Hi Art,

The clearance setting it was. Apparently was not understanding its purpose.

Thanks a lot!

Dan

Still doesn't work for me here. If a smaller diameter tool is selected it doesn't touch the tooth. If a larger tool selected it cuts through the tooth. See attached screenshots please.

Hi Art,

No problem. Will wait your return. Have a good time.

I checked the tool setting as it was the first thing I suspected.

Dan

Hi Art,

The simulation seems to be matching the final result on the 4th axis.

I can see the simulation being wrong. The tool cuts through the teeth in simulation or doesn't touch the teeth if too small in diameter.

Dan

Hi Art,

Using a cutter smaller than the suggested max. The tool actually doesn't touch the tooth - so the toolpath generated is farther apart from the tooth than the tool's radius. The only way I seem to be able to get tangent is by defining a smaller tool, then it generates the tool path and then ...

Thanks for explaining it Art and for the fix. And Kit, thanks for the drawing.

I just measured the thickness of a GT2-2 belt and it is around 0.5mm.

Art, did you also address the tooth profile error?

Dan

Art,

Does it mean that I was wrong treating the "outside diameter" shown by Gearotic as the pulley blank diameter?

Dan

Great! Thanks Art!

Dan

Used the DXF output from Gearotic to produce the profile of the tool which I then used to turn the tool on the lathe. My lathe is fitted with a servo motor on the spindle, so I indexed the blank and cut the teeth. The process works very well! See attached photos.

Here is a short video of the ...

Thanks Art!
