摘要
五轴联动数控机床由于两个旋转轴的存在使得插补后获得的刀具轨迹与理论编程轨迹不相等,存在非常大的非线性误差。通过对运动学坐标变换、双摆头五轴联动机床刀具运动原理和插补原理进行分析得出引起非线性误差的原因。介绍一种基于时间分割法的插补算法,通过MATLAB进行仿真实验及参数分析,其结果表明了该算法的有效性。
Due to the existence of the two rotation axes,actual tool path obtained by interpolation deviates from theory programming line,resulting in a great non-linear error.Through the study of kinematics analysis of coordinate transformation,the principle of tool motion and interpolation of five-axis machine tool with double pendulum head,the causes of nonlinear error were obtained.A interpolation algorithm based on time division method was introduced.The simulation experiment and parameter analysis based on MATLAB were carried out.The results show that the algorithm is effective.
