In the thesis. reading the iges file - 3 - and all the geometry entities and annotation entities are extracted ; on the base of geometry entities extracted, geometry entities are classified based to their three views. a new data structure is proposed to describle 3d form features ; inspection items of the workpiece are recognized ; the cmm - based inspection planning system is built ; on the other hand, as a part of cims, cmm need exchanging data with the software of cad / cam, so iges export interface is developed based on iges standard. in order to show the whole information of the surface, the 3 - dimensional free - form surface is drawing using the opengl
通過讀取iges文件對實體進行分離、提取、識別出對工件進行描述的原始信息；在此基礎上，西安理工大學碩士學位論文提出一種優化演算法對三視圖自動進行分離，建立了一種對工件進行三維描述的數學模型，照此模型對工件進行立體重構；識別出工件的各種檢測信息，提出一種對公差信息進行描述的數學模型，井與三維立體相結合，生成有檢測意義的三維實體；根據三坐標機的測量系統，生成相應的檢測規劃；另一方面，作為cmis的一部分，應具有與cad cam軟體之間的數據交換功能，本文還開發了iges輸出介面，採用opengl繪制三維空間曲面，向用戶展示其全面信息。Measuring cylinder is used on test bench of fuel injection pump all over the world, so manufacture error, sight error etc make the accuracy degree low. the thesis analyses the problem of fuel measurement system of the test bench of fuel injection pump, and the experiments and designs are done according to the problem, and the type and situation of the test bench of fuel injection pump all over the world is refered to
目前國內外噴油泵試驗臺量油系統普遍採用量筒式計量法，該方法存在量筒的製造誤差、沉積誤差、液面讀數誤差、氣泡誤差、揮發誤差以及測量人員的視覺誤差等，使得測量精度較低、耗時長，已不能滿足對汽車發動機的環保技術要求和節能要求。
