This paper describes a knowledge based system developed for specification of ISO fits for the manufacture of rotational mating components with interference, clearance and transition fit types. Either shaft basis or hole basis system can be used for specification of tolerances. The knowledge base consists of various tolerance information, fit types, rules and procedures. The rulebase design is based on ISO recommendations for standard fits and tolerances. Given basic information such as diameter, type of fit and achievable deviation, the rule oriented system for computer aided tolerancing (ROSCAT) provides the ISO fit that is best suited for the given manufacturing conditions.
