Linear pattern, lateral surface G744
With cycle G744, you can machine linear hole patterns or figure
patterns in which the individual features are arranged at a regular
spacing on the lateral surface.
Parameter combinations for defining the starting point and the pattern
positions:
„ Starting point of pattern: Z and C
„ Pattern positions:
„ W and Q
„ Wi and Q
If XE has not been defined, the drilling/milling cycle or the figure
definition of the next NC block is used as a reference. Using this
principle, you can combine pattern definitions with drilling cycles (G71,
G74, G36) or milling cycles (figure definitions with G314, G315, G317).
Parameters
 Z starting point (polar coordinates)
 C starting angle (polar coordinates)
 X starting point of drilling/milling operation (diameter value)
 XE end point of drilling/milling operation (diameter value)
 ZE end point of pattern (default: Z)
 W end angle of pattern—no input: Holes/figures are arranged on the
lateral surface at regular spacing
 Wi end angle: Angle increment—distance to next position
 Q number of holes/figures (default: 1)
