Use Cycle 21 PILOT DRILLING if you machine a contour and then use a tool for roughing it out which has no center-cut end mill (ISO 1641). This cycle drills a hole in the area that will be roughed out later with a cycle such as Cycle 22. Cycle 21 takes the finishing allowance for side and the finishing allowance for floor as well as the radius of the rough-out tool into account for the cutter infeed points. The cutter infeed points also serve as starting points for roughing.

Q10 Plunging depth? Tool infeed per cut (minus sign for negative machining direction). This value has an incremental effect. Input: –99999.9999...+99999.9999 | |
Q11 Feed rate for plunging? Tool traversing speed in mm/min during plunging Input: 0...99999.9999 or FAUTO, FU, FZ | |
Q13 or QS13 Rough-out tool number/name? Number or name of the rough-out tool. You are able to transfer the tool directly from the tool table via the selection option in the action bar. Input: 0...999999.9 or max. 255 characters |
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
