8.9 Call work offsets

Converting the spindle speed (S) / cutting rate (V) when milling
As an alternative to the cutting rate, you can also program the spindle speed.
For the milling cycles, the cutting rate (m/min) that is entered is automatically converted into
the spindle speed (rpm) using the tool diameter - and vice versa.
Machining
When machining some cycles, you can choose between roughing, finishing, or complete
machining. For certain milling cycles, finishing edge or finishing base are possible.
● Roughing
One or more machining operations with depth infeed
● Finishing
Single machining operation
● Edge finishing
Only the edge of the object is finished
● Base finishing
Only the base of the object is finished
● Complete machining
R oughing and finishing with one tool in a
● machining step
If you want to rough and finish using two different tools, you must call the machining cycle
twice (1st block = roughing; 2nd block = finishing). The programmed parameters are
retained when the cycle is called for the second time.
8.9 Call work offsets
You can call work offsets (G54, etc.) from any program.
You define work offsets in work offset lists. You can also view the coordinates of the selected
offset here.
