Cutting Simulation With Computer Based on Refection Meshes

This paper presents an algorithm of cutting simulation based on rectangular reflection meshes.After rectangle meshes are constructed on the projected plane of the machined surface,the height function of each element is built to express machined surface by appreciating the experience of thin plate element in finite element method.The heights and the slopes of the nodes are used in building the element function,and the intersection algorithm is still one dimension operation.The method is proved with high efficiency and high precision also.
