The influence of conditions and the sifting process efficiency of the worn-out polymeric abrasive paste containing silica (SiO2) and polymer chips remaining after the surface treatment were investigated. The abrasive paste regeneration process consisted of sifting the used paste through sievesof a vibrating screen, on which abrasive grains and polymer chips were recovered. The diameter of the sieve holes determined the size of the recovered abrasive grains and polymer chips, on the size of which the efficiency of the process depended. The lowest efficiency of the sifting process was obtained using a sieve with the holes diameter equal to the diameter of the grain and the polymer chips of thegiven fraction. The highest efficiency of the sifting process was obtained for a sieve with a diameter of 0.032 mm. The regenerated polymeric abrasive paste can be reused in the process of abrasive flow machining.

“…The tests were carried out by varying the cutting speed between 23.6 and 47.1 m/min, maintaining the feed speed at 30 mm/min, axial depth of cut at 75 µm, and radial depth of cut at 500 µm, and varying the feed speed from 30 to 90 mm/min, maintaining the cutting speed at 55 m/ min, axial depth of cut at 75 µm, and radial depth of cut of 500 µm. Also, dry cutting conditions were investigated and using MQL, lubricant used in this study was a vegetablebased high-performance cutting oil with a density of 0.99 g/ cm 3 and viscosity of 58mm 2 /s. Among the results analyzed, the authors evaluated the influence of cutting speed, feed per tooth, and dry or lubricated cutting condition (MQL) on the surface quality of the machined part.…”

“…The AM process involves the direct manufacturing of components working from their digital representation, based solely on computer-aided design (CAD) 3D models. According to Gusarov et al [2], one of the great advantages of AM is the reductions in the material and logistical tasks required to manufacture a part compared to traditional processes; Kum et al [3] and Murr et al [4] referred to the AM capacity to economically produce complex geometries with internal features; Renjith et al [5] highlighted the design freedom offered by AM; Nagalingam et al [6] mentioned the possibility of using AM for optimizing engineering components; and Tan et al [7] pointed out that AM can eliminate specialized tools and fixtures in some cases.…”

Metal additive manufacturing (MAM) has attracted significant interest in both academia and industry to produce near-netshape engineering components. The inherent defects in MAM, however, require suitable subtractive techniques as postprocesses to control dimensional and geometric tolerances as well as surface finish. The additively manufactured metals, with different microstructures than the wrought materials that produced by conventional routes, need different approaches and parameters when being machined. This review covers recent published literature on traditional micro-machining as a post-processing operation for MAM and recommends future directions. The text presents a brief review on the main AM processes followed by a comprehensive conventional micro-milling and microdrilling, as well as applications for micromachining. Micro-tool assessment, built-up-edge prediction and prevention, and link of macro/micro-machining are areas for future research.

“…In turn, when the geometry is complex, more advanced machine configuration and CNC code generation are required, which increases processing time (Boschetto et al , 2016). Abrasive flow finishing and Abrasive jet deburring had a greater effect on final roughness, but small dimensional changes occurred due to material removal (Kum et al , 2020).…”

Purpose Fused filament fabrication or fused deposition modeling (FFF/FDM) has as one of its main restrictions the surface quality intrinsic to the process, especially linked to the layer thickness used during manufacture. The purpose of this paper is to study the possibility of improving the surface quality of polylactic acid (PLA) parts manufactured by FFF using the shot blasting technique. Design/methodology/approach The influence of corundum blasting on 0.2 mm layer thickness FDM PLA parts treated with two sizes of abrasive, different exposure times and different incidence pressures. Findings As a result, improvements of almost 80% were obtained in the surface roughness of the pieces with high exposure times, and more than 50% in just 20 s. Originality/value This technique is cheap, versatile and adaptable to different part sizes and geometries. Furthermore, it is a fast and environmentally friendly technique compared to conventional machining or vapor smoothing. Despite this, no previous studies have been carried out to improve the quality of this technology.
