Abstract:	In machining processes such as drilling and milling, cutting force is a function of the material property of the workpiece, depth of cut, feedrate of the cutting tool and motor speed. In order to maintain the quality of the machining and extending tool life, cutting force variation must be suppressed as fast as possible. Traditional cutting force control requires torque transducer implemented in the working table or the spindle to measure the cutting force on the tool. This approach is not popular since the addition of torque transducer increases the cost of the system significantly. This paper proposed a cutting torque control scheme which dose not require direct torque measurement device for the machine tools using induction spindle motor drives. A fuzzy logic based observer suitable for ac induction motor was employed to estimate the cutting torque. Preliminary result have shown that the fuzzy observer was able to track the cutting force with high bandwidth.
