Would it be difficult to port some of these features (like using letters instead of program numbers) to the default centroid turn post processor in the fusion's library? I'm scared of trying to program a new post myself.

Not sure I understand what you are asking. The base of my Post Processor is the Centroid Mill post processor from the Fusion Library so why would you want to port single features back to the one in the library rather than just using this one?

There's nothing you have to program yourself. You just copy the post processor (the .cps file) to a local folder on your Fusion 360 computer and in the Fusion 360 post processor menu you select that your post processor is "local" and then select the .cps file in the folder you have placed it in. That's it.

Post here if I did not understand you correctly or if you have more questions.

Hi swissi,
the centroid turn post is for the lathe, in short, I was hoping one could find a lathe post as good and with the same features as the "mill swissi" one.

Thanks for doing this, I tried using the post and unfortunately get an error in the machine path. I'm pretty new to CNC so I may have done something wrong either in Fusion or perhaps the post isn't posting out properly. The issue is instead of the cutter staying at Y0 (I'm running the Line rotary pass) and the A axis simply rotating to machine my part, A axis will rotate the specific angle and the Y axis will move as well. Any insight or help would be greatly appreciated.

I overlooked the word "Turn". If you just want to enable alphanumeric file names, this is a very simple change. Just open the file "centroid turning.cps"

You are not giving me anything to work with. You basically went to the doctor and told him "I'm not feeling well. What's wrong with me?"

First assume you are doing something wrong. If you think you found something that doesn't work right, you need to give all the details, including sharing the CAM model that's causing the problem, so I can reproduce the issue and try to fix it.

Beauty, thanks Swissi.

Hi Swissi,

Sorry for not giving you much, I'm struggling to explain. Here is a snapshot of the part in Fusion with the toolpath set to run a Line Rotary Pass back and forth along the X axis as the A Axis rotates. I've also included a picture of the resulting part that got half machined until I realized it wasn't machining it properly and I took it off the mill. You can see the scallop on the right of the image is where milling started and the geometry is correct but as the wheel rotates the scallops get progressively wider (because Y kept stepping over), to the point on the left where material was being removed with the side of the cutter because the Y position had moved over so much. I would have expected the endmill to simply stay at Y=0 and pass back an forth along X and A would rotate 1 degree after each pass. I've also included a snapshot of a bit of the code. I hope this is the right information to explain the issue.

Actually, now that I look at the Fusion part and the resulting part, none of the scallops are correct? The number of scallops don't match?

When you run "Simulate" in Fusion 360 with the Option "Stock" checked, does the part look correctly at the end?

If not there's a problem with your tool paths. If it does look correctly, share the model in Fusion 360 and post the share link here or email it to my email address listed below in my signature.

Hi Swissi,

The error has been resolved.. Completely user error, I forgot to select "Yes A Axis" in the post.. :-/
