Program sequence
■
The contour of the ellipse is approximated by
many short lines (defined in Q7). The more
calculating steps you define for the lines, the
smoother the curve becomes.
■
The machining direction can be altered by
changing the entries for the starting and end
angles in the plane:
Clockwise machining direction:
starting angle > end angle
Counterclockwise machining direction:
starting angle < end angle
■
The tool radius is not taken into account.
