Design and Implementation of a High-speed Data Acquisition and Analysis System for Robot Grinding and Polishing Force Position

In the process of grinding the surface of complex curved parts, simply controlling the position of the robot cannot ensure the consistency of the grinding removal amount, which is easy to lead to the phenomenon of over-grinding and under-grinding. Aiming at the above problems, this paper designed a high-speed data acquisition and analysis system for robot grinding and polishing force position based on ARM+FPGA, including hardware circuit design and software system implementation. The system could control the contact force in real time and monitor the distance between the grinding tool and the surface of the part. The experiments show that the system can effectively improve the precision and quality of surface grinding of complex curved parts. Its functions and performance in high-speed acquisition and data interaction can meet the consistent requirements of surface grinding removal of curved parts.
