Hi, I am trying to cut some alluminium sheet, which is 0.457mm thick with a 2 flute 1mm carbonised cutter, have tired using settings of 24000 rpm with a feed rate of 400mm/min and plunge rate of 300mm/min, and also 19000 rpm with the same feed and plunge rate however the cutter keeps breaking. I can't use a bigger cutter as the items that I'm cutting are quite intricate.... If anyone can suggest any other ideas it would be much appreciated.
Thanx
