4.22 Drilling cycles

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
Further information:
G72 Boring/cnt-sink (only with contour reference (ID, NS)
Further information:
G73 Tapping (not with G743 – G746)
Further information:
G74 Deep-hole drilling
Further information:
G36 Tapping – single path (direct position input)
Further information:
G799 Thread milling (direct position input)
Further information:
Pattern definitions:
G743 Pattern linear face for drilling and milling cycles
Further information:
Page 383
G744 Pattern linear surf for drilling and milling cycles
Further information:
Page 387
G745 Pattern circ. face for drilling and milling cycles
Further information:
Page 385
G746 Pattern circ. surf. for drilling and milling cycles
Further information:
Page 389
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)
Further information:
Pattern definition in the block before the cycle call (G743 - G746)
