精度保証加工のための加工誤差要因の推定に関する研究

―工作物把持による加工誤差への影響評価―

抄録

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.
