Estimate the manufacturing cost for a simple machined component: a. Compare the costs for manufacturing volumes of 1, 10, 100, 1000, and 10,000 pieces with an intermediate tolerance and surface finish. Explain why there is a great change between 1 and 10 and a small change between 1000 and 10,000 pieces. b. Compare the costs for fit, intermediate, and rough tolerances with a volume of 100 pieces. c. Compare the costs of manufacturing the component out of various materials.
A high-speed steel tool is used to turn a steel workpart that is 295 mm long and 75 mm in diameter. The parameters in the Taylor equation are: n = 0.15 and C = 80 (m/min) for a feed of 0.5 mm/rev. The operator and machine tool rate = $29.00/hr, and the tooling cost per cutting edge = $3.90. It takes 2.1 min to load and unload the workpart and 3.40 min to change tools. Determine (a) cutting speed for maximum production rate, (b) tool life in min of cutting, and (c) cycle time and cost per unit of product (d) cutting speed for minimum cost and tool life in min of cutting
