Terry, yes, that would be the root radius. Sorry for the confusion, but always had the hexagon in mind while doing this and assumed it was obvious. I will have to give it a bit more thought to make it multipass. Don't want it to cut air at any point.

Russ, I agree, squares may not be practical, but I believe hexagons and above should be doable in metals provided the rake angle is correct. We shall see this. Now I really think eccentrics should be next... what do you say, Terry?

Hmm... didn't notice the metal hex sneaked in - obviously they have some better ways to make hex shapes out there... Grin

Wonder if we can make this as the next stage:

Terry, I think I confused you again. I was not using the flat length (chord length), but rather the distance across the flats - what you actually measure with a caliper across flats. You can call it the inscribed circle diameter otherwise.

Thanks Terry. Reason I did it with the distance across flats is that usually that would be the known parameter as dictated by standard wrench sizes. I can see though where the shaft diameter would be rather convenient. Anyway not a problem to derive one from another. What I do like in your approach is, as I mentioned, the option to do this in multiple passes.

Yes, the math with arcs is going to be painful. Interesting how it will work out.

What noise do you mean? Two sounds are there - one of the X stepper and the other of the A axis which has very high acceleration and hence you here it as knocks. Material is delrin.

Thanks Ya-Nvr-No.

Terry, thanks to your idea of utilizing the toolpath display I was able to debug the code and now have a perfect working version. It works very well. With my approach the minimal number of flats is 3. See attached final code. I have also cleaned it up a bit and added some more comments for readability. Works very well here and I am pleased.

Here is a short video showing it in action:

Took less than a minute to cut this.

By the way. Changed my code to work in degrees mode so that toolpath would display more meaningfully. See attached. It didn't occur to me previously, but this way the debugging is easier. Interestingly the toolpath produced by my code consists of almost straight lines, while yours of curved lines. So based on the fact that mine did produce flats somehow, I would assume that there is a problem with yours  Huh.

Ah.. I see now what you mean. Cutting the shape in multiple passes. This is more powerful than my approach. And you code looks much simpler too Wink Not that I figured the math though.

True. Do you have a link to the Honeywell switches? What type are they and what accuracy?
