Question:
Assume the milling process takes “y + 3” minutes for gold and “y” minutes for steel, Your milling department will need to process 500 watch cases, whereof 80 yellow gold cases and “15 * y” pink gold cases. The mill uses a different cutting tool for steel than for gold, and the changeover takes 15 minutes. Between each material change the mill must be cleaned and the sward must be collected for recycling. This takes an additional 10 minutes. Calculate for how much time your milling department is occupied with this job of 500 items. Determine the throughput of the mill for gold cases, disregarding the cleaning and tooling procedures.
