6.22 Pattern Machining
Linear pattern, face G743
With cycle G743, you can machine linear hole patterns or figure
patterns in which the individual features are arranged at a regular
spacing on the face.
If "ZE" has not been defined, the drilling/milling cycle of the next NC
block is used as a reference. Using this principle, you can combine
pattern definitions with
Drilling cycles (G71, G74, G36)
The milling cycle for a linear slot (G791)
The contour milling cycle with "independent contour" (G793)
Parameters
XK starting point
of pattern (Cartesian coordinates)
YK starting point
of pattern (Cartesian coordinates)
Z starting point
of drilling/milling operation
ZE end point

X diameter
(polar coordinates)
C starting angle
(polar coordinates)
A pattern angle
I end point
of pattern (Cartesian coordinates)
J end point
of pattern (Cartesian coordinates)
Ii end point:
