The aim of this research work is to research how to rea1 ize that the geometry information and process information of the part is described and extracted whi 1e parametric feature part drawing is formed by means of feature mode1ing for revo1ving mode1 parts . features act as media to realize share and exchange for information between design and manufacture in order to fit the requirements for deve1opment of modern techno1ogy and rapid renewal of products 本课题研究工作目的是通过对回转体零件特征建模,研究在特征参数化设计生成零件图的同时实现描述、提取和输出零件几何信息和工艺信息的方法,以特征为载体实现设计与制造之间的信息共享与交换,以适应现代技术发展及产品快速更新的要求。
For solving all these problems , through applying visualization technology of engineer design to the design of oil - feed unit , this paper constructs the entity model of oil - feed unit , establish the three - dimensional standard parts , implement the semi - automated and automated connect , and produce automatically the 2d or 3d part drawings . using this system the designer can observe and evaluate the space model of the unit , discuss the feasibility of space layout and the probable errors , so that the decision can be optimized and the competition of enterprise can be improved greatly 针对船舶供油单元设计、制造中的上述问题,本系统拟将工程设计可视化技术应用于船舶供油单元的设计,构造船舶供油单元的三维实体模型,建立三维标准件库,实现管路的自动、半自动连接,自动生成管路的二维和三维零件图,使得设计人员在设计阶段就可观察、评判单元的空间模型,直观地探讨空间布置的合理性和存在的问题,从而帮助决策的优化,提高企业竞争力。
Then , this paper deeply studies the key technology of the cutting stock system for project manufacture enterprises : optimized cutting stock , graph disposal and system integration , etc . after analyzing the working flow of the column generation technology , brings forward the interpolation algorithm for solving non - guillotine cutting stock problem . image processing technologies including parts image processing and result image generating are studied 分析了优化下料算法? ?列生成法的求解流程,提出了插补求解二维non - guillotine切割的启发式算法;分析了图形处理技术,包括零件图预处理技术和结果图生成技术;提出了系统集成的方案,实现了优化下料技术与cad 、 capp 、 cam技术的有机集成。
Graphics software can take out the spare parts sketch from graphics database that is used an evidence for writing nc program . because the data information stream from designing part to writing nc program is continuous , it is in favor of cad / cam integration . it can simulate the relation between the cutter track and the part , easily discover mistake and correct it 图形编程软件从图形数据库中调取零件图后即可作为编制加工程序的依据,从零件设计到数控加工编程,数据信息流是连续的,所以有利于计算机辅助设计和制造的集成,并可形象地模拟刀具轨迹与被加工零件之间的关系,容易发现和修改错误,提高了可靠性。
