Circular pattern in YZ plane
Reference data of YZ plane:
ID: Contour
PT: Milling depth
C: Spindle angle
XR: Reference diameter
Parameters of pattern:
Y, Z: Center of pattern
QP: Quantity of points in pattern
DR: Dir.rot. (default: 0)
DR = 0, without EP: Figures are arranged on a full circle
DR = 0, with EP: Figures are arranged on the longer circular
arc
DR = 0, with EPi: The algebraic sign of EPi defines the
direction (EPi < 0: clockwise)
DR = 1, with EP: clockwise
DR = 1, with EPi: clockwise (algebraic sign of EPi has no
effect)
DR = 2, with EP: counterclockwise
DR = 2, with EPi: counterclockwise (algebraic sign of EPi has
no effect)
DP: Diameter
AP: Start angle (default: 0°)
EP: Final angle (no entry: the pattern elements are distributed
evenly around 360°)
EPi: Final angle – Angle between two figures
H: Element pos
0: Normal – The figures are rotated around the circle center
(rotation)
1: Master – The position of the figure relative to the
coordinate system remains unchanged (translation)
Parameters of selected figure or hole
You can use the Select reference plane function to determine the
Reference diameter XR.

ICP generates the following:
The SURFACE Y section code with the Reference diameter
and Spindle angle parameters. The section code is omitted for
nested contours.
a G308 with the Contour name and Milling depth or Boring
depth (–1*BT) parameters
A G482 with the parameters of the pattern
The G code and the parameters of the figure or hole
A G309
