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 325
 G72 Boring/countersinking (only with contour reference (ID,
NS): Page 327
 G73 Tapping (not with G743 - G746): Page 334
 G74 Deep-hole drilling: Page 331
 G36 Tapping—single path (direct position input): Page 330
 G799 Thread milling (direct position input): Page 338
Pattern definitions:
 G743 Linear pattern on face for drilling and milling cycles: Page 334
 G744 Linear pattern on lateral surface for drilling and milling
cycles: Page 336
 G745 Circular pattern on face for drilling and milling
cycles: Page 335
 G746 Circular pattern on lateral surface for drilling and milling
cycles: Page 337
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 219
 Pattern definition in the block before the cycle call (G743 - G746)
