“…Ra is the most important index to evaluate surface roughness. Many studies have been carried out on the theoretical model of surface roughness [ 34 , 35 , 36 , 37 ]. Like turning, reaming is a type of continuous cutting, which means that the cutting amount is uniform and the cutting resistance is uniform, and the cutting edge is in contact with the workpiece at all the time during the process of machining, as is shown in Equation (3) [ 38 ].…”

Titanium alloys have been extensively used in practical machining owing to their outstanding mechanical properties, high specific strength and low thermal deformation. In this study, the cutting experiments are carried out on Ti6Al4V material with right-hand and straight cemented-carbide groove reamers. The experimental results show that the cutting force with the right-hand reamer is smaller compared to straight groove reamer due to the groove structure. The main tool wear forms are micro-chipping, adhesive wear, abrasive wear, and coating falling off on the right-hand reamer, while there is a built-up edge and serious damage failure on the cutting edge of the straight groove reamer. Notch wear and pitting on the surface of the hole wall are mainly caused by chip adhesion and tool wear. The surface-roughness value is the lowest as the cutting speed is 60 m/min and the feed rate is 0.4 mm/rev. The holes machined by the right-hand reamer have a low hole diameter deviation with various cutting parameters. The geometric accuracy of cylindricity is higher as the feed rate is 0.4 mm/rev and the cutting speed is 40 m/min for both kinds of reamers, and the cylindricity is better with the right-hand reamer.

TB2 titanium alloys are widely used in the aerospace industry. A high surface quality is required for the performance and fatigue life of titanium alloy parts. Electropolishing is useful for thin metal plates owing to its good processability and conformability. In this study, electrolyte ushing was proposed for electropolishing a large surface and a NaCl-containing ethylene glycol electrolyte was adopted. Three different mechanical grindings were employed for pretreatment, and the ideal surface quality was obtained with a rubber grinding head. Therefore, in the process of electropolishing a large surface, electrolyte ushing is superior to stirring because its ow eld is even and controllable. The effects of the main processing parameters (voltage, ow rate, and process time) on the surface roughness and morphology were studied. Finally, a mirror-like surface with a surface roughness of 10.5 nm was obtained after ushing electropolishing for 30 min under a voltage of 25 V and a ow rate of 0.84 m/s.
