HEIDENHAIN CNC PILOT 4290 51
4.1.2
Contours
in
the
XY
Plane
(Front
and
Back)
Circular hole pattern, circular figure pattern
Parameters
XM(X), YM(Y): Center in Cartesian coordinates (XM radius
dimension)
PM, α : Center of pattern in polar coordinates (reference angle α :
positive X axis)
Q: Number of figures
Orientation:
■ Clockwise
■ Counterclockwise
Special cases:
■ Without α or β : Full-circle subdivision, beginning at 0°
■ Without β : Full-circle subdivision
K: Pattern diameter or radius
α( A): Starting angle – position of the first figure (reference: X axis)
β (W): Ending angle – position of the last figure (reference: X axis)
β i(Wi): Distance between holes/figures
For figures, except for circles, you must enter the ”position of the
figure” in the figure description:
■ Normal position (H=0): Initial figure is rotated about the
center of the pattern.
■ Original position (H=1): Position of the figure remains the
same (translation).
Hole description/figure description
In patterns with circular slots, the ”center of curvature”
is added to the pattern position (see User's Manual,
section ” 4.7.11 Circular Pattern with Circular Slots”).
