Metal Low Temperature Brittleness and Low Temperature Machining

Abstract:

Article Preview

Most metal materials tend to produce brittle fracture at low temperature. Nominal stress of producing brittle fracture is low, generally lower than yield limit. By use of this property, the machinability of the workpiece, tool life and workpiece surface quality can be improved. Classification and application of low temperature machining was introduced in the paper. Tests of low temperature machining were carried out. The test results show low temperature machining is superior to the cutting in normal temperature for the aspects of tool life and the roughness of workpiece surface.
