Abstract

This paper describes the development process and requirements of a multimedia engineering tutor as well as the specific development of a multimedia injection molding tutor at the University of Massachusetts Amherst. The injection molding tutor is beneficial to any user that has little or no previous knowledge of injection molding and design for injection molding.

I. Introduction

There has been a growing drive to incorporate more manufacturing into the engineering curriculums across the United States. With this drive there has been a need for developing better teaching tools to aid in teaching the vast spectrum of manufacturing processes in as efficient a manner as possible. Due to the fact that many engineering concepts are difficult to understand, tools that go beyond simple classroom lecture and textbook work are starting to be developed.

Incorporating design for manufacturing (DFM) methodologies into the undergraduate curriculum at the University of Massachusetts (UMASS) Amherst has been one of the attempts used to introduce students to both product design as well as product manufacturing. At UMASS Amherst an interactive multimedia tutor specifically for teaching design for injection molding has been developed. The purpose of the Injection Molding Tutor (IMT) is to assist the user, a student or anyone not familiar with the manufacturing process of injection molding, in understanding the relationship between part design and the ease or difficulty of producing the part.

The injection molding tutor is divided into two distinct modules, an Introduction Module and an Experiential Module. In the former module the user is introduced to the injection molding process via a series of screens that contain both text and animations. The emphasis in the introductory module is to make the user aware of the relationship between part geometry and the ease or difficulty of constructing the dies (tooling) required to produce the part. The second module provides the user with the opportunity to determine how well they have learned/absorbed the concepts presented in the first module. In this module the user is allowed to design and 'build' a part from a rather restricted family of part geometries. If the user has understood the concepts presented in the first module, they should be able to design easy to mold parts and/or understand why the parts they have designed are difficult to mold. In the second module the user is able to obtain advice concerning their proposed design and to obtain an animated illustration of the
