EMAE 160 - L8 Questions with complete Solutions

What is the RPM equation? - Answer-RPM=(12*cutting speed)/(π*tool diameter) What is the feed rate equation? - Answer-feed rate=RPM*flutes*chip per tooth Describe broaching and provide an example of its application. - Answer-A broach has teeth that go from rough to fine that picks away at metal. It can be used to create a square keyway. A cutting edge that can hold up under high temperatures experienced at the chip-tool interface possesses a quality called what? - Answer-Hot Hardening What...

What is the purpose of a flat washer? Correct Answer-To distribute the pressure of the nut/bolt evenly over the part being secured, reducing the chance of damage, and to provide a smooth surface for the nut/bolt to bear on, making it less likely to loosen as a result of an uneven fastening surface. (A flat washer sits between a bolt and joint material (not bonded) and allows for optimum load distribution.) Why do we coat metals? Correct Answer-to provide corrosion protection, provide a speci...

True or false: Resistance welding processes make use of the heat generated by electrical resistance to achieve fusion of the parts to be joined; no pressure is used. Correct Answer-False True or false: Weld failures always occur in the fusion zone of the weld joint, since this is the part of the joint that has been melted. Correct Answer-False, occur in heat welding zones Which of the following arc welding processes uses a non-consumable electrode a. SMAW b. GMAW c. FCAW d. GTAW Correc...

List three differences between thermoset plastics and thermoplastics. Correct Answer-Thermoplastics are solids that become malleable when heat above a certain temperature. Thermosets are not malleable once hardened. Thermosets are stronger than thermoplastics, but thermosets are also more brittle. Structure of polymer: linear linked vs. cross linked Pultrusion is most similar to which of the following plastic shaping processes? Correct Answer-Extrusion Which of the three polymer types does...
