3D analysis of surface topography in vibratory turning.

High quality of machined surfaces is an important requirement in production industries. Therefore, different methods such as ultrasonic vibrations are implemented to improve this parameter. In this study, it is tried to specify some of effective parameters on surface improvement in ultrasonicassisted turning. Accordingly, a series of experiments in the way of conventional and vibratory turning are conducted where surface roughness and surface topography are evaluated as main objectives of this work. Furthermore, analysis of tool wear and radial displacement of tool and workpiece are carried out for explanation of surface enhancement in vibratory turning. As a result, it is shown that generated typical peaks and valleys in conventional turning are flattened and reduced in vibratory turning which is explained by existence of lower radial force.
