摘 要 随着科学技术飞速发展和经济竞争的日趋激烈，机械产品的更新速度越来越快，数控加工技术作为先进生产力的代表，在机械及相关行业领域发挥着重要的作用，机械制造的竞争，其实质是数控技术的竞争。数控编程技术是数控技术重要的组成部分。从数控机床诞生之日起，数控编程技术就受到了广泛关注，成为CAD/CAM系统的重要组成部分。以数控编程中的加工工艺分析及设计为出发点，着力分析零件图，从数控加工的实际角度出发，以数控加工的实际生产为基础，以掌握数控加工工艺为目标，在了解数控加工铣削基础、数控铣床刀具的选用、数控加工工件的定位与装夹、拟定加工方案、确定加工路线和加工内容以及对一些特殊的工艺问题处理的基础上，控制数控编程过程中的误差，从而大大缩短了加工时间，提高了效率，降低了成本。 关键词：多边形凸台零件；铣削加工；工艺分析 Abstract With the rapid development of science and technology and increasingly fierce economic competition, mechanical products, updates faster and faster, CNC machining technology as a representative of the advanced productive forces, in the machinery and related industries play an important role in the field of mechanical manufacturing competition, and its?CNC technology is essentially the competition. CNC programming technology is an important part of numerical control technology.?From the date of the birth of CNC machine tools, CNC programming technology to be widespread attention, a CAD / CAM system is an important component.?To NC programming process analysis and design as the starting point and focus of part drawings, from CNC machining practical point of view, the CNC machining of the actual production as the basis to master the digital processing technology as the goal, the understanding of NC milling based on?CNC milling machine tool selection, CNC machining workpiece positioning and clamping, the development processing program to determine the processing route and the processing of content as well as some special deal with the problem on the basis of process control in the process of NC programming error, thus greatly reducing the processing?time and improve efficiency and reduce costs.? The main graduation Convex polygon machining technology, fixture design and automation programming for analysis.?In the design, through parts of the graphical analysis, material analysis, selecting the processing of rough size, in addition to the processing procedure, process analysis, which according to the process
