Research of Virtual Cutting Based on Hap Tic Feedback

As product design has entered the stage of green design, virtual design becomes increasingly important, and cutting research is the core of it. This paper established a basic virtual cutting system and the grid models of virtual objects based on PHANTOM Omni hap tic feedback device and its system development toolkit and built up oriented bounding box and operated bounding box collision detection. On the base of these, the paper also presented a new method of cutting force condition judgment of cutting tool, and gave the cutting path planning and grid model reconstruction on the basis of virtual cutting methods of triangular grid unit model. At last, the paper researched the virtual cutting of grid model using computer programming language, providing design methods for product design. The relative methods may advance the effect of product design drastically.
