Determination of Surface Roughness by Ball Burnishing Process Using Factorial Techniques
Burnishing is a method of finishing and hardening machined parts by plastic deformation of the surface. Experimental work based on central composite second order rotatable design has been carried out on a lathe machine to establish the effects of ball burnishing parameters on the surface roughness of brass material. Analysis of the results by the analysis of variance technique and the F-test sh...
متن کاملAnalysis of Surface Roughness and Micro-hardness in Roller Burnishing of Aluminum Alloy 6061
Burnishing is a chip-less finishing process, in which a hard roller or ball presses the surface layer of part to perform plastic deformation in the surface layer and produce improved finish, enhanced hardness and compressive residual stresses on the surface of special materials such as Aluminum and Brass. In the following research, the effect of input parameters such as feed rate, cutting speed...
متن کاملExperimental Investigation of the Influence of Burnishing Parameters on Surface Roughness and Hardness of Brass Alloy
Nanoparticles of iron oxide (Fe3O4) were obtained by Coprecipitation with synthesis time of 30, 60 and 90 min. The morphology of the samples was investigated by scanning electron microscopy (SEM) and structural characteristics were obtained by X-ray diffraction (XRD). The crystallite size was calculated from the spectrum X-ray diffraction with the application of the Scherrer equation and Winfit...
متن کاملUltrasonic reflection coefficient and surface roughness index of OA articular cartilage: relation to pathological assessment
BACKGROUND Early diagnosis of osteoarthritis (OA) is essential for preventing further cartilage destruction and decreasing severe complications. The aims of this study are to explore the relationship between OA pathological grades and quantitative acoustic parameters and to provide more objective criteria for ultrasonic microscopic evaluation of the OA cartilage. METHODS Articular cartilage s...
متن کاملSurface Roughness Prediction Modeling for AISI 4340 after Ball End Mill Operation using Artificial Intelligence
Now a days a manufacturing system is oriented towards higher production rate, quality, and reduced cost. Surface roughness is an index for determining the quality of machined products and is influenced by the cutting parameters. In die manufacturing industries Surface roughness of dies are considered as a vital quality characteristic. For the complex shapes of a die, three dimensional machining...
