6.22 Pattern Machining
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 of drilling/milling operation
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: Pattern distance (Cartesian coordinates)
Ji end point: Pattern distance (Cartesian coordinates)
R length: Distance between first and last position
Ri length: Distance to next position
Q number of holes/figures (default: 1)
Parameter combinations for defining the starting point and the
pattern positions:
Starting point of pattern:
XK, YK
X, C
Pattern positions:
I, J and Q
Ii, Ji and Q
R, A and Q
Ri, Ai and Q
