Abstract

This paper presents the effect of different tool nose radii of 0.03, 0.1, 0.2 and 0.4 mm on tool wear, surface roughness, chip morphology, signals acquired from different sensor such as Acoustic Emission (AE), accelerometer and cutting force dynamometer in micro turning of stainless steel (SS 316L). Experiments have been carried out with coated tungsten carbide insert up to 60 minutes. Measurements and the signals are analysed for every 1st minute and 10th minute. It is observed that tool wear and chip width is found to be increasing, while Ra is found to be following non-uniform trend with increase in the nose radius. From the AE and vibration signal analysis, it is found that the dominant frequency of the signals increases with increase in the nose radius. Among the cutting forces, the tangential force (Fy) is found to be more sensitive to the tool wear status compared to that of the thrust force (Fx) and feed force (Fz). This study will be useful for the manufacturers to monitor the condition of the tool online while micro turning of SS 316L.
