Material removal rate formulafor milling

A Reddit for Machinists of all varieties. From Old School conventional guys, to CNC Programmers, to the up and coming next generation.

Hello machinists. I'm doing some calculations on material removal rate (MRR). I have zero experience with CAM software, so I wrote a script in Solidworks that simulates an endmill's movement through a workpiece at a small time interval. That way I could calculate the material loss for each time step. This is obviously not a neat way of approaching this problem. Are you guys aware of any CAM software that is capable of calculating MRR? Thanks!
