The 'heat map' of the graph spans MRR rates from 2.71 up to 3.3 MRR. That's a pretty wide range and I want to be heavy roughing (high MRR), so I press Calculate a few more times to gather more results. The low-end MRR climbs up to 3.31 while the high end creeps up to 3.39.Rambaudi Milling Machines - Lathes.ukIdentical in specification and size apart from their vertical heads, the V2 and V3 had just one size of table, 42" x 12", with four 9/16" T-slots on 2.5" spacing.
