Study of the Assembly Motion for a Virtual Assembly System

This paper describes the virtual assembly automation systems, as decision support systems, for the better knowledge of assembly operation. The study of this procedure is described as well as the necessity for assembly systems design. The work draws on research into product and manufacturing knowledge models. In this paper, the authors have proposed a virtual prototype model for assembly system architecture of robotic assembly automation. This paper presents a methodology for solid modeling in a virtual environment that is precisely performed in an intuitive manner through constraint-based manipulations Constraint-based manipulations are realized by allowable motions for precise 3D interactions in the virtual environment. A mathematical matrix is presented for representing allowable motions. A procedure-based degree-of-freedom combination method for 3D constraint solving is presented for deriving the allowable motions from constraints. A prototype system has been implemented to testify the feasibility of the presented methodology.
