Special Issue Information

Dear Colleagues,

This Special Issue on “Advanced Surface Finishing Processes” aims to comprehensively collect and share knowledge on the manufacturing process used for surface finishing a component. Surface finishing is an essential post-processing step in any manufacturing cycle. Most metal, polymer, ceramic, and fiber components require stringent surface integrity (roughness, dimensional, tribological, and metallurgical properties) for effective and efficient performance. Both external and internal surfaces demand high-precision surface finishing. Aerospace, automobile, semiconductor wafers, photonics, and biomedical components require high-precision mirror polishing. The poor external surface finish affects the fatigue life, surface wear, and dimensional tolerance of a component. High-surface roughness on internal surfaces affects the fluid flow dynamics and wettability characteristics. Fluid contamination in fuel injection systems, exhaust manifolds, and medical drug delivery components results in catastrophic failures.

Burgeoning developments in additive manufacturing (AM) technology have re-emphasized the attention and need to develop advanced post-process surface finishing techniques. The poor surface quality of as-built AM components demands special processes for uniform surface finishing of complex geometries. The understanding of surface finishing on such highly intricate geometries is of high interest. The current issue aims to publish original research from a broad range of topics, not limited to surface finishing approaches. This includes new and advanced processes, including readily available industrial solutions that enhance the surface quality of a mechanical component.

The scope of the journal covers but is not limited to the following areas:

  • New process development;
  • Advanced surface finishing techniques;
  • Post-processing for additive manufacturing;
  • Surface and sub-surface enhancement;
  • Industry 4.0 and data-driven surface finishing;
  • Surface finish measurement techniques;
  • Non-destructive evaluation of surface roughness;
  • Surface finishing, challenges, and applications;
  • Robotic surface enhancement;
  • Coatings and surface treatments;
  • Advancements in conventional surface finishing processes;
  • Surface finishing and its effects on mechanical components.

In order to further study the Magnetic Abrasive Finishing with Electrolytic (EMAF) Process, we attempted to use rectangular wave pulse voltage for EMAF processing of SUS304 stainless steel, and the finishing characteristics were analyzed based on the experimental results in this paper. The EMAF process has been studied for years, but the study of Magnetic Abrasive Finishing with the. Pulse Electrolytic (P-EMAF) process has not been published. Therefore, in this study, the finishing characteristics of the P-EMAF process corresponding to different frequencies (1 Hz, 10 Hz, 100 Hz, 1 kHz) and duty ratios (25%, 50%, 75%) are explored. The evaluation of the P-EMAF processing includes the surface roughness (SR) and the amount of material removal (MR); the surface of the workpiece was also observed by an optical microscope before and after processing. After analyzing the experimental results of P-EMAF processing, a set of comparative experiments between P-EMAF processing and MAF processing was carried out. In this study, when the Urms 6 V pulse voltage of rectangular wave with 1 Hz and duty ratio 50% was used, a better processing result could be obtained. The processing efficiency of the P-EMAF process was also higher than that of the MAF process under the same experimental conditions. Full article

Abrasive flow machining (AFM) is considered as one of the best-suited techniques for surface finishing of laser powder bed fused (LPBF) parts. In order to determine the AFM-related allowances to be applied during the design of LPBF parts, a numerical tool allowing to predict the material removal and the surface roughness of these parts as a function of the AFM conditions is developed. This numerical tool is based on the use of a simplified viscoelastic non-Newtonian medium flow model and calibrated using specially designed artifacts containing four planar surfaces with different surface roughnesses to account for the build orientation dependence of the surface finish of LPBF parts. The model calibration allows the determination of the abrasive medium-polished part slip coefficient, the fluid relaxation time and the abrading (Preston) coefficient, as well as of the surface roughness evolution as a function of the material removal. For model validation, LPBF parts printed from the same material as the calibration artifacts, but having a relatively complex tubular geometry, were polished using the same abrasive medium. The average discrepancy between the calculated and experimental material removal and surface roughness values did not exceed 25%, which is deemed acceptable for real-case applications. A practical application of the numerical tool developed was demonstrated using the predicted AFM allowances for the generation of a compensated computer-aided design (CAD) model of the part to be printed.

Technological progress in hybrid bearings developed high wear and abrasion resistant materials for rolling elements. The manufacturing process of bearing balls presents new challenges, as nowadays, it requires time-consuming and costly processes. In this frame, the bearing manufacturing industry is demanding improvements in materials, geometry, and processes. This work aims to investigate new abrasive coatings for grinding wheels for Si3N4 ball manufacturing. Tribological pin on disk tests are performed on samples of grinding materials (disk) versus a Si3N4 ball (pin). Two samples of specimens coated with an electrodeposited diamond and diamond-reinforced metal matrix composite are examined to measure the abrasion rate and the wear resistance of Silicon Nitride Si3N4 balls, considering the influence of sliding speed and the effect of coating deposition on diamond particle density and granulometry. The measurements estimated the specific wear coefficient k, the height wear surface h, and the wear rate u of the Si3N4 balls. The results pointed out that by increasing the sliding speed, the abraded volume increases for both the coatings. The parameters affecting the abrasion effectiveness of both the coatings are the surface roughness, the abrasive particle dimension, and the sliding speed. Full article
