Circular pattern in XY plane
Reference data of XY plane:
ID: Contour
PT: Milling depth
C: Spindle angle
IR: Limit diameter
ZR: Reference dimension
Parameters of pattern:
X, Y: 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 the selected figure/hole
You can use the Select reference plane function to determine the
Reference dimension ZR and the Limit diameter IR.

ICP generates the following:
The FRONT Y section code with the Limit diameter, Reference
dimension, 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 G472 with the parameters of the pattern
The G code and the parameters of the figure/hole
A G309
