“…The polishing of aluminum tube surface using white alumina (WA) powder #10000 (diameter 0.5 mm~0.7 mm) could achieve R a = 0.030 mm at maximum roughness due to abrasive limitations. In the previous research, where the diamond particle diameter 0.05 mm was used in the second finishing stage, aluminum tube internal surface was finished up to R a = 0.020 mm which required 40 min of processing time [22].…”

In this research, we studied the effects of electrolysis in the magnetic abrasive finishing of an AA6063-T1 tube internal surface. The finishing surface's hairline morphology was removed in a short time by physical characteristic transformation of the finishing surface in which the aluminum oxide film was formed during the electrolysis. Next, magnetic abrasive finishing was used to eliminate the oxidation layer and polish the surface to a mirror-finishing standard. The two-step process effectively improved the surface roughness in a shorter time. The morphology changes before and after the finishing process, was studied by surface roughness measurement and scanning electron microscope photographs. Notably, the pit or micro holes formation during the electrolysis on the aluminum oxide film was examined and its effect on the surface roughness was studied. The elements' residual on the surface was investigated by X-ray photoelectron spectroscopy analyzer before and after the process to confirm the formation and removal of oxidation film on the finishing surface. The lower value for torque measurement in electrolysis combined process compared to the conventional method was due to the porous characteristic of aluminum oxide film.Keywords: Electrolytic magnetic abrasive finishing / finishing mechanism / aluminum tube finishing / finishing torque / surface roughness In dieser Studie wurden die Auswirkungen der Elektrolyse in der magnetischen Schleifbearbeitung einer AA6063-T1-Rohrinnenoberflä che untersucht.

“…Consequently, high process residual tensile stresses arise in the material of the component surface layer, and a large number of burns appears on the surface, which significantly reduces the performance properties of the component. The available ways to improve the performance indicators of abrasive tools for machining components from chrome-nickel steels and alloys associated, for example, with designing special grindstones [1][2][3][4][5] or with the activation of the used cutting/cooling process media [6][7][8][9][10], are often expensive and do not always provide the required quality of the component surface layer, as they are most often meant for processing low-alloy steels. Thuswise, a wide use of the components made of hard-to-treat chrome-nickel steels and alloys in the modern aircraft engine-building, generates a need for manufacturing cheap and efficient abrasive tools.…”

The technology of obtaining an abrasive tool on a ceramic bond for surfacing components made of chrome-nickel steels and alloys including the composition of the abrasive mass with wood flour, and the process of tool impregnation with an aqueous solution of chrome diiodide are considered. The comparison results on the efficiency of grindstones made according to the developed technology with their redress life between two consecutive shapings, and the performance quality indices of the processed component surfaces are presented. An empirical dependence of the efficient grindstone life between two consecutive shapings on the component speed, length feed, infeed movement, and the chrome diiodide saturation in the impregnated grindstone, is obtained. It can be used by production managers to optimize the modes of surfacing components from chrome-nickel steels and alloys providing the required performance quality indices. The mechanism of loss of function of the grindstone impregnated with chrome diiodide is considered.

Abstract.This paper investigates the wear mechanism of WC (tungsten carbide) drills in drilling titanium alloy (Ti-6Al-4V) with graphene oxide suspended cutting fluid and conventional coolant. By analysing cutting forces and examining the worn surface of the drills, wear progression in the cutting experiments were discussed. A significant reduction in cutting force and tool wear was found in cutting Ti-6Al-4V with graphene oxide suspended cutting fluid compared to conventional coolant. The causes led to such changes were presented. IntroductionTitanium and its alloys have been widely used in automotive, aerospace and biomedical industry owing to their excellent properties including high tensile strength and toughness, light weightstrength ratio and extraordinary corrosion resistance. However, Titanium alloys are difficult to machine due to their low thermal conductivity and high chemical activities. A lot of research had been conducted to reduce cutting temperature in order to increase tool life and improve machining efficiency. For example, Minton et al.[1] investigated indirect cooling with a diamond-coated internally-cooled cutting tool whilst machining titanium. Yamaguchi et al. [2] found that magnetic abrasive finishing of cutting tools could reduce cutting heat in machining of titanium alloys, because of the reduction in friction at the chip-tool interface and thus extend tool life. Huang et al.[3] investigated the drilling of SiCp/Al metal matrix composite with PCD tools and found the higher the cutting speed, the better the surface finish. Recently, various attempts to reduce tool wear have been made by using different coolants such as liquid nitrogen, powder suspended oil and water. For example, Davim and Mata [4] found that cryogenic cooling had substantially reduced the grinding zone temperature. However, due to the limited improvements achieved, these technologies have not been widely applied in practice. Graphene is a thin layer of pure carbon; it is a single, tightly packed layer of carbon atoms that are bonded together in a hexagonal honeycomb lattice. It is the best-known two-dimensional material, with its atom-thick layers proving plenty of fascinating material properties. One of the outstanding properties is its excellent thermal conductivity: the thermal conductivity of suspended graphene oxide is as high as 5300 W⋅m −1 ⋅K −1 [5], this makes for graphene oxide suspensions an excellent media which can be applied as cutting fluid [6]. Chu et al.[7] developed a canola-based cutting oil enhanced with graphene platelet (GPL) additives for high performance micro-machining applications, and found that graphene colloidal suspensions was an excellent alternative cutting fluid in reducing cutting temperature. In the past decades, graphene based cutting fluids had been tried in many applications for the machining of steel materials [8]. However, little research has been done to use graphene oxide powder suspended cutting fluid to drill titanium alloy, and it is unclear how the effects of graphene oxide s...
