CAI for Machine Design - Design of Hand Winches
Satoshi EMA, Hiroaki ODAKA

To acquire basic knowledge related to design methods, design procedures and drawing exercises have been done related to machine design and drafting. However, there are many problems which require improvement related to conventional practices. Using hand winches as the subject matter, CAI software for machine design was developed which would allow for such things as: the reduction of design time, confirmation of student designs, repeating designs, appropriate guidance for each drafting project, and designing multiple projects. Furthermore, this CAI was tested using 27 subjects. As a result, it was confirmed that this CAI was useful.
