摘要
现代的CAD/CAM都是建立在数控技术之上的。掌握现代数控加工技术知识是现代机械专业里面必不可少的。在数控加工过程中，从零件的设计图纸到零件成品的合格。不仅要考虑到数控程序的编制，还要考虑到零件加工工艺路线的安排、加工机床型号的选择、切削刀具的选择、零件加工的定位装夹等一系列因素的影响。在开始编程前，必须要对零件设计图纸和技术要求进行详细的数控加工工艺分析。来最终确定哪些是零件的技术关键，哪些是数控加工的难点，以及程序的编制难易程度。
本次设计内容为车削轴类零件数控加工工艺及编程加工。具体介绍了数控车床加工的特点、加工工艺分析以及数控编程加工过程，以及夹具的确定等等。
关键词：数控车床；数控编程；数控加工工艺
Abstract
Modern CAD/CAM is based on numerical control technology. Mastering the knowledge of modern NC machining technology is essential in modern mechanical engineering. In the process of NC machining, From the design drawing of the part to the qualification of the finished product of the part. Not only the preparation of the NC program, but also the arrangement of the machining process route of the part, the selection of the type of the machine tool, the choice of the cutting tool, The influence of a series of factors, such as positioning, clamping, etc. Before the beginning of programming, it is necessary to carry out detailed NC machining process analysis on the part design drawings and technical requirements. Finally, it is necessary to determinewhich parts are the technical key andwhich are the number The difficulty of controlling processing and the difficulty of programming.
The content of this design is NC machining technology and programming machining of turning shaft parts. The characteristics of NC lathe machining, machining process analysis, NC programming machining process and fixture determination are introduced in detail.
Keywords: NC lathe; NC programming; NC machining technology
