Overview of drilling and boring cycles and
contour reference
The drilling and boring cycles can be used with driven or stationary
tools.
Drilling and boring cycles:
 G71 Simple drilling: page 313
 G72 Boring/countersinking (only with contour reference (ID,
NS): page 315
 G73 Tapping (not with G743–G746): page 322
 G74 Deep-hole drilling: page 319
 G36 Tapping—single path (direct position input): page 318
 G799 Thread milling (direct position input): page 326
Pattern definitions:
 G743 Linear pattern on face for drilling and milling cycles: page 322
 G744 Linear pattern on lateral surface for drilling and milling
cycles: page 324
 G745 Circular pattern on face for drilling and milling
cycles: page 323
 G746 Circular pattern on lateral surface for drilling and milling
cycles: page 325
Possibilities of defining a contour reference:
 Path definition directly in the cycle.
 Reference to a hole or pattern definition in the contour section (ID,
NS) for machining on the front face or lateral surface.
 Centric hole in the turning contour (G49): page 210
 Pattern definition in the block before the cycle call (G743 - G746)
