FANUC Series 30i-MODEL A
Input of tool offset value measured
1.1 Operation for direct input of tool offset value
Setting of offset value
1 Cut surface A in manual mode with an actual tool. Suppose that a workpiece coordinate
system has been set.
Surface B
Surface A
2 CNC memorized absolute coordinate value of z axis, when PRC signal on the machine is
turned on “1”,then the tool can retract along two axes and spindle stop.
3 Measure distance 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:
3-1 Press the function key OFFSET/SETTING or the soft key [OFFSET] to display
the tool compensation screen. If geometry compensation values and wear
compensation values are separately specified, display the screen for either of them.
