I am trying to get the toolpath for cutting an 80% lower for myself. I have the model in Fusion but just can't understand why using a 3/8 endmill wont generate a toolbath but if i go smaller it will. The pocket should let a 3/8" cutter in. Id there anybody that has done this can help me get started.


THANKS!

What type tool path are you using? Depending on the tool path it could be a % stepover issue.

i am using a 2d adaptive to cut the FGC pocket.

I think you want to reduce the helical ramp diameter, but I don't use that tool path often so I'm not 100%.

Yes, as above: it's most likely a helical ramp down diameter or a lead-in issue of some type. Just drill a hole a bit over 3/8", and as deep as possible as far forward in the well as possible, and then plunge down dead center in that hole and start machining from there.

Thanks will try that...

You can download a g-code for it from here:

It doesn't do a helical ramp, but rather ramps on the perimeter runs. Worked fine for me.
