摘要:曲面类零件在制造业中处处可见,尤其是模具制造业。传统的设计制造方法是工程图、模线、样板、标准样件等工作方式,生产准备的周期长,制造精度低,生产效率也是低下。随着计算机技术在模具制造业中应用的不断发展,数控加工能力得到了大大提高,模具的设计与制造技术达到了空前的发展。模具CAD/CAM技术已成为模具行业革命化的标志。适应CAD/CAM技术的发展,改变传统的设计与制造方法是模具制造业的发展的方向.
本设计是CAD/CAM技术在锻模曲面加工中的应用。包括两大部分:一是摩托车护片模具的设计;二是模具型面的造型与数控仿真加工。在Mastercam 8.0环境下利用CAD功能进行摩托车护片模具的实体造型,利用CAM功能进行模具刀具路径的编制、模拟加工,并通过后处理生成NC程序。期望通过此课题的研究,能够提高自己对CAD/CAM技术在模具制造业中应用的重要性的认识。

Application of the CAD/CAM technology in Motorcycle Jacket’s Forging Mould Designing
Abstract: It is well known that surface parts can be seen everywhere in the manufacturing , especially in the mould manufacturing . The traditional design and manufacturing processes are the engineering drafting , lofting , template making , standard samples , etc. , which have the shortages of long production preparation period , low processing accuracy and production efficiency . With the developing of the computer technique’ application in the mould manufacturing , NC machining capability has been enhanced greatly ,and, the design and manufacturing technique of the mould has obtained enormous progress at the same time . The CAD/CAM technique has become the revolutionary sign in the mould industry . To be suitable for the tendency of CAD/CAM technique’ development and meet the requirement to change the traditional design /manufacturing modes are the developing direction of the mould industry .
This project is about the application of the CAD/CAM technique in the wrought mould surface processing . It contains two parts : one is about the mould design of the motorcycle jacket and the other is about the numerical control simulate process of the mould surface . Under the environment of Mastercam 8.0 , I will sculpt the mould of the motorcycle jacket using the CAD function , and then , I will weave the tool route , simulate processing and create the NC programme via the back disposing using the CAM function . And at last , I hope I can improve my cognition to the significance of the CAD/CAM technique’ application in the mould industry by the study of the task .

此次设计是Mastercam软件在摩托车护片型面加工中的应用,它包括两部分内容,即:一是摩托车护片模具的设计,二是摩托车护片模具型面的仿真加工。这是CAD/CAM技术在锻模生产中的应用实例。摩托车护片是摩托车前部用于穿接电缆的零件,起保护作用,它的作用决定了它的结构特征,通孔多槽,相应的模具设计虽然简单,但是比较精湛。摩托车护片型面的加工,因为Mastercam软件的应用,大大的提高了模具精确度和生产效率,缩短了生产周期,淋漓尽致地发挥了CAD/CAM技术在模具生产中的作用。
