Abstract

Abstract:

A DEXELoriented method for the implementation of workpiece modeling is proposed , thus greatly reducing the needed memory, and supporting the observed changes in perspective , realizing the zooming operations.According to the properities of 3aix machining,the cutter swept volume is made of discrete swept volumes and the discrete lattice method is carried out. The local hunting algorithm is presented to find out the set of points and revise the zvalue of workpiece.Under VC++6.0 and OpenGL,the method is realized and the test shows that it improves the quality of NCsimulation.

Key words: NC simulation;DEXEL model;cutter swept volume;discrete lattice;local hunting
