Experimental Study of Vibratory Turning with Low Frequency of the Mechanical Vibration Device and on the Surface Texture
Abstract:
Based on the engine lathe, the vibratory turning experiment system was built up with low frequency of the mechanical vibratory device. Orthogonal experiment was carried out for the findings of the chip configuration, chip breakage, and the surface roughness with relationship of the cutting engagement especially the combination of the vibratory frequency, amplitude, and the feed and cutting velocity. Regressive analysis was done for the empirical formula of the roughness with parameters of vibratory turning engagement. From the experiment it has been shown that the higher the frequency is in vibratory turning, the smoother the machined surface is, other conditions being equal. The surface roughness increases with the feed, at the same frequency. The cutting tool was still smooth on the rake and flank and along the cutting edges all the time in vibratory turning. Because of the vibration and the lubrication the BUE can hardly be built up, being good for the surface integrity.
