ESTLCAM - Peel Milling through narrow area

Hi,

I am admittedly new to ESTLCAM. I have this part I’d like to make, and I can make it with an 1/8" endmill, but 5/32" would be a bit better. In theory it’s doable - the narrowest gap is 3/16".

When I increase my endmill radius to 5/32", it refuses to make the paths.

I think this is because ESTLCAM refuses to cut into the finishing pass with the roughing passes.

Any way around this?


Here’s what happens at 5/32".

Yeah, best not to peel if there is a narrow area.

How would you approach this?

To me a huge benefit of peel milling (I’m used to other CAM, so call it different things) is to be able to go through narrow sections without engaging the entirety of the cutting tool, especially important with a small cutter like this.

If there’s a different way to accomplish the same sort of motion with EstlCAM I’m eager to learn.

The 5/32" tool is too big, it causes path overlaps and cutting outside the line. A peel is going to be really slow, do a Preview and compare the estimated times for Peel and Linear. Also run the Preview to see how the rim gets cut, I’m thinking there will be full engagement there. The worse part of full engagement is the entry and ramping (Plunge angle 20-30) is highly recommended… Trochoidal milling (https://www.youtube.com/watch?v=ORJ-Q3TFW5o) probably only makes sense if the material is aluminum.

Yeah the overlap on the outside isn’t a problem. This is actually more what I wanted, I added the outer circle as an attempt to get the pathing working right:

(I realized I had the tooth count wrong, so can use a 5/32" endmill… still should be doable with a 3/16" endmill in this scenario though)
