Hi all, with my limited experience on my lathe, I now want to expand into milling where I know nothing. After ruining a HSS end mill cutter, I just bought a 50mm Face End Mill Cutter with 4 carbide inserts and tried milling the bottom face of my AXA holder that sits too high on my toolpost. My initial results are no good, so after some googling I realize there are RPM, feeding and other parameters that need to be correct. I also found some 'formulas' but I cant can't make anything from them Can someone please suggest the correct RPM and other parameters? Thanks ahead for any help!
