本科毕业设计（论文） 题 目 加热炉自动上料 薄壁气缸加工 摘要： 本文系统介绍了薄壁气缸作为典型薄壁零件的数控车削加工工艺。通过探讨薄壁气缸零件在数控车床加工中存在的易变形、零件尺寸精度、位置精度及表面粗糙度不易保证等技术问题，对加工难点进行分析，给出了加工工艺路线和加工方案，通过优化、完善夹具设计和切削参数，防止了薄壁零件加工变形、保证了较好的尺寸精度和位置精度，从而有效解决薄壁气缸作为薄壁气缸零件的车削加工难题。另一方面，该零件的数控加工采用宏程序不仅简化了数控程序的编写，而且可以运用于相同零件而不同规格的零件的加工。 关键词：薄壁零件 数控车床 夹具 工艺分析 Thin-wall Cylinder Liner Manufacturing Abstract：The paper systematically introduces the typical parts as thin thin air cylinder of nc machining process. Through the discussion in thin-walled cylinder parts CNC lathe machining in yi deformation, parts size accuracy, precision and surface roughness easy assurance for processing technical problems, difficulties are analyzed, and the processing route and processing scheme, through the optimization, perfect fixture design and cutting parameters, prevent the machining deformation of thin-walled and guarantee good precision and accuracy, thus effectively solve the position of thin-walled cylinder cylinder parts of a thin-walled difficult machining. On the other hand, this part of the nc processing using macro programs only simplifies the nc program, and can be used in the same parts and components of different specifications.
