FIAC-System (Fuzzy Intelligent & Automatic Control System) is developed in order to achieve the intelligent automation of grinding process. In this paper, fuzzy in-process control grinding techniques are adapted to wheel head infeed control, in which grinding phenomena are sensed and best grinding conditions are choiced by predictive fuzzy theory in real time. Main conclusions are as follows : (1) In FIAC grinding, the ideal infeed control grinding process, in which the bigger infeed rate should be given in early stage for high efficiency and gradually decreasing infeed rate to spark-out point should be given for high quality, can be established. (2) By means of estimating the size error on account of workpiece thermal contraction occurred after spark-out, final size error and the deflection become extremely smaller. (3) In size accuracy and surface roughness, FIAC grinding is superior to two plunge speed grinding which has same efficiency as FIAC one.
