How does the R value need to be calculated. It says it is the number of divisions which I assume is passes. Lets say I have to remove .06 on a casting and I want to do .020 per pass. Do I put in three passes (R3) and it will still leave my finish allowance? Or do I have to calculate it to leave my finish stock? Example .012 finish 3 roughing passes at .016 and a (R3) for 3 passes to add up to my .060? Appreciate any help. Thanks
