선박가공에 의한 진원도 가공형상의 모델링에 관한 연구

Abstract

In this paper, a modeling of machined geometry was established for the case of round shape machining, and the effects of externally machined profile analyzed and its realiability was verified by the experiments of roundness, especially in lathe operation. In this study, harmonic geometric model was proposed with the parameter harmonic function. In general, we can calculate the theoretical roundness profile with arbitrary multilobe. But in real experiments, only 2-6 lobe profile was measured. The most freguently measured ones are 3 and 5 lobe profile in experiments. With these results, we can predict that these results may be applied to round shape machining such as drilling, boring, ball screw and cylindrical grinding operation with the same method.
