6.6 C-Axis Contours
In patterns with circular slots, the “center
of curvature“ is added to the pattern
position (see User’s Manual, “
4.5.8
Circular Pattern with Circular Slots“).
If you do not program the end point, the
holes/figures will be distributed evenly
along the circumference.
L: Total length of pattern
Li: Distance between the figures (pattern distance)
β:
Angle to the longitudinal axis of the pattern (reference: Z
axis)
W: Ending angle
Wi: Distance between the figures as angle (pattern distance)
Hole description/figure description
Circular Hole Pattern, Circular Figure Pattern
Parameters
Z: Center of pattern
CY: Center of pattern—angle as linear value
C: Center of pattern—angle
Q: Number of holes/figures—default: 1
Orientation:
■ Clockwise n
■ Counterclockwise
R: Pattern radius
K: Pattern diameter
A, W: Starting angle, end angle—position of first/last figure
(reference: XK axis)—special cases:
■ Without A and W: Full-circle subdivision, beginning with
0°
■ Without W: Full-circle subdivision
Wi: Angle between two figures (algebraic sign has no effect)
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).
