Analysis on the Combination of Mechanical Design and Manufacturing and Computer Aided Technology

The timing scroll is an important feeding mechanism on packaging lines. As packaging line speeds have increased and the shape of containers has become more diverse, the techniques used for the design and manufacture of such timing scrolls have become critical for successful packaging line performance. Since 1980, various techniques have evolved to improve scroll design, manufacture and the associated line performance. In recent years, as CAD (computer aided design), CAM (computer aided manufacture) and CNC (computer numerical control) techniques have evolved, scroll design and manufacturing techniques began to be linked with computer techniques. In this paper, a scroll design and manufacturing package is presented which can be run on a minicomputer, such as a μ-VAX on an IBM PC clone. This scroll package can produce a timing scroll for any type of container with a correct pocket shape and good dynamic characteristic. Tests using carefully chosen containers have been made using this package and the results indicate that the scrolls obtained by this package have the correct pocket shape and good line performance. However, the design of a good pick-up geometry for some container shapes remains a problem.

Collaborative Activities

Abstract With the increasing globalization and expansion of the people’s activities, distance learning is getting wide attention. Distance learning is not a computer aided education system alone. What is important is that collaboration over the network is a prerequisite for that, so that the technology developed there will be easily utilized for distance manufacturing and other collaborative activities over the network. When we come to think of integrating design and manufacturing over the network, the problem of skill comes up. Skill plays a very important role in manufacturing. But most of the systems developed so far have been focusing their chief attention toward how rigously they can represent design and manufacturing knowledge and experience in terms of symbols, and non-symbolic approaches are still few. It is believed that motion occupies a large portion of skills, but the present systems being such, and in additon, such media as TV, video, etc are one way from a teacher to a student so that it is still very difficult to learn skills over the network, since skill learning requires much interactive processes. Otherwise, students find it very difficult what part of the model motion they should concentrate their focuses. If a teacher can edit the motion of a student and a student can watch how his or her motion is edited, the student will understand more easily what is wrong with his or her motion., and can identify where his or her attention should be focused. Based on this idea, we have developed a preliminary system for distance learning of skills to demonstrate the effectiveness of the approach.
