动态工艺尺寸设计方法研究

Research on Planning Approach of Dynamic Technology Dimension

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．

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.
