surface roughness of engineering parts is very significant property that effectively influences on the wear and fatigue strength. there are many methods for improving surface quality of engineering parts such as grinding, lapping and honing. one of the methods for improving surface quality is roller burnishing. roller burnishing improves surface quality of engineering parts by means of cold wor...

Burnishing is cold working process where hard roller are being pressed against irregular surface, so that surface finish and the micro hardness increases. In this study internal roller burnishing tool is used to burnish the drilled hole. Speed, feed, and number of passes have been varied using taguchi method to examine the surface finish and microhardness. Anova analysis is carried out. Surface...

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...

Energy and resource efficient systems often demand the use of light-weight materials with a specific combination of properties. However, these requirements usually cannot be achieved with homogeneous materials. Consequently, composites enabling tailored properties gain more and more importance. A special kind of these materials is aluminium matrix composites (AMCs), which offer elevated strengt...

Denomination Magnetism Aided Machining (MAM) comprises a number of relatively new industrial machining (firstly finishing and surface improving) processes being developed at the present time too. MAM is effective – among others – in polishing, deburring and burnishing of metal parts. The authors give a brief outline of these modern processes, and make an attempt to systematize them. The paper s...

Using thermal spraying various surface coatings consisting of different material compositions can be manufactured. Besides different solid phases the resulting coating microstructure often contains a non-negligible amount of pores. In this context a roller burnishing process with a hydrostatic ball-point-tool is examined to compact the thermally sprayed coating, thereby reducing porosity. The r...
