Cut with my 4 Axis setup and quickly cleaned up for burrs.

I like it, but haven’t got a clue what good it does.

May be it will be used for grinding something in the kitchen.

I’m just kidding, it’s a sample cut and it ends up in a drawer and is probably thrown away in about 10 years from now.

Time to grind a gear and treat it like a worm gear. :slight_smile:

Looks like i have some catching up to do.

@Kyle_Kerr or trying mill the NUt for these leadscrew :wink:

@Kyle_Kerr that’s cool. I think I’ll try that. I think i need to make another of these properly. But it could be really fun to make a wooden worm gear.

This one is cut all wrong for a thread or gear. But surely it can be done.

  • Henrik Larsen rather than a typical gear, maybe a round with holes drilled to accept small dowels that would slip in and out of the grooves? However, it would probably just be easier to use something like inkscape to generate a usable profile for a gear and mill that on the 4th axis as well.

For a well functioning worm gear the teeth should be slanted i think. Don’t remember the exact wording.

@brian_alley you need to look at their forums for 4 axis postprocessor. The ADF360 postprocessor, is the CNC machine specific program, that converts design into gcode. The postprocessor you use now, needs to be copied and edited. It’s about simply enabling the 4th axis by changing one ‘false’ word to ‘true’ and one ‘true’ to ‘false’. Then you can create cam operations, where you set tool orientation. When you postprocess a design with tool orientations enabled, with the new postprocessor, it will write A turns between CAM operations. ‘NYC CNC’ made a video on youtube on the subject. https://youtu.be/bUxLrsonUrM
