传统制造系统的缺点

In conventional manufacturing, there is lots of time and money wasted on building the physical prototypes of the manufacturing processes to be used before the actual production starts. This takes a lot of time which can be used to optimize the product design and market the product in a better way. There is also lots of money and material wastage if more physical prototypes are required. With increasing competition in today’s world, the conventional way of setting up production processes causes the company a fortune. It was time for an innovation and this is how Virtual Manufacturing was born.

What is Virtual Reality?

Virtual Reality (VR) is an exciting new technology for which the most important benefits are the ability to do human-in-the-loop, real time, “what if” scenarios, reducing development time and reducing time to deliver products to the market. Virtual reality promises a ready ability to interact in three dimensional space. In particular it is possible to provide a visual simulation of familiar real-world environments, and to make changes within such an environment.

什么是虚拟制造？

Perhaps one of the most interesting and important of these recent developments is called “Virtual Manufacturing”. Often termed “The Next Revolution in Global Manufacturing”, virtual manufacturing involves the simulation of a product and the processes involved in fabrication. Virtual Manufacturing (VM) is defined to be an integrated, synthetic manufacturing environment exercised to enhance all levels of decision and control. In simple words, the vision of Virtual Manufacturing is to provide a capability to “Manufacture in the Computer”. Virtual Manufacturing (VM) is defined to be an integrated, synthetic manufacturing environment exercised to enhance all levels of decision and control.

实质上，VM最终将提供建模和仿真环境，如此强大的是，可以在计算机中模拟任何产品的制造/组装，包括相关的制造过程。这种强大的能力将考虑到生产环境中的所有变量从车间流程进程到企业交易。换句话说，VM将适应互动生产过程，流程规划，调度，装配规划，物流从进入企业的物流，以及相关的影响过程，如会计，采购和管理。此外，VM还降低了工具的成本，消除了对多种物理原型的需求，并减少了材料浪费。这使每个人都能“第一次搞定”。

VM利用非线性有限元分析技术提供有关产品的详细信息，这些信息仅用于优化可制造性，最终形状，残余应力和生命周期估计等因素。在VM的核心呈非线性FEA技术。

在制造的虚拟制造过程中包括以下步骤：

1. Preliminary Design Of Products.

2. Preparing product models ,assembly using 3d design Software like Solidworks, CATIA, Creo

3.Engineering And functional analysis

4. Manufacturing analysis

5.验证设计参数

6. Acceptable Design.

ADVANTAGES

FEWER PROTOTYPES –

您可以在虚拟环境中模拟的试验越多，您需要更完善您的设计所需的物理原型。这意味着您在工程和设计方面花费更多时间，较少的资源运行实际试验。虚拟原型设计比建立物理模型便宜，并通过试验和错误优化您的设计。它不完全替换物理测试，但它可以最大限度地减少努力并使产生的物理测试更加成功。

LESS MATERIAL WASTE –

If you build fewer physical models, you waste less material in the form of prototypes as well as the tooling used to create them.

降低工具成本 -

Again it follows that if you build fewer prototypes, then you develop fewer tools, which are typically very expensive. Furthermore, by modeling the tools, you can reduce tool wear, thus increasing tool life.

CONFIDENCE IN MANUFACTURING PROCESS –

Even if the tools are properly designed, the control of the tools may affect the quality of the part produced. VM allows you to simulate the part, the tools, and their control. This simulation can let you optimize your tool control before building prototypes, again letting you “get it right the first time”.

提高质量–

It improves their part quality by utilizing VM techniques.

There are numerous examples throughout this paper, and almost all of them result in a part with quality produced at lower cost than previously attained through traditional prototyping techniques.
