Odd Shaped Bore Holes

[ALSjosh]

Houseman- I do have a spring pass or a finishing contour applied to the bores and I am leaving .005 axial and radial and coming back with finishing tool paths on all other movements

But you don't have radius compensation enabled in Fusion. When I looked at your G Code from Fusion I couldn't find G41 or G42. If you use radius compensation, you can adjust the diameter of the tool in Cnc12 and simply run the finishing program again if, for example, a pocket is too small.

Would it be a good idea to enable smoothing for this in CNC12?

yes, G64 should always be on when outputting line segments. This is also the case with real processing machines when you work with cam programs. I can force G2/3 output in Solidcam for profile and pocket jobs, but not for adaptive or 3D jobs.

Fusion can output G2/3 on any toolpath and I prefer it over short vector stuff...

Please post an adaptive program where only G2/3 occurs or a 3D job with Z constant.

Uwe, I answered the question myself and your statement about G2/3 is not really true.

There will never be only G2/3, only when a radius is in the toolpath or on the model, splines will be with short vectors.

....a HTD3 Belt is zero backlash.....

It's not a problem in this case but I found otherwise. The pulley stock often seems to be produced in China, then machined into pulleys closer to home. I was unable to obtain pulleys that didn't cause backlash due to the poor tooth profile, despite creating a lovely collection of pulleys from various different suppliers.


In the end I had to make my own pulley.

It's because each different tooth count pulley requires a different tooth profile. This is not a problem if the pulleys are hobbed, but if they are cut one tooth at a time with a profile cutter, it can be. Manufacturers try to save money by using the same tooth profile on a "family" of pulleys.

adaptive bore most lines with G3...
