6.22 Pattern Machining
Circular pattern, face G745
With cycle G745, you can machine hole patterns or figure patterns in
which the individual features are arranged at a regular spacing in a
circle or circular arc 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 center of pattern (Cartesian coordinates)
YK center of pattern (Cartesian coordinates)
Z starting point of drilling/milling operation
ZE end point of drilling/milling operation
X diameter (polar coordinates)
C angle (polar coordinates)
K diameter: Pattern diameter—default: The current X position is
transferred.
A starting angle—position of the first hole/figure
W end angle—position of the last hole/figure
Wi end angle—distance to the next position
Q number of holes/figures (default: 1)
V direction of rotation (default: 0): Position of holes/figures
(required if W is defined):
V=0: Holes are placed on the longer arc.
V=1: Holes are arranged clockwise, starting at A.
V=2: Holes are arranged counterclockwise, starting at A.
Parameter combinations for defining the center of the pattern and
the pattern positions:
Center of pattern:
X, C
XK, YK
Pattern positions:
A, W and Q
A, Wi and Q
