摘　　要：针对圆环刀具切触加工自由曲面,提出了一种新的基于动力学过程的多点切触刀位算法,该算法主要来自于柔顺自适应刀具吻合曲面的动力学和运动学过程.从分析圆环曲面的几何性质入手,结合动力学观点,分析自适应圆环刀具运动规律.采用MATLAB编写算法程序对自由开阔模具曲面多点切触刀位数据进行计算,并对刀位误差及加工带宽作了简要分析,最后利用ADAMS进行仿真验证,结果与计算方法吻合.A new tool positioning algorithm of toroidal cutter multi-point contact for processing curvic surface is proposed.The principle of the algorithms is originated from the dynamics and kinematics related in the processing.Based on the analysis of the geometry property of torus and the character of self-adaptive tool system,the tool positioning algorithm model is established.A self-adaptive toroidal tool system is designed,and a dynamics process in ADAMS is simulated to process the positioning data.The results are compared between using ADAMS and MATLAB and the algorithm program correctness and effectiveness are verified,the results coincide with the calculation method.
