To integrate CAD and CAM systems, data for CAM system such as dimensional tolerance, geometric tolerance and surface roughness must be generated from CAD data. This sort of technical information is generally obtained in the course of detailing part specifications from assembly drawing. This study discusses a method of automatic determination of part specification for a rotational functional units of machines such as spindle head or gear box. The determination of technical information for machining is based on the assembly data model which consists of fit and contact relations among parts. The method of dimensional tolerancing along shaft axis proposed is formulated not to violate the clamping function which is realized by bolts and nuts. It is formulated as a set of rules which extracts the loops of connective relations and sets dimensional tolerance. The rule to set radial tolerance, geometric tolerance and surface roughness from connective relations and part function is also described. An experimental prolog program, which automatically generates tolerance information by using the rules mentioned above, proved itself to work properly through examples.
