Example: Curl Down Radius and Curl Over Radius
The figures in this example show a single retract of a tool path acting upon a horizontal surface, with different curls. The cutter rapids over the job from left to right, and sweeps down to make the cut from right to left in each case.
CURL DOWN and CURL OVER = 2
CURL OVER = 6 and CURL DOWN = 2
CURL OVER = 2 and CURL DOWN = 6
