Abstract
Austenitic stainless steels are generally regarded as more difficult to machine than carbon or low alloy steels, because they are strongly workhardened. They bond very strongly to the tool during cutting, and this bonding is more obvious than when cutting other steels because the chips more often remain stuck to the tool after cutting. And when the chip is broken away it also remove other fragments. In this thesis, the machinability of the Ca-S free-cutting stainless steel and its relation with compound inclusions are studied. The tool wear mechanisms and tool wear progression patterns are identified. The cutting tool temperature field for machining Ca-S free-cutting stainless steel is modelled using the MSC/NASTRAN finite element analysis software package.
