Abstract
The data model of machine tools plays a key role to share and manage machine tools information among modern manufacturing systems and has been considered as a fundamental basis for achieving various manufacturing activities such as process planning, machining simulation and production scheduling. Although research into modelling machine tools has been done, these modelling approaches are either machine vendor specific, or limited and incomplete in their scope to represent machine tools. Therefore, a comprehensive and generic machine tools data model (CGMTDM) is proposed in this paper. The proposed data model is constructed based on the oriented-object EXPRESS language, which not only includes the information of mechanical elements, but the information of the electro-mechanical and electronic elements. The case study is used to demonstrate the proposed data model at the end. It has been concluded that CGMTDM can consistently, completely and flexibly represent the information of machine tools.
