Estimation of machining error factor for accuracy assured machining

-Assessment of workholding methods to machining accuracy-

Abstract

The objective of this research is to estimate machining error factors by using on-machine shape measurement. In the most conventional machining researches, it has been considered a cutting tool deflection as a dominant factor of the machining error. Only few researches mentions the influence of workholding. This research experimentally investigates the influence of workholding by comparing measured surfaces that are fixed by different workholding methods: mechanical vise and clump system. Furthermore, measured accuracies of machined parts are assessed based on the deformation trend of each fixturing method.
