Cutting spline/gear in Y axis Mill/Turn lathe

DEREK_MARKLY73A — Thu, 21 Aug 2025 12:04:02 GMT

I am having a hard time figuring out exactly how to do this in Fusion. I have a custom tool made that is the same geometry as the spline on this hub, and I need to program it to be able to work on a Y axis mill/turn Lathe.

I have attached the file that is the closest I have gotten on it, I dont know if I need to draw additional geometry to pick up the correct point or what needs to happen here.

The custom tool should be in the toolpath that I left in the attached .F3D file.

I was planning to use a circular pattern of the tool path in order to cut the rest of the teeth, but I dont know if there is a better way to do that as well.

Thanks in advance.

Not sure if the file attached properly the first time. Here is the part/toolpath that I have gotten so far with the custom tool.

This solution worked correctly. I had a feeling it was going to be something like this but could not find a reference to how to do it without doing some trial and error. Thank you again.
