To set the difference between the tool reference position used in
programming (the nose of the standard tool, turret center, etc.) and the tool
tip position of a tool actually used as an offset value
Procedure for direct input of tool offset value
1 Cut surface A in manual mode with an actual tool.
Suppose that a workpiece coordinate system has been set.

Z
Surface A
Surface B
2 Release the tool in X axis direction only, without moving Z axis and
stop the spindle.
3 Measure distance β from the zero point in the workpiece coordinate
system to surface A.
Set this value as the measured value along the Z–axis for the desired
offset number, using the following procedure:
