Method Of Remote Cooperative Design And Its Application In Computer-Aided Fixture Design System

With the development of information science and technology, product design mode and productive conception in manufacturing enterprises are being changed. Development mode of manufacturing progress is influenced profoundly by networking technology. It makes the networking technology play more and more important role in running an enterprise in the mode of globalization and agility. According to distributed design features of mechanical product, studying and implementing a CAD technology of remote cooperative design which can rapidly adapt to requirement of enterprise are of great importance in theory and practice.This article first describe the methods of construct a frame for remote cooperative designing, and describes how to include the theory of parallel engineering in the process of designing and manufacturing. The article also analysis the situation of the pattern making in the manufacturing enterprises. And bring forward a model of Web-based fixture designing system, using the Microsoft Developing tools to develop new software. This software cans assistant the engineers of different places to coordinate and work together. We developed a program that can communicate between different users, and it can be used in the remote cooperative design.In the process of fixture designing, the calculating and collating of the forces in the fixture is very important. In order to assist the designers to take the advantage of the computer aided designing system; we use a math model to describe the calculating of the forces. And by an example of eccentric fixture, we illustrate how to develop the computer aided calculating and collating software.In order to optimize the resources in the manufacturing enterprise, we need to process the graphic data in the plotting devices. In this article, we describe how to put all the graphics in a layout that can save the plotting material. Using this software, the manufacturing enterprise can largely low down the cost of plotting.Usually there is much computer aided design software in an enterprise, and the format of this software is not compatible. When it conies to plot, this is inconvenience. The article describes a model of handling the obstacle, and by using the virtual device driver mode of Microsoft, we develop software that can plot different kinds of graphic files. This software can be used in various platforms and can plot and save the graph conveniently.
