Circular pattern on face
You can find the reference dimension ZR with the "select reference
plane" function (see page 411).
ICP generates:
 The FRONT section code with the reference dimension parameter.
In nested contours, ICP generates only one section code.
 A G308 with the parameters contour name and milling depth (–
1*BT).
 A G402 with the parameters of the pattern.
 The G function and the parameters of the figure/hole.
 A G309.

Parameters of pattern
XK, YK
Center of pattern (Cartesian coordinates)
QP Number of points in pattern
DR Direction of rotation (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 Pattern diameter
AP Starting angle (default: 0°)
EP End angle (no entry: the pattern elements are equally
divided into 360°)
EPi Angle between two figures
H Element position
 0: Normal – the figures are rotated about the circle
center (rotation)
 1: Original position – the position of the figures relative
to the coordinate system remains unchanged
(translation)
Parameters of the selected figure/hole
