基于UG的塑料凹模的數(shù)控加工

摘 要

    隨著數(shù)控技術(shù)的發(fā)展，數(shù)控技術(shù)給傳統(tǒng)制造業(yè)帶來了革命性的變化，制造業(yè)成為工業(yè)化的象征，而且隨著數(shù)控技術(shù)的不斷發(fā)展和應(yīng)用領(lǐng)域的擴大，它對一些重要行業(yè)的發(fā)展起著越來越重要的作用。隨著科技的發(fā)展，數(shù)控技術(shù)也在不斷的發(fā)展更新，現(xiàn)在數(shù)控技術(shù)也稱計算機數(shù)控技術(shù)，加工軟件的更新快，CAD/CAM的應(yīng)用是一項實踐性很強的技術(shù)。如像UG , PRO/E ,  Master CAM ,CAXA制造工程師等。
  數(shù)控技術(shù)是技術(shù)性極強的工作，尤其在模具領(lǐng)域應(yīng)用最為廣泛，所以這要求從業(yè)人員具有很高的機械加工工藝知識，數(shù)控編程知識和數(shù)控操作技能。本文主要通過對復(fù)雜零件的數(shù)控工藝分析與加工，綜合所學(xué)的專業(yè)知識，全面考慮可能影響銑削的因素，設(shè)計其加工工藝和編輯程序，完成要求。

Abstract
With the development of numerical control technology, numerical control technology for the traditional manufacturing industry has brought the revolutionary change, manufacturing has become the symbol of industrialization,and with the development of technology and application domain expansion. It is important to some of the development of industry that plays a more and more important role. With the development of science and technology, numerical control technology is in the development of updates. Now, numerical control technology are called computer numerical control technology. The application of CAD/CAM is a practical technique, like UG, PRO/E, Master CAM, CAXA manufacturing engineers, etc.
Numerical control technology is highly technical work, especially in the mold domain. Practitioners requires high machining technology knowledge, CNC programming knowledge and skills.This text based on the analysis of nc craft and machining, comprehensive knowledge of professional knowledge, comprehensive consideration the influence factors of milling process, design the craft and editing program, complete requirements.

Keywords: milling, CAD/CAM, UG, nc machining
