High-speed settings (CYCLE832)

Function
Machining of free-form surfaces involves high requirements regarding velocity, precision and
surface quality.
You can achieve optimum velocity control depending on the type of processing (roughing,
rough-finishing, finishing) very simply with the "High Speed Settings" cycle.
Program the cycle in the technology program before the geometry program is called.
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:
