The Potential of Computerized Interactive Training in Manufacturing

Abstract

Advances in manufacturing technology has fundamentally changed the skill and knowledge requirements of machine operators. Our paper explores the potential training applications of computer-based multimedia or hypermedia environments in advanced manufacturing. We developed a prototype interactive training program for electrodischarge machining (EDM). The EDM Trainer relies heavily on graphic imagery and is based on a graphical direct manipulation design model. Ten highly skilled machinists/tool makers were recruited to evaluate the program. Participants received conceptual questions before and after training. We tracked user interactions with the program and finally, we had them answer a questionnaire. The results indicated that the trainer was effective in helping operators gain explicit conceptual knowledge. Operators were able to use the trainer right away and they took advantage of a variety of navigation links to freely explore the program.
