3.17 High Speed Settings – CYCLE832 (SW 6.3 and higher)
The standard cycle High Speed Settings CYCLE832 is available for
the HMI in SW 6.3 and higher and NCU SW 6.3 (CCU SW 4.3).
Application of CYCLE832:
• for technological support when machining free-form
contours (surfaces) in the 3- or 5-axis high-speed
machining range (High Speed Cutting - HSC)
• used predominantly in the HSC milling range
(possibility of use for turning or grinding)
• groups the important G codes and machine and
setting data that are needed for HSC machining
• technology / geometry separation by relevant NC
program architecture
When executing CAM programs in the HSC range, the control has to process high feedrates with
the shortest NC blocks. The user expects a good surface finish with great accuracy in the 1 µ m
range with extremely high machining feedrates >10 m/min. By applying different machining
strategies, the user can fine-tune the program with the aid of CYCLE832.
When roughing, smoothing the contour puts the weighting on speed.
When finishing, enabling the NC block compressor puts the weighting on accuracy.
In both cases, specifying a tolerance retains the machining contour in order to achieve the desired
surface finish.
When defining the tolerance values for smoothing the contour, the operator must have precise
knowledge of the subsequent CAM program. The CYCLE832 cycle supports machine types
where a maximum of three linear and two rotary axes are involved in the machining.
The following functions can be defined or enabled/disabled
by CYCLE832:
• Tolerance band of the contour to be machined
• Smoothing (G64, G641, G642)
• NC block compressor (COMPCAD, COMPCURV, COMPOF)
• Feedforward control (FFWON, FFWOF)
• Jerk limitation (SOFT, BRISK)
• 5-axis transformation (TRAORI, TRAFOF)
• B spline
