目的研究基于Ｓｔｅｗａｒｔ机构的并联加工机的插补算法．方法利用通常的时间分割插补算法思想和并联加工机构逆运动学模型，求解刀具运动轨迹与６根伸缩杆之间的关系，导出一种插补算法，并采用面向对象的程序设计方法编制仿真软件，通过计算机仿真验证该插补算法的可用性．结果与结论对球面类和双曲面类零件加工过程仿真结果表明，所提出的插补算法是正确、实用的，为并联加工机提供一种新的可行的插补算法
Aim To study the interpolation algorithm of parallel machine based on Stewart mechanism. Methods Based on the idea of time-division interpolation algorithm and the inverse kinematics model of parallel machining mechanism, the relationship between the tool path and the six telescopic rods is solved. An interpolation algorithm is derived and an object-oriented programming method is used to prepare the simulation Software to verify the usability of the interpolation algorithm by computer simulation. Results and Conclusion The simulation results of spherical and hyperbolic parts machining process show that the proposed interpolation algorithm is correct and practical and provides a new feasible interpolation algorithm for parallel machines
