3.6 High speed settings – CYCLE832
Application
You can influence the sequence of NC programs using SINUMERIK CYCLE832. It provides
technological support for 3- and 5-axis machining in the high speed cutting (HSC) range.
CYCLE832 brings together the key programming codes, or G codes, required for HSC.
CYCLE832 can be set by the machine operator or, within the context of NC program generation,
by the post processor or programmer. At machine level, the operator can also control how it is
executed by changing certain parameters.
When executing CAM programs with very short NC blocks in the HSC range, the control needs to
achieve high machining feedrates of >10 m/min. By applying different machining strategies, you
can use CYCLE832 to fine-tune the program.
When roughing, the emphasis is on speed due to the smoothing of the contour.
When finishing, the emphasis is on surface quality and accuracy.
In both cases, specifying a tolerance ensures that the correct machining contour is achieved in
order to obtain the desired surface quality and accuracy. Generally, a higher tolerance is
selected for roughing than for finishing.
