Evaluation System of Assemblability in Bolt Feature -Stability of Laying and Handlability of Parts-

볼트 형상에 대한 조립용잇겅 평가 시스템 -볼트의 놓임안정성 및 취급용이성을 중심으로-

The assemblability was determined by the structure of product and the relationship between composing parts and machining parts. In this paper, the bolt was divided into bolt-head, -shaft, -thread and -end. For the better assemblability in bolting process, the geometric and technological characteristics of bolts in terms of pre- and in-assembly process were analyzed. And this paper presents assemblability evaluation for bolt feature design alternatives. For this evaluation system, we considered systematically eight factors for assemblability, but introduced two factores for the stability of laying and for the handlability of parts. And AutoCAC system is interfaced with the evaluation system written in C-language.
