Process

To ensure that the cycle is executed successfully, the following requirements must be fulfilled:

• 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 every plunge position, the tool drills down to the specified machining depth at the selected spindle speed and at the transferred feedrate. The hole is produced in a single operation down to the final drilling depth. After the drilling operation, the tool is retracted in rapid traverse to the specified retraction plane before the next drill hole is approached.
