 G799 Thread milling (direct position input): Page 306
Pattern definitions:
 G743 Linear pattern on face for drilling and milling cycles: Page 302
 G744 Linear pattern on lateral surface for drilling and milling
cycles: Page 304
 G745 Circular pattern on face for drilling and milling
cycles: Page 303
 G746 Circular pattern on lateral surface for drilling and milling
cycles: Page 305
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 197
