- A process currently services an average of 59 customers per day. Observations in recent weeks show that its utilization is about 90 percent, allowing for just a 10 percent capacity cushion. If demand is expected to be 70 percent of the current level in five years and management wants to have a capacity cushion of just 4 percent, what capacity requirement should be planned? The needed capacity requirement is nothing customers per day. (Enter your response rounded up to the next whole number.)arrow_forward5. Types of Shaper Machines and their outputs in engineering industry.arrow_forward(a) An engineer would like to drill a square hole of 20 mm x 20 mm with depth of 25 mm on a layered structure of natural fibre-reinforced polymer composite. He encountered delamination problem in the workpiece (Figure 3) when he used conventional cutting tool to drill the hole. Instead of using conventional machining process, discuss ONE suitable advanced machining process that can be applied for this machining purpose and predict TWO possible limitations for the selected process.

- 1. Die casting is the process where molten metal is force into the die cavity at high pressures. There are two types of die casting; hot camber process and cold chamber process. Please describe and draw the schematic illustration to represent each of them. 2. a) Flat rolling reduces the thickness of plates and sheets. It is possible, instead, to reduce their thickness simply by stretching the material? Would this be a feasible process? Explain. b) Defects may be present on the surfaces of rolled plates and sheets, or there may be internal structural defects. Defects are undesirable not only because they adversely affect surface appearance, but also because they may affect strength, formability, and other manufacturing characteristics of the rolled sheets. Describes the typical defects in flat rolling by providing the schematic illustration for each of them.arrow_forwardWhat are the major classes of manufacturing processes?
