摘　　要：应用空间圆弧和空间样条曲线两种规则曲线的插补算法,对多自由度磨料水射流喷嘴在笛卡尔坐标系中抛光异型陶瓷零件进行路径规划。通过建立理想状态下的微细磨料水射流射流束抛光数学模型,采用矢量法对复杂的运动轨迹利用圆弧和样条曲线来逼近,在MATLAB软件环境下建立了磨料水射流复杂曲面的抛光运动数学模型,并对其进行数值模拟。模拟结果表明,运动数学模型所得到的运动轨迹符合射流束抛光要求,从而证明了该模型的有效性和先进性,为深入研究微细磨料水射流抛光轨迹优化提供了重要的理论基础。The path planning of polishing special-shaped ceramic parts in a Cartesian coordinate system is carried out for multi-degree-of-freedom abrasive water jet nozzles.The interpolation algorithms of space arc and spatial spline curve for two regular curves are applied.The mathematical model of micro-abrasive-water-jet polishing under ideal condition is established.The complex trajectory is approximated as vectors by arc and spline curve.The mathematical model for polishing movement of abrasive water jet on complex surface is established and simulated in MATLAB software environment.The simulation results show that the motion trajectory obtained by the mathematical model meets the requirements of jet polishing,which proves the feasibility of the model and provides an important basis for further optimization study of micro abrasive water jet polishing trajectory.
