Calibrate Tool

Through calibrating tool, you can set tool offset and then define the specific location for
workpiece coordinate system.
NK280B offers two methods of calibrating tool.

Execute Fixed Calibration

During calibrating tool, the system will record the machine coordinate when tool nose touches
the surface of tool sensor. (Tool offset at this time is equal to the value of machine coordinate.)
When you need to calibrate several tools, switch tool through T command and then proceed the
following steps.
To execute fixed calibration:
1. Select a tool for tool calibration.
2. Do one of the following:
• Under Auto mode, press State > A > F5.
• Under Jog/Handwheel/Stepping mode, press State > A > F3.
3. Calibrate tool:
Condition
