Mobile Calibration
Mobile calibration can be used to set the workpiece origin of Z-axis, and the thickness of tool
presetter is determined by parameter
―Cali Block Thickness‖. System will automatically set the
workpiece offset after mobile calibration.
Workpiece offset = machine coordinate
– thickness of tool presetter – public offset – tool offset
Generally, the default setting values of public offset and tool offset are both ―0‖.
The sketch map of the process of mobile calibration is shown in Fig. 3-17.

Cali Block Thickness
Height difference from the top surface
of tool presetter to its bottom surface
0~100 (mm)
The measurement method of this parameter is:
Manually move the Z-axis to a certain point over
workpiece surface→ shift down its tool nose
until reaching the surface of workpiece→ the system will record the current coordinate Z1 of
Z-axis.
Uplift Z-
axis→ put the tool presetter on workpiece surface→ shift down Z-axis slowly until
reaching the tool presetter and getting the presetter
signal→ system will record the current
