5. A soft cast iron block, 30 mm thick, 100 mm wide and 100 mm long is to be reduced to 25-mm-thick by removing material from each side, two holes, one 25 mm in diameter and the second 10 mm in diameter, are to be drilled as indicated in Figure 2. A carbide face milling cutter (125 mm diameter and having 6 teeth) and High speed steel drill are to be used for the operations. Assume the total pretravel and over travel distance for drilling is 1.5 mm. A vertical axis milling machine and a sensitive drill press are used for machining. A vice is used to hold the parts in both operations. What feed, cutting speed, and depth of cut should be used for each of the milling cuts? What feed and cutting speed should be used for each of the holes to be drilled? Estimate the cutting time for the milling operation, then estimate the total allowed time/piece for the milling operation. Estimate the cutting time for the drilling for both holes, then estimate the total allowed time/piece for the drilling operation. Estimate the allowed setup time for the milling and for the drilling operations. If a lot of 60 parts are made, what is the allowed time to produce the lot of parts?
