15+40N >= 240 + 2N => N = 6 Hence for Order sizes 6 or preceding(preno secondal) CNC should be used and order sizes under 6, manual press should be used CNC Routing Let number of Orders = N pickup clip for punch press = 50 + N clock for CNC Router = one hundred fifty + 0.5N Again, CNC router should be used scarcely if 50 + N > cl + 0.5N * N = 200 Capacity of DFPR theater of operations area (Order size sour to be 8) Time taken for panel preparation (one panel has eight circuit boards, t here(predicate)from 8 orders is serviced by a single panel preparation) = 5 + 0.2 = 5.2 min Time taken for Lamination and exposure = 20 + 2 = 22 min Time taken for Developing = 20 + 0.2 = 20.2 min Hence the blockade work on here is Lamination and exposure which takes 22 min for an order size of 8. Hence capacity of this process = 1/22 panels per minute = 60/22 panels per hour = 2.72 panels...If you want to bug out a proficient essay, order it on our website: Ordercustompaper.com
