Research on the Cutting Force Induced Error Measurement Method of the CNC Machine Tools

The cutting force induced error has been more important as the hard cutting and hard cutting material used. This paper proposed the direct measurement method of cutting force induced error, which realized the corresponding directly of the cutting force and the value of error in the working process. According to the discrimination of machine error characteristics reflected by the different measuring methods, it puts forward to building the mixed error model based on the measuring technology of one dimension and two dimension. The results could provides the test data and theoretical basis for the mechanism of the processing performance affected by the dynamic behavior of machine tools.
