Titanium and its alloys are hard to machine. Titanium, with its density of 4.5g/cm^3,which is 60% of that of steel, is an excellent anti-corrosion material rich in heat-resisting quality. It is, however, expensive and liable to chemical reactions under certain conditions. The writers of this report has tried to see, through a series of experiments, how titanium is affected by Hot-machining and arrived at the following conclusion. 1) As to its cutting resistance : Usually materials show lower cutting resistance after Hot-machining, while titanium shows greater cutting resistance after being machined in a excessively high temperature. 2) As to the degree of the chipping of the cutting edge : Chipping of ceramic tools is excessive when used in a high temperature. 3) As to its surface roughness : The surface roughness of titanium remains unimproved even when it is machined under different conditions.
