Are the tools used in machining metals and non - metals (ceramics and polymers) the same? Explain.
The selection of tool depends on many factors, the one factor is harness of materials. The hardness of tool must be greater than the hardness of work piece. If the hardness of tool is less than the hardness of work piece then machining can not be done. Since the hardness of ceramics is more than the hardness of metals.
Therefore, the tools used for machining of metals and non-metals are different.
Are the tools used in machining metals and non - metals (ceramics and polymers) the same? Explain.
1: A: Ceramics Name two mechanical properties that make ceramics good candidates as cutting tools. B: Polymers What kind of bond is most often present to bond mers into polymers? What are the two measures used to characterize how big the polymer chains are in a given sample? Explain the three/four structures polymers can form as the molecules grow. Name the structure Explain the mechanical properties the polymer exhibits relative to the other structures

Which of the non-traditional machining tools would wear over time and require replacement (assuming normal operation condition): (a) ultrasonic machining, (b) electrochemical machining, (c) electric discharge machining, (d) wire electric discharge machining, (e) plasma arc cutting, (f) water jetting.
5. Explain why the stress-strain behaviors of metals measured in a tensile test cannot fully describe true stress-strain behaviors of materials. 6. Why the three point bending test is used to measure the mechanical properties of ceramics? Will the mechanical properties of ceramics be geometry dependent? 7. What is the crystallinity of polymer materials? How this structure gives rise to the unique mechanical properties of polymers? 8. For fibre-reinforced composites, will the material get totally failure after the fracture strain...
