3.6 UNIVERSAL DRILLING
(Cycle 203, DIN/ISO: G203)
Cycle run
1 The TNC positions the tool in the spindle axis at rapid traverse FMAX
to the entered setup clearance above the workpiece surface.
2 The tool drills to the first plunging depth at the programmed feed
rate F.
3 If you have programmed chip breaking, the tool then retracts by
the entered retraction value. If you are working without chip
breaking, the tool retracts at the retraction feed rate to the setup
clearance, remains there—if programmed—for the entered dwell
time, and advances again at FMAX to the setup clearance above the
first PLUNGING DEPTH.
4 The tool then advances with another infeed at the programmed
feed rate. If programmed, the plunging depth is decreased after
each infeed by the decrement.
5 The TNC repeats this process (2 to 4) until the programmed total
hole depth is reached.
6 The tool remains at the hole bottom—if programmed—for the
entered dwell time to cut free, and then retracts to the setup
clearance at the retraction feed rate. If programmed, the tool
moves to the 2nd setup clearance at FMAX.

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.
