Abstract : technology dimensions of work parts always exceed the determined technology dimension limits . but when the work parts are big enough , it is still possible and valuable to modify the work parts " following technology process and technology dimensions , which are respectively called as dynamic technology process ( dtp ) and dynamic technology dimension ( dtd ) , to ensure them to be qualified . a mathematical model is proposed which is about how to plan the dtd once the dtp is determined . a software has been written to testify the correctness of the above model . this model will be very useful in the capp and online quality assurance in the manufacturing of precise machine parts 文摘:工件的工艺尺寸在工艺过程中经常会超出许可的范围,但当这些超差工件仍有足够的加工余量时,通过修改其后续工艺路线(称为动态工艺路线)及工艺尺寸(称为动态工艺尺寸)仍有可能将其加工成成品.本文提出了一种在后续工艺路线确定后如何确定后续工艺尺寸的数学模型,并利用该模型成功地编制出了动态工艺尺寸设计的软件,且用很多事例验证了该模型的正确性.该方法可以应用于精密机械零件制造时的计算机辅助工艺过程设计及在线质量保证
Abstract : since nearly all of the dimension parameters in technological process planning are coupled together , manual method in the process dimension parameter planning ( pdpp ) is not always efficient and effective . in order to increase design efficiency and effect , an essential mathematic model about pdpp is established , and two basic constraint sets are given . this model is not only helpful to realize the automation and optimization of pdpp , but also useful to verify the correctness of existing pdpp methods and to find better pdpp methods 文摘:由于工艺过程设计所涉及到的所有尺寸参数几乎都是耦合着的,因此采用人工的、凭借经验的方法进行工序尺寸参数设计常常效率甚低.为了提高设计效率及经济效果,建立了一种工序尺寸参数设计的基本数学模型,并给出了两个基本可行域的结构.该模型的建立不仅可用于实现工序尺寸参数设计的最优化和自动化,而且可用于证明已有方法的正确性及发现更好的设计方法
