Problems solved by technology

[0003] At present, the research on the kinematic characteristics of CNC machine tools is not deep enough. The existing systems applied to the accuracy detection of CNC machine tools are limited to the single-axis positioning accuracy test of machine tools (laser interferometer) or the circular motion test of machine tools (ballbar). They are all based on external sensors and require high installation conditions
