Machining methods
With the "High Speed Settings" function, you can select between four technological
machining types:
● "Finishing"
● "Rough-finishing"
● "Roughing"
● "Deselected" (default setting)
For CAM programs in the HSC range, the four machining types directly relate to the
accuracy and speed of the path contour (see help screen).
The operator/programmer uses the tolerance value to give a corresponding weighting.
Corresponding to the appropriate G commands, the four machining types are assigned to
technology G group 59:
Machining type
Deselection
Finishing
Rough-finishing
Roughing
Additional G commands that are available in conjunction with machining free-form surfaces,
are also activated in the High Speed Settings cycle.
When deselecting CYCLE832, the G groups are programmed to the settings - during the
program run time - that are declared in the machine data for the reset state.
