Please typing answer only IENG 302 - Manufacturing Processes: We are reducing the diameter of a 95.8 mm cylinder to 30.04 mm using 7 roughing passes and 3 finishing passes. The finishing operations use a depth of cut of 1.51 mm. The roughing operations are performed with a feed rate of 9.61 mm/s and the finishing operation is performed with a feed rate of 11.31 mm/s. a) What is the depth of cut for a roughing pass? b) What is the rate of material removal (mm^3/s) for the third roughing pass? c) What is the rate of material removal (mm^3/s) for the final finishing pass? d) What is the average rate of material removal (mm^3/s) for the roughing operations?
