Overview
The TNC provides two cycles for machining point patterns directly:
Cycle
Soft key

220 POLAR PATTERN
221 CARTESIAN PATTERN
You can combine Cycle 220 and Cycle 221 with the following fixed
cycles:
If you have to machine irregular point patterns, use
CYCL CALL PAT(See "Point tables") to develop point
tables.
More regular point patterns are available with the
PATTERN DEF function (See "PATTERN DEF pattern
definition").
