High Speed Settings - CYCLE832

Application
You can influence the sequence of CAM programs using SINUMERIK CYCLE832. It provides
technological support for 3- and 5-axis machining in the high-speed cutting (HSC) range.
When executing CAM programs in the HSC range, the control needs to achieve high machining
feedrates. By applying different machining strategies, you can use CYCLE832 to fine-tune the
program for execution.
When roughing, the emphasis is on velocity 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, for roughing the tolerance is
greater than for finishing.
Advanced Surface and Top Surface
For CYCLE832, as of software release V4.7 SP2, you can select between Advanced Surface
and option Top Surface.
Top Surface is an option of CYCLE832 - and is based on the COMPSURF compressor. This has
been improved for machining demanding CAD/CAM programs. The new compressor especially
compensates the potential negative impact on the surface quality for an inhomogeneous point
distribution, as is the case for inclined line-by-line finishing programs and for bidirectional milling.
The result is a uniformly perfect surface, which is essentially independent of the quality of the
CAD/CAM data.
