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)
WARNING
If the sum of the number of contour elements of the edge contour and island contours is over 100, the cycle should not be executed if several channels are active.
