Abstract-Turning is one of the most popular convectional machining processes to remove the extra material from the rotating surfaces. In this process, a wedge shaped cutting tool penetrated toward the workpiece and removed the extra material in the form of chips. Almost all known materials can be machined by this process in different forms like external turning, internal turning, plain/cylindrical turning, step turning, taper turning, face turning etc. with selection of appropriate cutting tool for particular material. The aim of the present study is to summarize a report on the turning process including present and past research works. This paper present a brief overview on turning operation considering the different aspects and focus the future scopes of works in the same area, which is beneficial for the researches who work in the same field.

“…Wang et al 9 presented a theoretical and experimental investigation into the effect of the workpiece material on surface roughness in the ultraprecision milling process and proposed a new method to characterize material-induced surface roughness on the raster-milled surface. Chan et al 10 found that the surface roughness of the cutting surface was affected by both the process factors and material factors. Kong et al 11 investigated the effect of different factors on surface generation in ultra-precision raster milling and found that machining parameters, tool geometry, cutting strategy, and tool wear were the critical factors for achieving super mirror finish surfaces.…”

In ultra-precision fly-cutting machining, the aerostatic spindle is the key component, which has significant influence on the machined surface quality. The unbalanced spindle directly affects the machining accuracy. In this article, a prediction model of machining surface topography is proposed which involves the effect of the gas film performance of spindle in microscale. With the Weierstrass function, unstable transient response of the aerostatic spindle system is derived by the motion model of the spindle, which response signal represents the surface profile in the ultra-precision machining. Meanwhile, the experiment is performed with different rotation speed of the spindle. And the effect of the unbalanced aerostatic spindle on the surface generation is discussed in time and frequency domain. The conclusion shows that the similar cyclical surface ripple of the workpiece is independent of the spindle speed, and the rotation speed of the spindle and unbalanced spindle directly affects the machining surface topography. This study is quite meaningful for deeply understanding the influence rule of spindle unbalanced error from the viewpoint of machined surface and vibration frequency.

Abstract. The machined surface topography greatly influences the mechanical performance of workpiece. There exist many defects such as pits and scratches on machined surface in ultra-precision cutting of SiCp/Al composites. The existence of defects leads to the distortion of reference surface. It is necessary to investigate the filtering method of the machined surface in ultra-precision cutting of SiCp/Al composites. Firstly the machined surface of SiCp/Al composites is measured by confocal microscope. Then the Gaussian filtering method and robust Gaussian filtering method are used to construct the reference surface. The result shows that the robust Gaussian method is better for achieving the appropriate roughness data.
