I am looking for suggestions for the best way to use Rhino to generate a planar curve (toolpath) that loops on itself guiding a CNC milling tool forward to cut a straight slot using rotating motions. Example:
As a feasibility test, I approximated this path with a tilted helix projected to the Cplane:
This path slipped nicely into my CAM plugin and generated Gcode nicely:
To finesse this, I am now looking for suggestions as to the best way to approach a practical process that would let me (a) specify/control the Y width value of the loop, (b) stepover X value between lobes and © modify the back of the return curve to shorten the non-cutting travel time so my output 2D tool path better resembles the first example … while keeping the entire output as a single curve…
My inexperience with the many different, advanced Rhino options has me humbly seeking higher pay-grade guidance :^)
All thoughts and suggestions welcome.
