Process

To ensure that the cycle is executed successfully, the following requirements must be met.

• Tool length compensation is active.
• The spindle speed must be selected before the cycle is started.
• The contour can be reached without collision starting from the current position at the height of the retraction plane.
• The contours used were already programmed using #CONTOUR BEGIN / #CONTOUR END.
• The defined contours for the edge contour and islands are closed, i.e. start and end points are identical.

The necessary plunge positions in the cycle are calculated and approached one after the other on the retraction plane. For each plunge position, the tool drills to the specified machining depth in multi-step operations at the selected spindle speed and feedrate G01. The number of infeeds is programmable. The resulting feed depth is determined internally in the cycle based on the final drilling depth. A different feed depth can be defined for the first infeed.
