【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.更多还原
