工作機械の精度設計に対する解析的アプローチ : 創成運動誤差に伴う加工面の誤差の解析

抄録

This paper deals with a machine tool design system based on a mathematical model of the shape generation process, aimed at establishing a systematic design methodology for new machine tools taking consideration of machining accuracy. In particular, emphasis is given to analysis of geometric errors on product surfaces due to kinematic errors of shape generating motions between tools and workpieces. The main topics are as follows: (1) the establishment of a mathematical model of shape generating motions of machine tools with kinematic errors; and (2) the estimation of geometric errors on product surfaces due to the kinematic errors in shape generating motions.
