With a total of two patents to his name, his work focuses on error measurement and compensation systems that enhance the precision and reliability of CNC machinery.
Latest Patents
Wei Han's latest patents include an "Online CNC machine tool geometric/thermal error measurement and compensation system." This system is designed to address the technical challenges of error testing and compensation in CNC machine tools. It comprises a hardware platform that includes a unidirectional acceleration sensor, a precision integrated circuit (IC) temperature sensor, a multi-channel temperature data collector, and a geometric/thermal error measurement and compensation host. The accompanying software runs on the host to facilitate the testing and compensation of geometric and thermal errors, which are communicated to the FANUC CNC system.
Another significant patent is the "Spindle thermal error compensation method insensitive to cooling system disturbance." This method aims to mitigate the impact of cooling system disturbances on spindle thermal errors. The process begins with a spindle model coefficient identification test based on variable speeds. Following this, a correlation analysis is conducted to identify the temperature measurement point that is significantly correlated with the axial thermal error of the spindle. A thermal error model is then established, which is robust against cooling system disturbances. The model's coefficients are identified using a nonlinear quadratic programming algorithm, and the compensation values are communicated to the numerical control system via the OPC UA communication protocol.
