Metal-Cutting Operations

Roller burnishing is a surface finishing operation in which hard, smooth rollers, or balls are pressed against the work surface to generate the finished surface through plastic deformation [66–68]. Roller burnishing is used in combination with or as a replacement for lapping, honing, microsizing, grinding, or in some cases turning, milling, reaming, and boring. Burnishing is used to improve surface finish, control tolerance, increase surface hardness, and improve fatigue life.

The multi-roller burnishing technology is an efficient finishing operation to boost the surface integrity and production rate, as compared to the single ball and/or roller one. Nguyen and Le stated that the improvements in the SR and surface hardness (SH) were 96.0% and 45.0%, respectively for the burnishing carbon steel.[20] High-accurate Kriging models of the SH and roughness properties were proposed.[21] The optimal outcomes of the burnishing speed (BS), burnishing feed (BF), depth of penetration (DOP), and the number of rollers (N) were obtained to reduce the energy consumed (CE)[22] and noise emission.[23] Nguyen et al. indicated that the CE and power factor (FP) could be improved by 49.5% and 13.8%, respectively.[24] Similarly, Nguyen et al. presented that the CE and SR were reduced by 39.5% and 7.8%, respectively for the flood burnishing operation.[25]

Roller burnishing is a cold working metal method using hardened steel rolls for the surface integrity enhancement. This process is an efficient chip less surface, compared to other treatment techniques such as, grinding, polishing, lapping, and honing. Plastic deformation on the workpiece surface will occur as the peaks flow into the valleys under the burnishing pressure. Since this process can bring various attractive advantages, including low surface roughness, improved hardness, favorable residual stresses and high corrosion as well as fatigue resistance. The pre-machining, such as turning or milling process is necessary in order to ensure the technical requirements. Consequently, this roller burnishing is widely applied for finishing operations in terms of elastic-plastic or ductile materials.

The main scientific contribution of this paper is to expand the existing knowledge about the roller burnishing processes and its application in Inconel 718 alloys so used in the aeronautical industry in the development of engines among other applications. The roller burnishing, as a process, can eliminate machining steps such as grinding (reducing manufacturing costs), as it can correct errors in roundness deviations, increase the useful life of the manufactured piece (with gain in mechanical resistance), factors extremely valued by the aerospace industry, among others.
