Programming example 2

Measure radius of milling tool (workpiece-related)
Milling tool T4 with D1 is to be remeasured in radius R (to ascertain wear).
Radius measurement is to be performed with rotating spindle – in the X axis.
A measured value deviation of < 0.6 mm compared with the entered values is expected.
Values of calibration tool T4 D1,
before the measurement:
Tool type (DP1):
Length 1 - geometry (DP3):
Radius - geometry (DP6):
Radius - wear (DP15):
Values of the settable ZO for G54:
Tool probe 1 is used. It has already been
calibrated under the same conditions
(G17, G54, ...).
Values: See programming example 2
