Machining 4142 Profile
I'm machining a small part from 1/8 thick 4142 with a 1/4" diameter 2 flute carbide(cheap) end mill and it eats the corners off the mill. My last attempt was 1800 rpm, 1.0 IPM, .025" DOC and it's a full width cut as I'm cutting the part from a piece of stock. Any ideas on different feeds and speeds?
I just ran ME Consultant again it says 2000 rpm, 4 IPM and I know it won't do that.
I'm running dry as I have no flood coolant.
Thanks
John
