4.11 Programming Examples
Example: Thread milling
The drill hole coordinates are stored in the point
table TAB1.PNT and are called by the TNC with
CYCL CALL PAT.
The tool radii are selected so that all work steps
can be seen in the test graphics.

Questions and answers
Can I change the approach direction when cycle def a stud to avoid obstruction to the right
The provided context does not explicitly mention changing the approach direction to avoid obstruction. However, it describes selecting different axis configurations using the MOD function in the Programming and Editing mode. If modifying the axis configuration allows for adjusting the approach direction, it may be possible. Otherwise, specific cycle parameters should be checked in the programming manual.
