LH71/LH72 Tool offset function Operating manual
Make sure lamp is lit.
If the lamp is not lit, press key to enter tool offset mode.
Set the tool number to #1.
Operate the key, numeric key, and key on the lower display to enter "1".
Tool master coordinate setting (for scale with reference point):
Set any position within the effective scale length range as the datum point (X, Z = 0,0). This operation
method describes the operation to set the center of the machine movable range as the datum point.
1.
The tool master is # 99 and moves the cutting tool holder so that it is approximately in the center of the range of motion
on the X and Z axes.
Move the tool post to the center of
the movable range of the X-axis and
Z-axis
Enter the reference value directly on the X-axis and Z-axis.
Press the X-axis key, enter the numerical value 0.0, and press key.
2.
Set the Z-axis datum value .
Press the Z-axis key and enter the number(0.0). And press key
The X-axis datum point value is now saved in memory in the tool master # 99.
Set the Z-axis datum value to zero (0)
Z
axis
Set the X-axis datum value to zero (0)

This completes the setting of the X-axis and Z-axis datum point for the tool master #99.

Setting the number and offset value of the tool to be used:
Set the cutting tool to be actually used on the cutting tool holder, perform machining, measure the
dimensions of the workpiece, and enter the value.
Up to
step 2
, you have performed the operations related to the tool master settings. In step 3, set the tool to be actually used.
The procedure is as follows.
①
Set the number of the tool (byte) to be used
②
Machine the workpiece with the tool and enter its dimensions on the X and Z axes
When setting another tool, set the tool number in the same way (switch tool number), execute machining, measure the workpiece, and
set its value.

Attach the bite to the tool post. (Fig.1).
Enter the tool number of this byte (here, number 1) to switch the display.

Move the measuring unit to pass the reference point.
This completes the setting of the X-axis and Z-axis datum point for the tool master #99.
NOTE:
When the 2-axis addition function is used on the Z-axis, the reference point detection is enabled on both the Z1 and Z2 axes
on the display unit side. Therefore, if the position of either measuring unit shifts, the reference position will shift.
