Measurement with rotating / stationary spindle
Measurement is possible with a rotating (M3, M4) or with a stationary milling spindle (M5).
If the milling spindle is stationary, at the beginning it is positioned at the specified starting
angle SPOS.
Note
Measurement with rotating spindle
If selection of a specific milling tool cutting edge is not possible, it is possible to measure with
a rotating spindle. The user must then program the direction of rotation, speed, and feedrate
very carefully before calling up CYCLE982 to prevent damage to the probe. A low speed and
feedrate must be selected.
Empirical values may optionally be included. A mean value is not calculated.
Preconditions
● The tool probe must be calibrated, see Calibrate probe (CYCLE982) (Page 178).
● The approximate tool dimensions must be entered in the tool offset data:
● The tool to be measured must be active with its tool offset values when the cycle is
● For a milling cutter, the channel-specific SD 42950: $SC_TOOL_LENGTH_TYPE = 2
● The tool spindle must be declared as the master spindle.
