Research on Solid Modeling Technology Based on Virtual Simulation Machining

Computer simulation is a kind of experiment technology by utilizing the computer software to simulate real world. With the development of computer hardware and software and virtual reality technology, computer simulation is widely used in the manufacturing industry. In this paper the principle and the algorithm of solid modeling by virtual simulation machining are introduced. Taking the gear and the worm as examples, we describe some key technologies of virtual machining modeling, including design of the user interface, construction of the tool and the blank models and the process of virtual machining. All examples are implemented in the environment of ObjectARX language and Visual LISP language for AutoCAD secondary development. Finally some advantages and disadvantages of virtual machining modeling by these two kinds of development languages are analyzed. Some suggestions are put forward in order to create accurate 3D solid models.
