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.
