305 STEPを用いた工作機械の構造・形状統合モデルの提案とその5軸加工への応用(OS-5 生産システムとCAD・CAM)

Abstract

In machining process using multi-axes CNC machine tools, the kinematic model and the shape model for the machine tools are necessary to generate NC data and to simulate the motion of machine tools. However, in such case, both models are not integrated into one machine tools model, and some problems have arisen. For example, some NC data contain interference between a cutting tool and the elements of the machine tools in NC generation process, and the relations between kinematic model and geometric model of machine tools should be created whenever the NC simulations are performed. In this study, an integrated model to connect kinematic model with shape model for machine tools based on STEP (ISO 10303) is proposed. Also, to verify the proposed model has enough information for machining, the integrated model for 5-axis machine tools is generated, the motion data are generated and the motion of machine tools is simulated by using this generated model.
