except for path milling. You can machine with or without radius
compensation in conjunction with the "Path milling" and "Line"
functions. In the case of the "Line" function, the tool radius
compensation has a modal action, i.e. it is not automatically
deactivated again.

The spindle speed (S) determines the number of spindle rotations per
minute. The CW/CCW setting is made in the tool list in ShopMill.
Programming:
The spindle speed is input when a new tool is loaded into the spindle.
As an alternative to spindle speed, a cutting rate (V) can be specified
in m/min.
Spindle start/spindle stop:
The spindle is started directly after a new tool has been loaded. It is
stopped on Reset, end of program or tool change.
Peripheral speed at which the tool cutting edge machines the
workpiece. Cutting rates (V) are specified in m/min.
