Small endmill

[Alain Maltais]

Hello guys,

 

I need to cut a die with a small endmill. I bought a .047" x .050" of cut endmill from harvey tool. #31047-C6

 

Im gonna cut low carbon steel on a router machine. I can run from 18 000 - 24 000 rpm ( or below 18k too)

 

Anyone could suggestion me RPM and feed. I was thiking of 24000rpm and 4.8 "/min. And probably .005-.010" depth of cut with ramping about 3/8" depth total?

 

Time is not a issues, I just dont wanna burn that tool tool. Im will be using blowing air alot.

 

 

Thanks

I would drop your depth of cut to .001 or to no more than .003. I would try to find some feed/speed info at the tool manufacturer's web site or look at a competitor's site that has a similar size tool. I think you should max the rpms but you need to keep a correct chip per tooth feed rate.
