摘要
本文以典型的具有两个旋转轴的正交五轴联动机床为例,利用机构运动学原理建立了一种机床的通用运动学模型,即：四个正交旋转轴和三个正交平移轴。通过齐次变换矩阵和正、逆运动学分析,得到了NC数据的完整的表达式,实现了刀位数据CL和NC数据之间的相互转换,为相应数控机床的刀位数据后置处理程序的开发提供了统一的空间坐标变换基础。
Taking the typical orthogonal five- axis machine tools with two rotary axes as an example, this paper establishes a universal kinematic model by using mechanism theory; a model has four orthogonal rotating axes and three orthogonal translational axes. The complete analytical equations for NC date are obtained through homogeneous coordinate transformation matrix and the analysis of forward and inverse kinematics, and thus the interconversion between machine tools＇ cutter location（CL） and NC date is realized by using the derived equations,to provide a unified space coordinate transformation basis for the development of relevant machine tools＇ CL postprocessing program.
