Cutting Rubber
(OP)
Could someone help me out I'm trying to cut 90 durometer rubber. The geometry is OD of 1.5x .5 long step down to OD 1.375 x .5 long with 2 (.5 dia) x .5 deep flat bottom holes on it. tolerance is +/- .015. All dims in inches. I tried sharp turn tool, sharp endmills, fast, slow. Is grinding feasable? Any help would be appreciated.

Is this a one off or a production job?
If one off, use a high rake angle tools(check definitions in Machinery's Handbook). High rake should peel this like an apple but the higher the rake, the less the edge life.
If high production, you may want to look at having the part cast to net size.

Thank you for correcting my rake angle zero reference!
