Refer to "3 (II). Tool Offset (M system)" for M system.

 

By using a device having a touch sensor, the tool compensation amount can be calculated just by 
contacting the tool nose against the touch sensor with manual feed. The calculated results are stored in 
the tool compensation amount memory. 
After setting the tool compensation amount for each tool, the Z axis external workpiece coordinate 
offset data can be set by cutting the edges of the workpiece with manual operation and inputting the 
workpiece measurement signal.

1.  Set the machine coordinate values of the touch sensor's contact surface in the parameters 

beforehand as the measurement basic value. 

2.  Select the tool for which the tool compensation amount is to be measured. 
3.  Using manual feed, contact the nose of the tool against the touch sensor. 
 The 

tool 

compensation 

amount will be calculated from the machine coordinate value when the 

touch sensor is contacted and the measurement basic value, and will be saved in the memory 
as the tool compensation amount. 

Tool compensation amount = 
  Machine coordinate value – measurement basic value (sensor position) 

 
 

After measuring, the tool wear amounts for the individually designated tool numbers are 
cleared. 

 

The system 1 X (1st axis), Z (2nd axis), additional axis, and system 2 X (1st axis), Z (2nd axis), 
additional axis can be set. The additional axis is determined with the #1520 Tchg34 additional axis 
tool compensation operation selection parameter.

Note that the tools in the two systems cannot be measured simultaneously.
