NativeCAM + trochoidal milling? was created by robertspark
hi, I was wondering if there was any chance of adding trochoidal milling to NativeCAM?
as an aide to those us us with more light weight setups?
I have estlcam and remain impressed with it, although it is only available under Windows (not tried it but apparently can be made to run under wine), but NativeCAM is really useful for which operations such as generic facing, profiling and pockets and arrays etc.

Just some thoughts:
Not in a CAM but implement in hal:
1. use cutter compensation.
2. the tool-table diameter is cutter plus "oscillation" amplitude
3. use external offset in x and y with amplitude
4. Use a siggen for frequency
Wouldn't this would be a nice G-code

I am a noob at linuxcnc... still learning the nomenclature (more putting it all together / how to add events from other inputs than the nomenclature)...
I've got a very lightweight router (openbuilds c-beam XL) and trochoidal milling helps to avoid high cutting forces. ok the delrin nuts suffer additional wear and more frequent replacement but got to break eggs to make an omelette.... and it's all a trade off.... sure I'd like a large format hobbing router able to do occasional aluminium... but not in my garage as a hobbyist.
trochoidal milling also opens up the possibility of using a lightweight 4'x4' plasma table for router work too in my opinion (not tried it (yet!))

Hi robertspark,
you can find plenty of algorithms in the internet for this topic, trochoidal/adaptive pockets, circles, etc. Weird shapes are still a thing for a CAM but regular shapes like rectangles, circles, or dogbones (ref. to your other question) can be handled by an algortihm not to complicated.
Bringing it to NativeCAM is the 2nd part of the job, the 1st one would be to write a GCode/OCode which does the operation, using parameters like start/stop coordinates, size, speeds, etc.
If you can achive part 1 I will gladly add the operation to the NativeCAM ui.
Regards,
Daniel

thanks very much, happy for a bit of homework.
NativeCAM is a really nice and helpful tool for simple operations and a really big timesaver.
