8.5 Cycles for Machining Point
Patterns
Overview
The TNC provides two cycles for machining point patterns directly:
You can combine Cycle G220 and Cycle G221 with the following fixed
cycles:
Cycle Soft key Page
G220 CIRCULAR PATTERN Page 390
G221 LINEAR PATTERN Page 392
If you have to machine irregular point patterns, use
G79 “PAT”
to develop point tables (see “Point Tables” on
page 304).
