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.
The "High Speed Settings" cycle is also in conjunction with the "Advanced Surface" function.
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.
