Nov 07 2015 thanks to this thread i finally have some ball end mills coming it has been long over due for cutting any material if you could run the spindle slow enough or the feed rate fast enough to get a decent chip load on a cnc machine tapered ball nose questions post by dhellew2 sat nov 07 2015 642 pm
Read MoreAug 15 2011 i am curious what other experienced machinist use to determine an end mill depth of cut for example i use the 2x longer then 2 square 2x2 rule that is a end mill sticking out 2 times longer then 14 depth of cut i ordered 12 end mill with 125 loc but received 1625 length of cut formula says with aluminum and hss end mill
