Abstract: In order to verify the error compensation effect of NC(numerical control) XY worktable under the influencing multiple factors,it is necessary to design a measurement and control system that can realize real-time acquisition and synchronous trigger of temperature,motion speed,X/Y coordinate position and standard quantity for compensation experiment verification.The measurement and control system that can realize the synchronous triggering and real-time acquisition of the worktable motion speed,temperature,grating scale and inductance micrometer is introduced.The numerical control XY worktable is taken as the research object,the inductance micrometer is used as the displacement standard of the worktable,DSP is used as the main control chip,and the experimental device is built for real-time acquisition,synchronous trigger and comparison experiments，measurement error and measuring repeatability error experiments.The experimental results show that the designed measurement and control system can achieve the preset target,which can realize the comparison between the displacement of the numerical control XY worktable and the standard quantity under different influencing factors,and verifying the error compensation effect of XY worktable.The researched results can be lay a foundation for the future error compensator researching of the CNC on-machine measurement systems.
