The positioning errors detection and compensation of translational axes for five-axis measuring system based on VDI-3441 criterion
In order to improve the positioning accuracy of translational axes for five-axis measuring system,the laser interferometer was used to detect the positioning errors in the closed-loop motion control mode.The positioning error curve of three motion axis was achieved by the approach of spline interpolation.In the meanwhile,the positioning errors were compensated by the way of modifying the indicating values of linear gratings.The VDI-3441 criterion was utilized to evaluate the positioning accuracy of such system before and after compensation.The experiment results illustrate the positioning accuracy has been significantly enhanced after compensation.
