Research on Robot Machining Path Planning Technology for NURBS Surface

This paper studies the surface machining path representation based on NURBS and its key technologies of path planning, analyzes the advantages and disadvantages of various path planning algorithms for NURBS surfaces, and finds that the current NURBS surface machining path planning algorithms mainly consider geometric constraints, while There is less correlation analysis on the index of machined surface roughness, so it is necessary to combine intelligent algorithms and other technologies in the future to better solve practical engineering problems. Path planning algorithms are evaluated.
