Mold code

[Monafly]

Would it be feasible to add an output option to generate G-code for a mold for the desired gear instead of the gear itself?

Thanks.

Hi:

   No, I dont think thats feasable. Moulding requires a full 3d Gcode program be put out, but there are so many ways and options in doing that , that it requires a full 3d cam program. SO while the 3d model could be used by such a cam program to create the mould, its out of the scope of a small(?) utility program like Gearotic Motion to do such a thing.

Maybe a full mold is out of the question, but what about code to cut a 'stencil' instead of the gear. For a simple spur gear (or any of them) this would cut the inside of a sheet leaving the gear pattern as a hole. Think of puzzle pieces-the gear and a gear shaped hole that fit together. It would be same as cutting the gear with an infinitel y thin cutter with no lead ins etc. This would be as 2D, not using a rotary axis.

Thanks.

hmm, that would probably work now just by doing a 2d cut with a .000001mm diamter tool..

Opps-a minimal diameter cutter would make the example I cited, but I want to cut the stencil with a real cutter but end up with a gear shaped hole. For a spur gear this would be the equivalen t of making an internal gear and can be done at present for spurs, but not for any of the others. Maybe would be a better way to make the request-allow eccentric and imaginary 'internal' gears to be made and cut with real sized cutters.

Thanks.

Hi:

  Hmm, internals I dont think would work well, but eccentric s would. Unfortuna tly the method of eccentric generatio n I use is a osculatin g circle method, to really do an eccentric that can be internal ring geared I need to use a constant pressure angle algorithm . I plan on developin g such a beast after I get a few more things done, including the bevel gears.
