The customer would like the round shafts to be reduced to a thickness of 1.5”. The milling machine has a tool that is 4” in diameter with 20 teeth. The maximum depth of each cut is .2” per pass. Assume that you have a cutting speed of 560 F.P.M. Also for every ten teeth on your cutting tool .075” is removed.Determine the following:1. Spindle speed in RPM2. Chip Load or cut per tooth3. Feed-rate in inches per minute4. Number of passes required to meet specs.5. Material Removal Rate in Cubic Inches Per Minute.
