1、数字化制造技术是先进制造技术与信息技术相结合的产物，作为先进制造技术的重要发展方向，已经成为国内外先进制造技术研究的热点，体现了制造技术的发展趋势和学科前沿。数字化工厂是数字化制造中关键环节之一，数字化工厂技术最主要解决产品设计和产品制造之间的鸿沟，降低设计到生产制造之间的不确定性，在数字空间中将生产制造过程压缩和提前，使生产制造过程在数字空间中得以检验，从而提高系统的成功率和可靠性，缩短从设计到生产的转化时间。Digital manufacturing technology is the product of the combination of advanced manufacturing

4、ble the testing of manufacturing process in the digital space, thus improve the success rate and reliability of the system, from design to production of transformation time.数字化制造技术的内容如下：1、CAD-计算机辅助设计CAD在早期是英文Computer Aided Drawing (计算机辅助绘图)的缩写，随着计算机软、硬件技术的发展，人们逐步的认识到单纯使用计算机绘图还不能称之为计算机辅助设计。真正的设计是整个产品
5、的设计，它包括产品的构思、功能设计、结构分析、加工制造等，二维工程图设计只是产品设计中的一小部分。于是CAD的缩写由Computer Aided Drawing改为 Computer Aided Design，CAD也不再仅仅是辅助绘图，而是协助创建、修改、分析和优化的设计技术。 CAD is in the early English Computer Aided Drawing (Computer Aided Drawing), with the development of Computer hardware and software technology, people graduall
6、y realize the simple use of Computer graphics cant call it Computer Aided design. The real design is the design of the product, it includes product design, functional design, structural analysis, processing and manufacturing, etc., 2 d engineering drawing design is only a small portion of the produc

10、ter optimization.3、CAM-计算机辅助制造CAM（Computer Aided Manufacture）是计算机辅助制造的缩写，能根据CAD模型自动生成零件加工的数控代码，对加工过程进行动态模拟、同时完成在实现加工时的干涉和碰撞检查。CAM系统和数字化装备结合可以实现无纸化生产，为CIMS（计算机集成制造系统）的实现奠定基础。CAM中最核心的技术是数控技术。通常零件结构采用空间直角坐标系中的点、线、面的数字量表示，CAM就是用数控机床按数字量控制刀具运动，完成零件加工。CAM (Computer Aided Manufacture) is the abbreviation o

16、后的资料管理之间的矛盾。要解决这个矛盾，必须采用PDM技术。With the promotion of CAD technology, the original technical management system is difficult to meet the requirements. Before using computer aided design, product design, technology and management involved in the process of all kinds of drawings and technical documents,
17、process CARDS, production order, change order, purchase order, cost accounting list and bill of materials are written by artificial, examination and approval, classification, distribution and the archive, all of the information by technical document for unified management. Since the computer technol

Simply computer technology are adopted to simulate the original artificial management information often cannot fundamentally solve the advanced design and manufacturing method and behind the contradiction between the data manag
19、ement. To solve this contradiction, PDM technology must be used. PDM（产品数据管理）是从管理CAD/CAM系统的高度上诞生的先进的计算机管理系统软件。它管理的是产品整个生命周期内的全部数据。工程技术人员根据市场需求设计的产品图纸和编写的工艺文档仅仅是产品数据中的一部分。PDM系统除了要管理上述数据外，还要对相关的市场需求、分析、设计与制造过程中的全部更改历程、用户使用说明及售后服务等数据进行统一有效的管理。PDM关注的是研发设计环节。 6、ERP-企业资源计划企业资源计划系统，是指建立在信息技术基础上，对企业的所有资源（物流、
