Process

With helical drill milling, the tool moves to the specified machining depth at the selected spindle speed and feedrate in a helical motion G02/G03. The hole is produced in one operation down to the final drilling depth. The end point on the X and Y axes is calculated internally in the cycle.

Optionally, a flat milled recess can be commanded for the basic hole at the end of the helical drilling operation. This is followed by positioning the tool in the drilling centre without dwell time at rapid traverse G00 and moved to the retraction plane.
