I'm cutting 1/8" sheet making some auto-parts with a lot of through holes. The issue I'm running into is a disc of aluminum getting stuck to the bottom (cutting edge) of the bit, so after it retracts and moves to the next hole, it has to puuuuush then POPs through the material like a punch instead of cutting into it. It happens using either 2 or 3 flute HSS or coated carbide. It happens even when I use a .3" or .5" ramp. I am using a 2 head fogbuster, sometimes it blows the disc off before the next hole, but its about 50/50. I'm running ~200IPM @ 18k and ~35IPM plunge.
Any advice or can anybody explain what is happening?
Thanks for your help,
