Technology of NC Machine Error Parameter Identification Based on 22 Displacement Measurement Line

The geometric error detection and distinguishing technology is an important technology in errors compensation of numerical controlled machine tool. This paper introduced 22 displacement measurement line and the 22 lines of the principles of measurement for a more in-depth discussions and studies, the identification process for 21 errors existing in the machine tool is performed with the help of the 22 lines method. Finally a brief application of the 22 lines measurements of the line notes.
