TL;DR: In this article, the utility model of a roller burnishing tool for machining an excircle, an R surface and an end surface, which comprises a roller head and a tool shank, was presented.
Abstract: The utility model discloses a roller burnishing tool for machining an excircle, an R surface and an end surface, which comprises a roller head and a tool shank, wherein the roller head and the tool shank are arranged on a tool rest of a lathe The roller burnishing tool is characterized in that the head of the tool shank is an inclined tubular bearing block integrated with a shank body into a whole; the included angle alpha between the inclined tubular axial line and the axial line of the shank body is 45 degrees; a through hole is arranged at the lower part of the bearing block and is C-shaped; the opening direction of the C-shaped through hole and the direction of the roller head are positioned on the same side; a thrust bearing and a radial bearing are sequentially arranged on a shaft of a disk-shaped roller head; a gasket is arranged between bearings; and two ends of the bearings are fixed on the bearing block at the head part of the tool shank by two positioning covers The utility model has the beneficial effects that the roller burnishing tool integrates the functions of the excircle, the R surface and the end surface of a processing workpiece, has compact structure and is convenient to use Compared with a process of respectively using the traditional three hobbing cutters, the utility model saves labor force, physical materials and time which are contained in the processing procedure and remarkably reduces the processing cost of the workpieces

TL;DR: In this article, the nano-drone burnishing process was performed on the surface of Al7175-T74 specimens and the results showed that the minimum surface roughness and maximum microhardness values can be reached in nano and dry roller burnishing processes at the penetration depth of 0.4 mm.
Abstract: The burnishing process is one of the non-removal finishing processes, which is employed to enhance surface quality, corrosion property, and surface microhardness. In this study, the dry burnishing process was performed on the surface of Al7175-T74 specimens. Furthermore, nanofluid containing alumina/graphene nanocomposite was employed to perform the Nano burnishing process on the same specimens. The results show that the arithmetic surface roughness parameter in nanofluid burnished samples is decreased by approximately 0.277 μm, 0.233 μm, and 0.345 μm for the penetration depths of 0.2, 0.3, and 0.4mm comparing to those of dry burnishing process. Moreover, microhardness values in Nano and dry burnishing processes are directly related to the penetration depth parameter. The results reveal that the values of microhardness for the nanofluid burnished samples with four penetration depths of 0.2, 0.3, 0.4, and 0.5 mm are increased about 3, 28, 42, and 39 Vickers comparing to those values of dry burnishing process. The results prove that the minimum surface roughness and maximum microhardness values can be reached in Nano and dry roller burnishing processes at the penetration depth of 0.4 mm. Eventually, analyzing elements distribution on the surface of burnished aluminum alloy specimens confirm that the alumina/graphene nanocomposite embedded in the burnished surfaces during Nano burnishing process.

TL;DR: In this article, a review on performance improvement of roller burnishing process is presented and the process parameters mostly considered are burnishing speed, feed rate, number of passes and depth of penetration.
Abstract: This paper presents a review on performance improvement of roller burnishing process. Roller burnishing is a surface finishing process which is economical as compared to other surface finishing process. Roller burnishing along with good quality surface finish also gives improved surface properties. The process parameters mostly considered are burnishing speed, feed rate, number of passes and depth of penetration. Roller burnishing does not require any special arrangement for the process and can be easily carried out on a conventional lathe machine also.

TL;DR: In this article, a cylindrical burnishing roller was proposed for smoothening the access of a vane into a groove and performing surface burnishing for reducing damage efficiently and stably at low cost.
Abstract: PROBLEM TO BE SOLVED: To provide a roller burnishing tool capable of smoothening the access of a vane into a groove and of performing a surface burnishing for reducing damage efficiently and stably at low cost. SOLUTION: This roller burnishing tool includes a shank detachably mounted on the drive section of a machining device, a drive shaft inserted and held in a cylindrical hollow section in the shank, and a generally cylindrical burnishing roller rotatably supported at the end of the drive shaft with a holder interposed therebetween. The burnishing roller is so formed that the ride section having a thickness corresponding to the width of a groove is integrally formed at the cylindrical outer peripheral surface center over the entire circumference. Both side wall surfaces of the ridge section and the outer peripheral surface of the roller are continued with each other through a curved surface with an arcuate cross section in the diameter direction of the cylindrical shape.

TL;DR: In this paper, an experimental work was carried out on various Aluminium alloys, such as Al 2014 and Al 6063 using different burnishing parameters such as cutting speed, feed, no of passes and depth of cut using burnishing tool.
Abstract: Roller burnishing is one of the surface finishing processes without removing of a material, where a roller rolls over the machined surface under high pressure and flattens, the roughness peaks into valley. It will improve surface finish, as well as enforces favorable compressive residual stresses and raises hardness in functional surfaces. Aluminium alloys find attractive alternate for high strength applications. In this experimental work, burnishing operation is carried out on various Aluminium alloys, such as Al 2014 and Al 6063 using different burnishing parameters, such as cutting speed, feed, no of passes and depth of cut using burnishing tool. Through this experimental work, parameter that affects the surface roughness and surface hardness, on Al 2014 and 6063 material was identified and its influence on these responses was discussed. Also, the studies include the application one of the machine learning techniques is fuzzy logic, in the aspects of modeling and optimization of various process parameters applied, with roller burnishing process. This would give the comprehensive idea on choosing an optimum burnishing condition.
