I'm trying to cut UHMW with a 1/8 cutter. This is the first time I'm trying to cut this material. It's not too bad but the top of the part is far from clean cut.
I'm cutting it with a brand new 1/8 2 flute carbide cutter DOC is .125 4400RPM , 40IPM lot's of coolant. I started from 25IPM and gradually increased the feed while 4400RPM remained constant.
I don't dare to push it further I hate breaking tools...
My Mill is a Tormach max IPM65 max RPM 4500
Thanks,
James
