SysMillContourPreDrilling - Predrilling with contour milling

This cycle is used to predrill for contour milling.

The cycle can be used both in combination with the pocket milling cycle (reference cycle = SysMillContourPocket) and with the spigot milling cycle (reference cycle = SysMillContourSpigot). The plunge points required for roughing are considered for predrilling.

For example, a typical process that results here when the contour pocket milling cycle is used can look as follows:

• Predrilling (SysMillContourPreDrilling.ecy)
• Tool change
• Mill contour pocket (= SysMillContourPocket.ecy)

If several contours are to be milled, it may be practical to make multiple calls of the predrilling cycle before the contour is machined. This avoids unnecessary tool changes.

• Predrill contour pocket 1 (SysMillContourPreDrilling.ecy)
• Predrill contour pocket 2 (SysMillContourPreDrilling.ecy)
• Tool change
• Mill contour pocket 1 (= SysMillContourPocket.ecy)
• Mill contour pocket 2 (= SysMillContourPocket.ecy)
