Error Identification and Compensation with Space Gauge in High-Speed Machine Tools

The ever-increasing demands of very high precision components have forced manufacturers to improve equipment to meet the demand. The main factor is the identification and compensation of errors in machine tools. In this paper, a new real-time method is presented to identify and compensate the error with space gauge, by use of which the composition of errors is directly compensated by measuring the deformation of the points in machine bed. Then, a simple single-axis machine tool is used to determine the relationship of deformation between gauging point and control point to verify the feasibility of the method. Furthermore, due to the simplicity of the implement and, the method can be easily used in an industrial production with minimal investment. Consequently, the result shows the method can be widely applied.
