Design of Interactive Virtual Assembly Simulation System for CNC Machine Tool

Virtual assembly simulation system plays a vital role in the intelligent manufacturing, especially in the field of complex machine or product manufacturing. The designing defects or product drawbacks could be identified in the designing period using the virtual assembly system. In this paper, the virtual simulation model of three-axis CNC machine was developed using virtual simulation software, interactive virtual assembly function was realized based on menu button, people can make assembly for the machine in the system, through the menu button, the interactive assembly could come true. Then using coarse-to-fine collision detection method and the face-level precision inspection to obtain assembly constraints, using a bounding box method for rough detection. The specific detection process was discussed in detail. The interactive virtual assembly simulation system was established and verified at last, it has great meaning for complex product machining.
