  • 1404 The making of a teaching material to instinctively understand the tolerance of fits

抄録

To make a product, it must be mechanically designed and the parts must be machined and fitted. At this time, considering the size tolerance and geometric tolerance is important. Furthermore, the accurate knowledge of the size tolerance and geometric tolerance are one of the most important things required in mechanical designing, even after being employed. Content regards to size tolerance and geometric tolerance are included in the lessons of technical drawings for mechanical engineering and in mechanical designing and drawing. However, these lessons are lectures and many students find it difficult to understand the content of tolerance of fits just by listening to lectures. Therefore, a teaching material was made which made the tolerance of fits easy and instinctive to understand for the students. Through the questionnaire after the class, I realized that the students found the teaching material made it easy and instinctive for them to understand the tolerance of fits.
