The objective of the research was to analyse impact ultrasonic vibration assistance on wear resistance and topology enhancement AISI 1045 cylindrical steel samples after a ball burnishing process. Burnishing process parameters such as force, number passes assistance, or not, 40kHz wave. A screening design 3 factors with 2 central points planned. An improvement in when is applied, expected due e...
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...
Deep cold rolling (DCR) and low plasticity burnishing (LPB) process are cold working processes, which easily produce a smooth and work-hardened surface by plastic deformation of surface irregularities. The present study focuses on the surface roughness and surface hardness aspects of AISI 4140 work material, using fractional factorial design of experiments. The assessment of the surface integri...
Friction stir burnishing (FSB) is a surface-enhancement method used after machining, without the need for an additional device. The FSB process is applied on a machine that uses rotation tools (e.g., machining center or multi-tasking machine). Therefore, the FSB process can be applied immediately after the cutting process using the same machine tool. Here, we apply the FSB to the shaft material...
Abstract Diamond burnishing is a widely used finishing machining that can have positive effect on both the roughness of cut surfaces and its stress state. This paper focused examination theoretical real machined by sliding burnishing. In determining roughness, surface structure created pre-burnishing cutting (turning) was also considered. Two different modelling methods were to obtain data: CAD...
Burnishing, the plastic deformation of workpiece surface due to sliding contact with a tool called burnisher, is finishing operation widely used in various industries. In this work, impacts initial roughness Ra being burnished, nature friction zone, and clamping force on stability energy efficiency burnishing have been investigated. Experiments conducted without lubricant, represented by low-vi...
A hybrid metal-additive manufacturing (AM) process that combines laser-based powder bed fusion (PBF-LB) with interlayer burnishing is investigated using a comprehensive modeling framework to provide new insights into how the inhomogeneous microstructure and residual stress from laser affect induced field evolves during burnishing. Researchers have recently studied changes in resulting similar p...
The aim of this study was to determine the impact additions tungsten carbide and silicon microparticles lubricant used in burnishing process on tribological properties friction pairs. cylinders made AISI 1045 steel constituted a workpiece. Burnishing with SN150 base oil addition microparticles. tested materials were burnished forces 1000 N 1500 N. Before after process, surface roughness hardnes...
