基于OpenGL的數(shù)控仿真三維圖形的研究：數(shù)控加工過程由數(shù)控程序控制，但數(shù)控程序的錯(cuò)誤往往不容易被發(fā)現(xiàn)。從而在實(shí)際加工中可能出現(xiàn)碰撞干涉等問題。通過數(shù)控仿真軟件可以在制造之前在計(jì)算機(jī)中模擬加工過程，發(fā)現(xiàn)可能出現(xiàn)的碰撞、干涉，零件的可加工性及工藝的合理性等。而在虛擬加工環(huán)境下，三維圖形處理是其核心的技術(shù)問題。本文以三維圖形軟件標(biāo)準(zhǔn)OpenGL 為工具，探討數(shù)控仿真系統(tǒng)中三維圖形的處理方法。
Abstract：The process of Computer Numerical Control (CNC) machining is controlled by the
program of CNC, but the faults of the program of CNC is often difficult to be found. So there are
possibly many problems, like collision, interference and so on in the real machining. We can
simulate machining process by the software of CNC simulator in computer before the real
machining, then find possible collision, interference, the machinability of parts and the
reasonability of process, and so on. The process of 3 dimension graphics is a main technical
problem. This paper mainly discuss the process of 3 D graphics by VC++ and OpenGL.
