Circular pattern on lateral surface G746
With Cycle G746, you can machine drilling or figure patterns in which the
bore holes are arranged at a regular spacing on a circular arc on the
lateral surface. If you do not enter “XE“, the drilling/milling cycle or figure
description from the next NC block is used – drilling cycle G71, G74, G36
or figure G314, G315, G317 (milling).
Parameters
Z, C:
Midpoint, angle (midpoint of pattern in polar coordinates)
X, XE: Start point/final point for drilling and milling (diameter)
K: Pattern diameter
A, W: Starting/final angle
Wi: Angle increment – distance to next position
Q: Number of bore holes or figures – default: 1
V: Direction of rotation (input is necessary only if W is defined) –
default: 0
Location of the holes/figures:
• V=0: On the longer arc
• V=1: Clockwise, starting at A
• V=2: Counterclockwise, starting at A
