8.5 Cycles for Machining Hole
Patterns
Overview
The TNC provides two cycles for machining hole patterns directly:
You can combine Cycle G220 and Cycle G221 with the following fixed
cycles:
Cycle Soft key
G220 CIRCULAR PATTERN
G221 LINEAR PATTERN
If you have to machine irregular hole patterns, use
G79 “PAT”
to develop point tables (see “Point Tables” on
page 226).
Cycle G74 SLOT MILLING
Cycle G75/G76 POCKET MILLING
Cycle G77/G78 CIRCULAR POCKET MILLING
Cycle G83 PECKING
Cycle G84 TAPPING with a floating tap holder
Cycle G85 RIGID TAPPING without a floating tap holder
Cycle G86 THREAD CUTTING
Cycle G200 DRILLING
Cycle G201 REAMING
Cycle G202 BORING
Cycle G203 UNIVERSAL DRILLING
Cycle G204 BACK BORING
Cycle G205 UNIVERSAL PECKING
Cycle G206 TAPPING NEW with a floating tap holder
Cycle G207 RIGID TAPPING NEW without a floating tap holder
Cycle G208 BORE MILLING
Cycle G209 TAPPING WITH CHIP BREAKING
Cycle G212 POCKET FINISHING
Cycle G213 STUD FINISHING
Cycle G214 CIRCULAR POCKET FINISHING
Cycle G215 CIRCULAR STUD FINISHING
Cycle G251 RECTANGULAR POCKET
Cycle G252 CIRCULAR POCKET MILLING
