Description
Face B on the swivel plane
Z coordinate of the reference point (abs)
X coordinate of the reference point (abs)
Y coordinate of the reference point (abs)
Starting angle: Angle of 1st hole with reference to X axis.
Positive angle: Full circle is rotated counterclockwise.
Negative angle: Full circle is rotated in clockwise direction.
Indexing angle: After the first hole has been drilled, all additional positions are
approached at this angle (only for pitch circle).
Positive angle: Additional positions are rotated in counterclockwise direction.
Negative angle: Additional positions are rotated in clockwise direction.
Radius of full circle
Number of positions on circle
Straight line: Next position is approached linearly in rapid traverse.
Circular: Next position is approached along a circular path at the feedrate defined
in the machine data.
