The design is still being finalized, but I thought I would share…
The first hurdle is complete. I’ve run some test cuts in PVC. This was with a 1/8" 2 flute end mill. 30ipm. Three different DOC’s .04", .05", and .06".
I’m thinking I can steel get some more speed out of due to the sound of the bit. It doesn’t look like the plastic melted at any of these speeds. What you see melting on top is the plastic protective cover.
What do you think?
