The skilled machinists carry out a very important role in the advanced manufacturing. Recently, the importance of the machining know-how (machinist's heuristic rules) has been recognized for the development in automatic working. Such heuristic rules gained through long experience may be regarded in a sense as fuzzy object. In this paper, a rational way for the acquisition of and model representation of the machinist's heuristic rules in turning operation is discussed. The main results of experiments are summarized as follows : (1) Using fuzzy logic, the machinist's heuristic rules for control to the dimensional error in diameter of cylindrical workpiece under machining were transformed into fuzzy control rules. (2) Fuzzy controller could be constructed with 16 heuristic rules, if-then rule structure and the learning system to correct fuzzy control rules. (3) In case of cutting test with the present fuzzy control system, every machining accuracy obtained was within the tolerance specified.
