a.) In a drilling operation, 3 blind holes needs to be drilled to a depth of 16 mm and a diameter of 8 mm. The point angle is 105° and the drill is made from HSS material. The bench drill allows a fixed speed of 1400 RPM and a feed of 0.1 mm per rev. The work part is mild steel with a thickness of 22 mm. Determine the time required to complete this operation. b.) What are some factors that determine the type of industrial cleaning that will be applied to a part?
