“…The optimum parameters that was used to achieve this improvement were feed rate of 15000 mm/min, spindle rotational feed of 900 rpm, 15% shear thickening fluid and 0.8 mm working gap. Li et al [159] showed that the shape of the magnetic head had significant influence on the performance of MAF when used for surface polishing of 1 mm Ti-6Al-4V wire. They investigated different taper angles (0, 25, 35°) and found that at taper angle of 37°, tool speed of 800 rpm, processing time of 300s and abrasive particle size of 178 mm, the surface roughness of 1 mm Ti-6Al-4V wire was reduced to 0.28 mm from 0.9 mm.…”

Machining is one of the major contributors to the high cost of titanium-based components. This is as a result of severe tool wear and high volume of waste generated from the workpiece. Research efforts seeking to reduce the cost of titanium alloys have explored the possibility of either eliminating machining as a processing step or optimising parameters for machining titanium alloys. Since the former is still at the infant stage, this article provides a review on the common machining techniques that were used for processing titanium-based components. These techniques are classified into two major categories based on the type of contact between the titanium workpiece and the tool. The two categories were dubbed conventional and non-conventional machining techniques. Most of the parameters that are associated with these techniques and their corresponding machinability indicators were presented. The common machinability indicators that are covered in this review include surface roughness, cutting forces, tool wear rate, chip formation and material removal rate. However, surface roughness, tool wear rate and metal removal rate were emphasised. The critical or optimum combination of parameters for achieving improved machinability was also highlighted. Some recommendations on future research directions are made.

With the rapid development in the industry, applications of finished parts are increasing day by day. However, the surface finish of the parts fabricated by conventional processes could not readily meet the requirements of various applications. Therefore, post-processing is needed to further improve the surface quality. Magnetic abrasive machining uses a flexible magnetic abrasive brush to remove material from the workpiece surface at a controllable rate. This cutting tool sticks to the workpiece during finishing operation and exerts a small force on the surface. In magnetic abrasive machining, the cutting tool neither requires compensation nor dressing. In this paper, the internal finishing of aluminum pipes has been investigated in magnetic abrasive machining tests using silicon carbide-based glued magnetic abrasives. For evaluating the performance of these magnetic abrasives, experimental work according to the central composite design technique was carried out to finish the aluminum pipes. The results so obtained were analyzed to study the influence of process parameters like magnetic field strength, speed of workpiece, abrasive mesh size and quantity of magnetic abrasives on percentage improvement in surface finish and material removal rate. The analysis showed that magnetic field strength was the most effective parameter while finishing the aluminum pipe followed by the quantity of magnetic abrasives. The finishing at optimal condition resulted in a surface finish of 0.07 μm. Further, scanning electron microscopy of the surface before and after magnetic abrasive machining was taken to study the improvement in surface finish. HIGHLIGHTS Magnetic abrasive machining (MAM) of aluminum work specimens have been performed by SiC-based magnetic abrasives The central composite design has been used for planning and execution of experiments The surface finish and material removal rate of the machined work specimens have been analysed as a performance measure of MAM process The high value of improvement in surface finish and material removal rate at optimum machining conditions have been observed Scanning electron microscopy (SEM) has been employed to study the surface topography of machined surfaces GRAPHICAL ABSTRACT

“…Magnetic abrasive finishing is used in different kinematic variations for machining flat surfaces [1][2][3][4][5][6][7][8][9][10][11], shafts [12][13][14], thin-walled tubes [15][16][17][18][19], wires [20,21], cutting tools [22][23][24] and freeform surfaces [25][26][27]. However, this usually requires separate equipment, which increases the time and costs involved.…”

Magnetic abrasive finishing (MAF) shows a high potential for use on computerized numerical control (CNC) machine tools as a standard tool to polish workpieces directly after the milling process. This paper presents a new MAF tool with a single, large permanent magnet and a novel top cover structure for finishing the plain ferromagnetic workpieces. The top cover structure of the MAF tool, combined with an optimized working gap, ensures the effect of mechanical powder compaction, which leads to a significant increase in process capability and surface roughness reduction. The influence of the process parameters such as feed rate, equivalent cutting speed, working gap (including for three grain sizes) and the gap to the magnet was investigated. In addition, the influence of the initial surface after face milling, end milling, ball end milling and grinding on the surface quality after MAF was investigated. Furthermore, three typical surfaces after milling and MAF were analyzed. By magnetic abrasive finishing, a significant surface quality improvement of the initial milled surfaces to roughness values up to Ra = 0.02 µm and Rz = 0.12 µm in one processing step could be achieved.
