Hi all,
cnc millling process
I am making parts from 1045 steel (10RC). the part has a groove of 0.078 wide and .157 deep. I am using 4 flute coated 1/16 end mill. MACHINING DATA
RMP-5700
IPM- 7
DEPTH OF CUT-.025

There are two problems please give me advice on that.
1. Tool wears off and break exactly after 10 pieces.
2. the cycle time is about 11 min.

This increases set up time and tool cost.

Is there any differnt method should i use? feed and speed? Different type of tool? Depth of cut?

Please give me advice

Thanks
