Parameter Description
Axes Selection of the participating axes
● XY (1st and 2nd axis of the plane)
● XA (1st rotary axis and assigned linear axis)
● YB (2nd rotary axis and assigned linear axis)
Note:
Rotary axes are only displayed in the selection field if they have been released for use
in the position pattern.
Please observe the information provided by your machine manufacturer.
Z0 Z coordinate of the reference point
Axes XY (at right angles)
X0 X coordinate of the reference point X (abs)
Y0 Y coordinate of the reference point Y (abs)
α0 Starting angle for first position.
Positive angle: Full circle is rotated counter-clockwise.
Negative angle: Full circle is rotated in clockwise direction.
α1 Advance angle
After the first hole has been drilled, all further positions are advanced by this angle.
Positive angle: Further positions are rotated counter-clockwise.
Negative angle: Further positions are rotated clockwise.
Radius
R
Number of positions
N
Positioning motion between the positions
Positioning
● Straight line
Next position is approached linearly in rapid traverse.
● Circle
Next position is approached along a circular path at the feedrate defined in the
machine data.
