Load it in the machine and time the part of the cycle where sparks are actually happening to process it from start to finish. Remove the finished part and weigh it again. Make your calculation : weight removed /Density = volume removed. Volume removed /time = MRR. Unless I fucked up one of the formulas, that should do it. Cheers Marcus
