车削多面体运动的矢量建模及误差分析

摘要:

通过矢量分析，选择了车削多面体运动的标架，建立了车削多面体运动的矢量模型，在此基础上给出了描述车削多面体运动的矢量表达式，建立了相对运动的矢量公式和刀尖轨迹的矢量公式。通过几何分析，建立了加工表面的直线度公式。实验验证了车削多面体运动的矢量表达式和加工表面的直线度公式。

Abstract:

The coordinate system of turning polyhedron movement was selected and its vector model was established by way of analyzing the vector, and based on that, the vector expression of describing turning polyhedron movement was deduced, then the vector formula of the relative movement and the vector formula of the path of the lathe tool were built. The formula of straightness error of the machined surface was also founded through geometrical analysis. At last, the above formulas were testified through an experiment.
