1. A milling operation is to be performed on a ductile cast iron shaft to make slots for assembly. The operation will be done at high speeds for good surface finish. For each of the following tool materials, indicate whether it is a reasonable candidate to use in the operation with a detailed description of why or why not including required alloying element/grade/group etc. where applicable: ) plain carbon steel, (i) high-speed steel, (ii)cemented carbide, (iv) ceramic, and (v) Sintered polycrystalline diamond. After selection of material/materials discuss about ) recommended angles and tool signature (ii) how to held cutting edge, and type of cutting fluids With reasons for each recommended material.
