毕业设计(论文)-基于UG下的型腔零件数控仿形加工.doc

基于UG下的型腔零件数控仿形加工 摘 要： 数控加工需要输入加工程序，当零件过于复杂时，程序会很多，手动输入程序会很繁杂，而用UG进行仿形加工，再自动生成程序，可减少不必要的时间浪费，也可以了解加工过程中的易错之处，而UG就提供一个数控加工模拟与仿真的平台。UG具有实体造型、曲面造型、工程图的生成和拆模等功能。通过UG三维造型、仿形加工可以比手动绘图、手动编程来的简便、也可以提早发现问题、降低错误几率。本论文主要利用UG软件对型腔零件进行了三维造型，同时制定了加工工艺路线，并进行了仿形加工。 关键词： UG CAD/CAM? 车床加工 数控工艺 仿真加工 Abstract Need to enter the NC machining program, when the part is too complicated, the program will be a lot of manual input process will be very complicated, but with the Profiling of UG, then automatically generated procedures, reduce unnecessary waste of time, you can also understand the processplace in the error-prone, while the UG to provide a simulation of NC machining and simulation platform.UG has a solid modeling, surface modeling, engineering drawing generation and form removal and other functions.By UG dimensional modeling, profiling than manual drawing process can be manually programmed to the simple, early detection of problems can reduce the error probability.In this thesis, using UG software parts of a three-dimensional shape of the cavity, while establishing a processing line, and had Profiling.
