Hi all,
I'm trying to machine a 2.5mm piece of O1 tool steel with a 2 flute carbide, uncoated, 1/8" shank, 1/32" square OSG endmill. The part has a gradual slope so the depth of cut ranges from 1mm to 2.5mm. I am trying to mill a bunch of narrow and long slots but the tool only makes it about an inch until it breaks. So far I have tried feeding it at 10k rpm, 2 ipm with a 0.0001 ipt, and 1 ipm with a 0.00005 ipt with no success. It is a full width of cut and full depth of cut 2D contour toolpath, but I have not made it consistently past the 1mm section. I am using a Tormach PCNC 770 with flood coolant. I am aware that spindle speed is a limiting factor and don't have a speeder or similar yet.
I was wondering if it is possible to run this at a full depth of cut or should I be using multiple depths of cut? I was also wondering if my feeds and speeds are appropriate or terrible?
Thank you in advance
