Characterization Method and Evaluation System of Surface Integrity in Precision Machining

Article Preview

Abstract:

The importance of the surface integrity in modern machining is represented. Based on the notion of the surface integrity that was put forward by Michael Field, a new method of surface integrity characterization is presented in this paper. This method consists of surface quality, surficial coat quality and the edge quality. Then an evaluation system of surface integrity based metrology is constructed and has been applied in a machining process of nickel-base alloy turbine disk. The manufacturing time decreased by approximately 10%. In all, this characterization and the evaluation system of surface integrity are rational and efficient. This work let us be capable of breaking through in the systematical evaluation of present machining surface.
