I am surface milling a helical flute using 4 axis and the only options for tool paths are type_1, which is back and forth (conventional and climb milling) and then there is an option for type_one_direction which starts at the front and mills back the flute, retracts and starts at the front again for the next path. Does anyone know if you can stay in the cut conventional milling, almost like a race track moving from the outside of the cut in? Is there a mold milling package or any other package that could do this if the surface milling cannot?
This is a piece of cake. Create a mill surface, put small hole in middle of surface, Create 4-axis surface milling sequence, using cutline, closed loops, use little hole edge as inner loop and outside perimeter edge as outer loop, then spiral or helical from outer to inner or inner to outer.
