零件工艺图与设计图的尺寸校对技术研究

Research on Dimension Verification between Part Process Drawing and Design Drawing

讨论了工程零件设计图和工艺图尺寸校对的设计与实现。对其中各主要模块:加工面图素确定模块,尺寸单元分类模块,在原设计图上寻找和工序图中的尺寸标注单元相对应的尺寸标注单元模块,工序图和设计图中尺寸单元提取模块等模块的设计思路和算法都作了较为详细的讨论。解决了加工面图素的确定、尺寸标注单元的分类、确定尺寸单元约束图素、确定设计图与工艺图中的对应尺寸单元并加以比较等问题。并给出了各模块算法的程序流程图。

The paper mainly debate the development and design of the problem of dimension verified between part process drawings and design drawing.And the primary moudel:determination of process facies,dimension classified moudel,determination of dimension in part process drawings corresponding to dimension in design drawing,extracting dimension from process drawings and design drawing etc are debated.And all these problems:determination of process facies,dimension classification,determination of elements of dimension,determination of dimension in part process drawings corresponding to dimension in design drawing and comparation them have been solved.Flow charts of program are given.
