Reading the cutting rate and the spindle speed programming variant
The cutting rate of a spindle and the speed programming variant (spindle speed S or cutting
rate SVC) can be read using system variables:
• With preprocessing stop in the part program via system variables:
• Without preprocessing stop in the part program via system variables:

Cutting rate applied when the current main run record for
spindle number <n> was preprocessed.
Spindle speed programming variant applied when the
current main run record for spindle number <n> was
preprocessed.
