数字翻译成中文 Digital manufacturing technology is the product of the combination of advanced manufacturing technology and information technology, as an important development direction of advanced manufacturing technology, advanced manufacturing technology at home and abroad has become a research hotspot, embodies the development trend of manufacturing technology and the discipline front.Digital factory is one of the key links in the digital manufacturing, digital technology the main factory solve the gap between product design and manufacturing, reduce the uncertainty of between design and manufacturing, production and manufacturing process in the digital space compression and advance, makes possible 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 gradually realize the simple use of Computer graphics can"t 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 product design. So the abbreviation of CAD by Computer Aided Drawing instead of Computer Aided Design, CAD is no longer just the computer-aided Drawing, but helped create, modify, analyze and optimize the Design of the technology.
2、CAE---计算机辅助工程分析
CAE (Computer Aided Engineering)通常指有限元分析和机构的运动学及动力学分析。
有限元分析可完成力学分析(线性.非线性.静态.动态)；场分析(热场、电场、磁场等)；频率响应和结构优化等。机构分析能完成机构内零部件的位移、速度、加速度和力的计算，机构的运动模拟及机构参数的优化。
CAE (Computer Aided Engineering) usually refers to the finite element analysis and institutional analysis of the kinematics and dynamics. Finite element analysis can be completed mechanics analysis (linear, nonlinear, static, dynamic); Field analysis, thermal field and electric field, magnetic field, etc.); Frequency response and structure optimization, etc. Mechanism analysis can be done in parts of the calculation of displacement, velocity, acceleration and force, mechanism motion simulation and parameter 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 of computer-aided manufacturing, can according to the CAD model of automatic generation of parts processing nc code, the dynamic simulation of machining process, at the same time to complete in the implementation process of interference and collision check. CAM system is combined with digital equipment can realize the paperless production, the realization of the CIMS (computer integrated manufacturing system) lay the foundation. CAM is the most core technology in numerical control technology. Structure parts usually adopt the space rectangular coordinate system of the digital quantity point, line and plane, said CAM is to use the numerical control machine tool motion according to the digital quantity control, complete parts processing.
4、CAPP---计算机辅助工艺规划
世界上最早研究CAPP的国家是挪威，始于1966年，并于1969年正式推出世界上第一个CAPP系统AutoPros，并于1973年正式推出商品化AutoPros系统。美国是60年代末开始研究CAPP的，并于1976年由CAM-I公司推出颇具影响力的CAP-I"s Automated Process Planning系统。
The first country to research of CAPP is Norway, began in 1966, and in 1969 officially launched the world"s first AutoPros CAPP system, and in 1973 officially launched commercialization AutoPros system. The United States is the end of the 60 s to research of CAPP, and in 1976 by a CAM - I launch of influential CAP - I "s Automated Process Planning system.
5、PDM---产品数据库管理
随着CAD技术的推广，原有技术管理系统难以满足要求。在采用计算机辅助设计以前，产品的设计、工艺和经营管理过程中涉及到的各类图纸、技术文档、工艺卡片、生产单、更改单、采购单、成本核算单和材料清单等均由人工编写、审批、归类、分发和存档，所有的资料均通过技术资料室进行统一管理。
自从采用计算机技术之后，上述与产品有关的信息都变成了电子信息。简单地采用计算机技术模拟原来人工管理资料的方法往往不能从根本上解决先进的设计制造手段与落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, 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 technology, the information related to the product into electronic information. 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 management. To solve this contradiction, PDM technology must be used.。
