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
