Positioning
Positioning motion between the grooves:
Straight line:
Next position is approached linearly at rapid traverse.
Circular:
Next position is approached at the programmed feedrate FP along a circular path.
8.2.9 Open groove (CYCLE899)
Function.
Use the "Open slot" function if you want to machine open slots.
For roughing, you can choose between the following machining strategies, depending on
your workpiece and machine properties.
Vortex milling
Plunge cutting
The following machining types are available to completely machine the slot:
Roughing
Rough-finishing
Finishing
Base finishing
Edge finishing
Chamfering
