undamentals
6.1 Fundamentals
Overview
The TNC provides two cycles for machining point patterns directly:
You can combine Cycle 220 and Cycle 221 with the following fixed
cycles:
Cycle Soft key Page
220 POLAR PATTERN Page 161
221 CARTESIAN PATTERN Page 164
If you have to machine irregular point patterns, use CYCL
CALL PAT
(see "Point Tables" on page 54) to develop point
tables.
More regular point patterns are available with the PATTERN
DEF
function (see "Pattern Definition PATTERN DEF" on
page 46).
