X parallel — Select this option to arrange the drilling operations parallel to the X axis.
Y parallel — Select this option to arrange the drilling operations parallel to the Y axis.
Parallel angle — Optionally enter an angle in degrees. You can have the toolpath at any angle. The angle is measured counter-clockwise from the X axis if X parallel is selected or counter-clockwise from the Y axis if Y parallel is selected.
Honeycomb pattern
Plunge roughing is performed in either a straight rectangular pattern, as shown below:
or a honeycomb pattern in which each row is offset horizontally by half the rough pass stepover amount:
The honeycomb pattern is usually preferable. The Honeycomb pattern attribute controls the pattern type.
