Cali block thickness
Height difference from the top surface of tool sensor to its
bottom surface
0~100
The measurement method of this parameter is:
Manually move the Z-axis to the certain point on 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 sensor on workpiece surface→ shift down Z-axis slowly until
reaching the tool sensor and getting the
calibration signal→ the system will record the current
coordinate Z2 of Z-axis
Z2 subtracts Z1, and its result equals to the thickness of tool sensor. Enter the result into the
parameter
“Cali block thickness.”
3.7.3 Measure Tool Length/ Set Tool Length
The process of measuring tool length is similar to that of floating tool presetting, which calls floating
presetting sub-programs however. The difference between the two lies in that when measuring tool
length finishes the result is saved in the tool offset instead of workpiece offset. Users can press F7 under
Parameter section to check the tool offset result when complete the measurement.
In machining, because of tool change caused by tool break or other reasons , the length and clamped
position of tools must be different. Users need to execute tool length measurement to confirm tool offset
again. This tool presetting method is often used in multi-tool mode.
In presetting, record the machine coordinate of tool nose contacting the tool sensor surface, and then
minus the
“floating tool sensor thickness” and set the calculated value into the tool offset.

The steps of measuring tool length:
1) Select the tool according to its tool number;
2) Measure the tool length of the selected tool and record tool offset;
