ICP programming | Contours in the YZ plane
Hole in YZ plane
This function defines a single hole that can contain the following
elements:
Centering
Hole
Cavity
Thread
Reference data of hole:
ID: Contour
C: Spindle angle
XR: Reference diameter
Parameters of hole:
YM, ZM: Center
Centering
O: Diameter
Hole
B: Diameter
BT: Depth (without algebraic sign)
W: Angle
Cavity
R: Diameter
U: Depth
E: Sink angle
Thread
GD: Diameter
GT: Depth
K: Cut-in length
F: Thread pitch
GA: Thread direction
0: Right-hand thread
1: Left-hand thread
You can use the Select reference plane function to determine the
Reference diameter XR.

and Spindle angle parameters. The section code is omitted for
nested contours.
