"Bolt Hole Circle" Oem-Cycle Example - HEIDENHAIN TNC 415 Technical Manual

4 "Bolt hole circle" OEM-cycle example

The following "Bolt hole circle" program is an example of an OEM-cycle. (This cycle has not been
loaded in the control unit!)
The Z-axis acts as the tool axis. The first hole in the circle is at 0 o . The OEM-cycle calculates the
angular position of the holes from the number of holes. The drilling positions are approached in
succession in an anti-clockwise direction, and the holes are made automatically with an in-feed.
Before the cycle is called, the tool is held at the safety clearance.
