Abstract


Precision ball screw is a key feature of the CNC machine tools , its spiral has a large impact on the accuracy of the positioning accuracy of CNC machine tools . The topic combined projects three meters , laser ball screw dynamic measuring instrument technological innovation \The first measurement method to determine the dynamic measurement method ; formulation of an overall transformation program and then according to the current situation of the measuring instrument . Measuring instrument as a measurement with high precision circular grating angle reference , Renishaw ML10 laser as the length of the measurement reference , plus temperature compensation system to design compensatory measures constitute the overall program . Meet the measurement requirements in accordance with national error evaluation standard , the preparation of the screw spiral , human-computer interaction and friendly measurement software , and adapt them to the development trend of automation , intelligent . Test instrument accuracy of the measuring instrument to analyze the formation of the reasons for the error of the measuring instrument , ready for the next step to improve instrument precision . Technological transformation of three meters measuring instrument , subject to the completion of the actual value .
