hey guys..
I am trying to cut stencils on my mill.. i setup a flat area, 400mmx400mm and affix the plastic sheeting to the acrylic table with double sided tape.
everythign works great but i am having nightmares finding cutters and speds that will work ok.
I tried a profile cutter, a pyramid and ever a tapered ballend, all with the same result, a rough melted edge. My spindle cannot go slower than 5K RPM and i cannot chase faster than 780mm/min for now.
the cuts are very shallow, 0.55mm to 0.65mm max so i set it to cut through to about 0.8mm since under the plastic sheeting is just more acrylic anyhow.
I tried "up" cutting and "down" and up yielded better results.
Is anyone else here cutting plastic sheet that can give em a poke in the right directions.
Attaching gcode im trying to cut. The stencil is to be used for spray painting. this is jsut a sample design.
maybe i need to be looking at a drag cutter rather than a cuttintg tool in the spindle?
