Operation Manual

HEIDENHAIN CNC PILOT 640 459
5.14 Contours in the XY plane
Circular pattern in XY plane
Reference data: (siehe „Reference data in XY plane” auf Seite 446)
You can find the reference dimension ZR and the limit diameter IR
with the "select reference plane" function (siehe Seite 425).
ICP generates:
 The FACE_Y section code with the parameters limit diameter,
reference dimension and spindle angle. The section code is omitted
for nested contours.
 A G308 with the parameters contour name and milling depth or hole
depth (–1*BT).
 A G472 with the parameters of the pattern.
 The G function and the parameters of the figure/hole.
 A G309.
Reference data in XY plane
ID Contour name

ZR Reference dimension
Parameters of pattern
X, Y Center of pattern
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 position—the figures are rotated about the
circle center (rotation)
 1: Original position—the position of the figures
relative to the coordinate system remains unchanged
