设计简介
摘要:本世纪的科学技术正处于日新月异的变革之中,通过与计算机技术的紧密结合,人工智能技术、并行工程、面向装配、参数化特征建模以及关联设计等一系列与模具工业相关的技术发展之快、学科领域交叉之广前所未见,随着模具工业的快速发展,近几年来世界各国的软件开发商投入了巨大的人力和物力,针对各类模具的特点,将通用的CAD/CAM系统改造为模具行业专用的系统,取得了较大成效。
本设计是CAD/CAM技术在曲面加工中的应用。包括两大部分:一是摩托车塑料挡板模具的设计;二是模具型面的造型与数控仿真加工。在Mastercam 9.0环境下利用CAD功能进行摩托车塑料挡板模具的实体造型,利用CAM功能进行模具刀具路径的编制、模拟加工,并通过后处理生成数控加工程序。
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。并对注塑成型工艺及模具设计方面有了进一步的理解和提高。

Abstract: The science and technology has been changing in a fast pace. With the tight combination of computing technology, those technologies such as AI, Parallel project, face to assembling, The parameter turns the characteristic to set up the mold and associate designing which are relevant with modeling industry are growing incredibly fast. With the rapid growth of modeling industry, worldwide software companies invest huge capital and human resource to modify general CAD/CAM system into modeling industry specified system regarding the feature of all kinds of moulds.
This project is the use of CAD/CAM technology in the curved face process area. It includes two parts: First part is the design of the motorcycle plastics block’s injection mould. Second part is mould sculpt design and numerical emulation machining. We use Mastercam 9.0’s CAD function to design the he motorcycle plastics block’s injection mould and use the CAM function to program the cutter path, simulate the process and generate numerical modeling program.
I hope to enhance the acknowledgement of the importance of the use of CAD/CAM technologies in modeling industry and have a further understanding of injecting mold craft and model design during the course of this research.
