moves up and down repeatedly, the Z-axis display value will change accordingly, but the Y-axis display value will not change; it will always display the machined depth value.

6) When the Z-axis display value equals the set target value, the position-reaching switch will be turned off, and the EDM will stop machining. According to the operator's setting, there are two exit modes:

a) Automatic Mode:

It will automatically exit from EDM machining status and recover to the original state before machining.

b) Stop Mode:

It will always stay at the machining interface after finishing machining, and you should press EDM to exit and return to the original state.

L0: Effective measuring length of the linear encoder; L1: Length of linear encoder mounting holes; L2: Linear encoder overall length

Maintenance:

1. The effective travel of the linear encoder should be longer than the maximum travel of the machine tool. If the length is not enough, replace the linear encoder with a larger stroke or add a limit block on the machine. The end position of the reading head from the end of the linear encoder body should be not less than 10 mm space (see the following diagram).

1. For any non-machined surface, a shim must be placed on the back of the linear encoder or a user-made installation shim must be used to ensure the stability and reliability of the connection between the grating ruler and the mounting surface.
2. When using a dial gauge or similar instrument to calibrate the parallelism of the linear encoder, the angle of the side head must be within ±30 degrees, and the smaller the angle, the better.

1. The installation position of the linear encoder must avoid direct impact from iron filings, oil, water, and dust (as shown in the figure below). The installation length of the L-plate should be as short as possible under possible circumstances, and the force situation of the mounting surface must be taken into consideration.

1. There must be a gap of 0.5 mm or more between the dust cover and the ruler body, and avoid contact between the dust cover and the ruler body when moving the reading head (as below).
2. Installation screw thread depth: at least 6 teeth of locking depth; for parts under greater force, such as the fixed plate supporting the digital display meter shelf, at least 8 teeth of locking depth; for YE series scales, the thread depth must be at least 8 teeth of locking depth. After tapping the mounting surface for M4 screws, deburr, remove paint, and clean off stains.

(The following figure)

1. The fixing of the signal line must take into account all relevant moving distances. Fixing position as far as possible placed in the very center of the stroke, and the excess signal line is fixed with a wire tie.
2. Adjustment of the scale height level must be the length of the scale center to take the two sides of the symmetry point Do adjust the reference point, any scale regardless of the school level direction or height direction, the Adjustment range: for the scale body, to the head from the scale body at a distance of not more than 20mm from each end shall prevail. For the reading head, between the two quadrilateral reference surfaces (the following figure)

1. The bending radius of the signal line of the scale is greater than 60mm.

10. Scale installation standard

(1) Installation base surface standard (Figure 4.8a, b, c three installation methods)

1. The installation surface of the ruler body is parallel to the installation surface of the reading head, and the parallelism between the installation surfaces is < 0.1 mm
2. The installation surface of the ruler body is perpendicular to the installation surface of the reading head, and the perpendicularity between the installation surfaces is < 0.1 mm

2) Ruler body installation standards (Figure 4.9, Figure 4.10)

1. Height direction relative to the machine guide parallelism <0.1mm, maximum not more than 0.15mm. In terms of symmetry point, the smaller the better.

3) Standard of reading head installation

1. The clearance between the reading head and the height direction of the ruler body is 0.8mm-1.6mm after installation, and then withdraw the pad block (Figure 4.11)

5. 200 Groups SDM Coordinate

The DRO has three display modes: the absolute mode (ABS), the incremental mode (INC), and the 200 groups second data memory (SDM 1 - SDM200). The ABS datum of the workpiece is set at the beginning, and the 200 groups SDM is set relative to the ABS coordinate.

ABS Mode, INC Mode, and SDM Mode are specially designed to provide much more convenience features to the operator to cope with the batch machining of relative works and the machining of workpiece dimensions from more than one datum.

Example: The ABS datum is the center point O, and the points SDM1, SDM2, SDM3, SDM4 needed for processing are set as the datum of SDM 1 - SDM 4.

Two ways to set SDM coordinate:

1. Zeroing at the current point. 2. Preset datum of SDM coordinate.

5.1 Zeroing at the Current Point

First, set the center point of the workpiece as the origin of the ABS, then align the tool with points SDM1, SDM2, SDM3, SDM4 by moving the machine table and zero them. It is the position to process where the "0.000" appears in the X window and Y window by moving the machine table, whether in ABS or in SDM coordinate.

Steps:

1. Move the worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero X axis and Y axis in SDM 1; zero X axis and Y axis in SDM 2; zero X axis and Y axis in SDM 3; zero X axis and Y axis in SDM 4.

2. Set the point sdm1 as the datum of SDM 1. Move the machine worktable to x = 60.000, y = 45.000. Then process _{0 0} .

2. Set the point sdm1 as the datum of SDM 2. Move the machine worktable to x = 60.000, y = -45.000. Then process _{0 0} .

3. Set the point sdm1 as the datum of SDM 3. Move the machine worktable to x = -60.000, y = -45.000. Then process _{0 0} .

4. Set the point sdm1 as the datum of SDM 4. Move the machine worktable to x = -60.000, y = 45.000. Then process _{0 0} .

5.2 Preset datum of SDM coordinate

There are the same sample as Method 1. First move the worktable to place the TOOL exactly at the origin of ABS, secondly enter the ABS Mode as follows.

Steps:

1. Move worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero X axis and Y axis in SDM 1; zero X axis and Y axis in SDM 2; zero X axis and Y axis in SDM 3; zero X axis and Y axis in SDM 4.

2. Set point sdm1 as the datum of SDM 1. Press ▲ ▼, then the message window displays “SDM 1”. Input x = 60.000, y = 45.000.

3. Set point sdm1 as the datum of SDM 2. Press ▲ ▼, then the message window displays “SDM 2”. Input x = -60.000, y = 45.000.

4. Set point sdm1 as the datum of SDM 3. Press ▲ ▼, then the message window displays “SDM 3”. Input x = -60.000, y = -45.000.

5. Set point sdm1 as the datum of SDM 4. Press ▲ ▼, then the message window displays “SDM 4”. Input x = -60.000, y = 45.000.

The DRO has three display modes: the absolute mode (ABS), the incremental mode (INC) and the 200 groups second data memory (SDM 1 - SDM200). ABS datum of the work-piece is set at the beginning and the 200 groups SDM is set relative to ABS coordinate.

ABS Mode, INC Mode and SDM Mode are specially designed to provide much more convenience features to the operator to cope with the batch machining of relative works and the machining of the workpiece machining dimensions from more than one datum.

Example: The ABS datum is the center point O, the points sdm1, sdm2, sdm3, sdm4 needed processing are set as datum of SDM 1 - SDM 4.

Two ways to set SDM coordinate:

1. Zeroing at the Current Point. 2. Preset datum of SDM coordinate.

5.1 Zeroing at the Current Point

First, set the center point of the workpiece as the origin of the ABS. Then align the TOOL with points SDM1, SDM2, SDM3, SDM4 by moving the machine table and zero them. It is the position to process where the “0.000” appears in the X window and Y window by moving the machine table, whether in ABS or in SDM coordinate.

Steps:

1. Move the worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero X axis and Y axis in SDM 1; zero X axis and Y axis in SDM 2; zero X axis and Y axis in SDM 3; zero X axis and Y axis in SDM 4.

2. Set the point SDM1 as the datum of SDM 1. Move the machine worktable to x = 60.000, y = 45.000. Then process [X0] [Y0].

2. Set the point SDM1 as the datum of SDM 2. Move the machine worktable to x = 60.000, y = -45.000. Then process [X0] [Y0].

3. Set the point SDM1 as the datum of SDM 3. Move the machine worktable to x = -60.000, y = -45.000. Then process [X0] [Y0].

4. Set the point SDM1 as the datum of SDM 4. Move the machine worktable to x = -60.000, y = 45.000. Then process [X0] [Y0].

5.2 Preset datum of SDM coordinate

There are the same steps as Method 1. First, move the worktable to place the TOOL exactly at the origin of ABS. Secondly, enter the ABS Mode as follows.

Steps:

1. Move the worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero X axis and Y axis in SDM 1; zero X axis and Y axis in SDM 2; zero X axis and Y axis in SDM 3; zero X axis and Y axis in SDM 4.

2. Set point SDM1 as the datum of SDM 1. Press ▲ ▼, then the message window displays “SDM 1”. Input x = 60.000, y = 45.000.

5. 200 Groups SDM Coordinate

The DRO has three display modes: the absolute mode (ABS), the incremental mode (INC), and the 200 groups second data memory (SDM 1 - SDM200). The ABS datum of the workpiece is set at the beginning, and the 200 groups SDM is set relative to the ABS coordinate.

ABS Mode, INC Mode, and SDM Mode are specially designed to provide much more convenience features to the operator to cope with the batch machining of relative works and the machining of the workpiece machining dimensions from more than one datum.

Example: The ABS datum is the center point O, and the points sdm1, sdm2, sdm3, sdm4 needed for processing are set as the datum of SDM 1 - SDM 4.

Two ways to set SDM coordinate:

1. Zeroing at the current point. 2. Preset datum of SDM coordinate.

5.1 Zeroing at the Current Point

First, set the center point of the workpiece as the origin of the ABS. Then align the tool with points SDM1, SDM2, SDM3, SDM4 by moving the machine table and zero them. It is the position to process where the “0.000” appears in the X window and Y window by moving the machine table, whether in ABS or in SDM coordinate.

Steps:

1. Move the worktable to place the tool at the center of the workpiece point O as the datum of ABS. Then zero the X axis and Y axis in SDM 1; zero the X axis and Y axis in SDM 2; zero the X axis and Y axis in SDM 3; zero the X axis and Y axis in SDM 4.

2. Set the point sdm1 as the datum of SDM 1. Move the machine worktable to x = 60.000, y = 45.000. Then process X0 Y0.

2. Set the point sdm1 as the datum of SDM 2. Move the machine worktable to x = 60.000, y = -45.000. Then process X0 Y0.

3. Set the point sdm1 as the datum of SDM 3. Move the machine worktable to x = -60.000, y = -45.000. Then process X0 Y0.

4. Set the point sdm1 as the datum of SDM 4. Move the machine worktable to x = -60.000, y = 45.000. Then process X0 Y0.

5.2 Preset Datum of SDM Coordinate

The procedure is the same as Method 1. First, move the worktable to place the tool exactly at the origin of ABS. Then, enter the ABS mode as follows.

Steps:

1. Move the worktable to place the tool at the center of the workpiece point O as the datum of ABS. Then zero the X and Y axes in SDM 1; zero the X and Y axes in SDM 2; zero the X and Y axes in SDM 3; zero the X and Y axes in SDM 4.

2. Set point SDM1 as the datum of SDM 1. Press ▲ ▼, then the message window displays “SDM 1”. Input x = 60.000, y = 45.000.

3. Set point SDM1 as the datum of SDM 2. Press ▲ ▼, then the message window displays “SDM 2”. Input x = -60.000, y = 45.000.

4. Set point SDM1 as the datum of SDM 3. Press ▲ ▼, then the message window displays “SDM 3”. Input x = -60.000, y = -45.000.

5. Set point SDM1 as the datum of SDM 4. Press ▲ ▼, then the message window displays “SDM 4”. Input x = -60.000, y = 45.000.

5. 200 Groups SDM Coordinate

The DRO has three display modes: the absolute mode (ABS), the incremental mode (INC), and the 200 groups second data memory (SDM 1 - SDM200). The ABS datum of the workpiece is set at the beginning, and the 200 groups SDM is set relative to the ABS coordinate.

ABS Mode, INC Mode, and SDM Mode are specially designed to provide much more convenience features to the operator to cope with the batch machining of relative works and the machining of workpiece dimensions from more than one datum.

Example: The ABS datum is the center point O, and the points sdm1, sdm2, sdm3, sdm4 needed for processing are set as the datum of SDM 1 - SDM 4.

Two ways to set SDM coordinate:

1. Zeroing at the current point. 2. Preset datum of SDM coordinate.

5.1 Zeroing at the Current Point

At first, set the center point of the workpiece as the origin of the ABS, then align the tool with points SDM1, SDM2, SDM3, SDM4 by moving the machine table and zero them. It is the position to process where the “0.000” appears in the X window and Y window by moving the machine table whether in ABS or in SDM coordinate.

Steps:

1. Move the worktable to place the tool at the center of the workpiece point O as the datum of ABS. Then zero the X axis and Y axis in SDM 1; zero the X axis and Y axis in SDM 2; zero the X axis and Y axis in SDM 3; zero the X axis and Y axis in SDM 4.

2. Set the point sdm1 as the datum of SDM 1. Move the machine worktable to x = 60.000, y = 45.000. Then process [X0] [Y0].

2. Set the point sdm1 as the datum of SDM 2. Move the machine worktable to x = 60.000, y = -45.000. Then process [X0] [Y0].

3. Set the point sdm1 as the datum of SDM 3. Move the machine worktable to x = -60.000, y = -45.000. Then process [X0] [Y0].

4. Set the point sdm1 as the datum of SDM 4. Move the machine worktable to x = -60.000, y = 45.000. Then process X0 Y0.

5.2 Preset datum of SDM coordinate

There are the same sample as Method 1. First move the worktable to place the TOOL exactly at the origin of ABS, secondly enter the ABS Mode as follow.

Steps:

1. Move worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero X axis and Y axis in SDM 1; zero X axis and Y axis in SDM 2; zero X axis and Y axis in SDM 3; zero X axis and Y axis in SDM 4.

2. Set point sdm1 as the datum of SDM 1. Press ▲ ▼, then the message window displays "SDM 1". Input x = 60.000, y = 45.000.

3. Set point sdm1 as the datum of SDM 2. Press ▲ ▼, then the message window displays "SDM 2". Input x = -60.000, y = 45.000.

4. Set point sdm1 as the datum of SDM 3. Press ▲ ▼, then the message window displays "SDM 3". Input x = -60.000, y = -45.000.

5. Set point sdm1 as the datum of SDM 4. Press ▲ ▼, then the message window displays "SDM 4". Input x = -60.000, y = 45.000.

5. 200 Groups SDM Coordinate

The DRO has three display modes: the absolute mode (ABS), the incremental mode (INC), and the 200 groups second data memory (SDM 1 - SDM200). The ABS datum of the workpiece is set at the beginning, and the 200 groups SDM is set relative to the ABS coordinate.

ABS Mode, INC Mode, and SDM Mode are specially designed to provide much more convenience features to the operator to cope with the batch machining of relative works and the machining of workpiece dimensions from more than one datum.

Example: The ABS datum is the center point O, and the points sdm1, sdm2, sdm3, sdm4 needed for processing are set as datums of SDM 1 - SDM 4.

Two ways to set SDM coordinate:

1. Zeroing at the current point. 2. Presetting the datum of SDM coordinate.

5.1 Zeroing at the Current Point

First, set the center point of the workpiece as the origin of the ABS. Then align the tool with points SDM1, SDM2, SDM3, SDM4 by moving the machine table and zero them. It is the position to process where the "0.000" appears in the X window and Y window by moving the machine table, whether in ABS or in SDM coordinate.

Steps:

1. Move the worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero X axis and Y axis in SDM 1; zero X axis and Y axis in SDM 2; zero X axis and Y axis in SDM 3; zero X axis and Y axis in SDM 4.

2. Set the point sdm1 as the datum of SDM 1. Move the machine worktable to x = 60.000, y = 45.000. Then process X0 Y0.

2. Set the point sdm1 as the datum of SDM 2. Move the machine worktable to x = 60.000, y = -45.000. Then process X0 Y0.

3. Set the point sdm1 as the datum of SDM 3. Move the machine worktable to x = -60.000, y = -45.000. Then process X0 Y0.

4. Set the point sdm1 as the datum of SDM 4. Move the machine worktable to x = -60.000, y = 45.000. Then process X0 Y0.

5.2 Preset datum of SDM coordinate

There are the same sample as Method 1. First move the worktable to place the TOOL exactly at the origin of ABS, secondly enter the ABS Mode as follow.

Steps:

1. Move worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero X axis and Y axis in SDM 1; zero X axis and Y axis in SDM 2; zero X axis and Y axis in SDM 3; zero X axis and Y axis in SDM 4.

2. Set point sdm1 as the datum of SDM 1. Press ▲ ▼, then the message window displays “SDM 1”. Input x = 60.000, y = 45.000.

3. Set point sdm1 as the datum of SDM 2. Press ▲ ▼, then the message window displays “SDM 2”. Input x = -60.000, y = 45.000.

4. Set point sdm1 as the datum of SDM 3. Press ▲ ▼, then the message window displays “SDM 3”. Input x = -60.000, y = -45.000.

5. Set point sdm1 as the datum of SDM 4. Press ▲ ▼, then the message window displays “SDM 4”. Input x = -60.000, y = 45.000.

5. 200 Groups SDM Coordinate

The DRO has three display modes: the absolute mode (ABS), the incremental mode (INC), and the 200 groups second data memory (SDM 1 - SDM200). The ABS datum of the workpiece is set at the beginning, and the 200 groups SDM is set relative to the ABS coordinate.

ABS Mode, INC Mode, and SDM Mode are specially designed to provide much more convenience features to the operator to cope with the batch machining of relative works and the machining of the workpiece machining dimensions from more than one datum.

Example: The ABS datum is the center point O, and the points sdm1, sdm2, sdm3, sdm4 needed for processing are set as the datum of SDM 1 - SDM 4.

Two ways to set SDM coordinate:

1. Zeroing at the current point. 2. Preset datum of SDM coordinate.

5.1 Zeroing at the Current Point

First, set the center point of the workpiece as the origin of the ABS. Then align the tool with points SDM1, SDM2, SDM3, SDM4 by moving the machine table and zero them. It is the position to process where the “0.000” appears in the X window and Y window by moving the machine table, whether in ABS or in SDM coordinate.

Steps:

1. Move the worktable to place the tool at the center of the workpiece point O as the datum of ABS. Then zero the X axis and Y axis in SDM 1; zero the X axis and Y axis in SDM 2; zero the X axis and Y axis in SDM 3; zero the X axis and Y axis in SDM 4.

2. Set the point sdm1 as the datum of SDM 1. Move the machine worktable to x = 60.000, y = 45.000. Then process X0 Y0.

2. Set the point sdm1 as the datum of SDM 2. Move the machine worktable to x = 60.000, y = -45.000. Then process X0 Y0.

3. Set the point sdm1 as the datum of SDM 3. Move the machine worktable to x = -60.000, y = -45.000. Then process X0 Y0.

4. Set the point sdm1 as the datum of SDM 4. Move the machine worktable to x = -60.000, y = 45.000. Then process X0 Y0.

5.2 Preset Datum of SDM Coordinate

The procedure is the same as Method 1. First, move the worktable to place the tool exactly at the origin of ABS. Then, enter the ABS mode as follows.

Steps:

1. Move the worktable to place the tool at the center of the workpiece point O as the datum of ABS. Then zero the X axis and Y axis in SDM 1; zero the X axis and Y axis in SDM 2; zero the X axis and Y axis in SDM 3; zero the X axis and Y axis in SDM 4.

2. Set point SDM1 as the datum of SDM 1. Press ▲ ▼, then the message window displays “SDM 1”. Input x = 60.000, y = 45.000.

3. Set point SDM1 as the datum of SDM 2. Press ▲ ▼, then the message window displays “SDM 2”. Input x = -60.000, y = 45.000.

4. Set point SDM1 as the datum of SDM 3. Press ▲ ▼, then the message window displays “SDM 3”. Input x = -60.000, y = -45.000.

5. Set point SDM1 as the datum of SDM 4. Press ▲ ▼, then the message window displays “SDM 4”. Input x = -60.000, y = 45.000.

5. 200 Groups SDM coordinate

The DRO has three display modes: the absolute mode (ABS), the incremental mode (INC) and the 200 groups second data memory (SDM 1 - SDM200). ABS datum of the work-piece is set at the beginning and the 200 groups SDM is set relative to ABS coordinate.

ABS Mode, INC Mode and SDM Mode are specially designed to provide much more convenience features to the operator to cope with the batch machining of relative works and the machining of the workpiece machining dimensions from more than one datum.

Example: The ABS datum is the center point O, and the points sdm1, sdm2, sdm3, sdm4 that need processing are set as the datums of SDM 1 - SDM 4.

Two ways to set SDM coordinates:

1. Zeroing at the current point. 2. Presetting the datum of the SDM coordinate.

5.1 Zeroing at the Current Point

First, set the center point of the workpiece as the origin of the ABS. Then align the TOOL with points SDM1, SDM2, SDM3, and SDM4 by moving the machine table and zero them. It is the position to process where the "0.000" appears in the X window and Y window by moving the machine table, whether in ABS or in SDM coordinate.

Steps:

1. Move the worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero the X axis and Y axis in SDM 1; zero the X axis and Y axis in SDM 2; zero the X axis and Y axis in SDM 3; zero the X axis and Y axis in SDM 4.

2. Set the point sdm1 as the datum of SDM 1. Move the machine worktable to x = 60.000, y = 45.000. Then process [X0] [Y0].

2. Set the point sdm1 as the datum of SDM 2. Move the machine worktable to x = 60.000, y = -45.000. Then process [X0] [Y0].

3. Set the point sdm1 as the datum of SDM 3. Move the machine worktable to x = -60.000, y = -45.000. Then process [X0] [Y0].

4. Set the point sdm1 as the datum of SDM 4. Move the machine worktable to x = -60.000, y = 45.000. Then process [X0] [Y0].

5.2 Presetting the datum of SDM coordinate

There are the same examples as in Method 1. First, move the worktable to place the TOOL exactly at the origin of ABS. Secondly, enter the ABS Mode as follows.

Steps:

1. Move the worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero the X axis and Y axis in SDM 1; zero the X axis and Y axis in SDM 2; zero the X axis and Y axis in SDM 3; zero the X axis and Y axis in SDM 4.

2. Set point SDM1 as the datum of SDM 1. Press ▲ ▼, then the message window displays “SDM 1”. Input x = 60.000, y = 45.000.
