Computer-aided selection of ISO manufacturing limits for interference fit joints

Consideration is given to the problem of selecting ISO manufacturing limits to be assigned to parts thats are to be connected via an interference fit joint. Factors such as the functional requirements of the end assembly, the manufacturing capabilities of the manufacturer concerned and the limitations imposed by this very nature of the ISO Limits and Fits system have been considered.An interactive computer program for the selection of ISO interference fits with nominal joint diameter less than 500 mm, written in MBASIC computer language, was developed. The program can run on a desk-top micro-computer and it is believed that its usage in industry will considerably facilitate the interference fit selection procedure.
