Optimizing a Machining Operation Productivity in manufacturing partially depends on how efficiently individual machining tasks are performed. The total production cycle time Te for a single part consists of three components: . Th is the pt handlng time needed to load and unload the part in the machine; .Tm is the actual machining time for the part; and T, is the tool change time, which is allocated over the number N of pieces machined during one tool life. If T represents tool life, N T, The machining time for drilling a hole of diameter D and depth d is T, where fis fv the feed rate (distance per revolution) and V is the actual cutting speed of the outer edge of the dril bit. Cutting speed is related to tool life by the Taylor tool life equation VT Ctools operated at high speeds wear out and must be replaced more frequently. The constants n and C must be empirically determined for each individual operation. (a) Use the Taylor tool life equation and the formulas for N and T to rewrite Te as a function of cutting speed Valong with constants Th, T, D, d.,, n, and C. (Be especially careful with exponents theyll get kind of strange here.) (b) The maximum production rate will result from minimizing the production cycle time. Find a formula for the cutting speed that will minimize production cycle time. (c) Suppose that, for drilling holes in an aluminum alloy using a high-speed steel drill bit, t has been found experimentally that n = 0, 15 and C = 350 ft/min. If it takes 1.0 minutes to replace a worn drill bit, what cutting speed (in ft/min) will minimize total production cycle time
