(PDF) Jet Electrochemical Micromachining of Micro-Grooves

May 30, 2020 · In this paper, a method of electrochemical machining using a conductive masked porous cathode and jet electrolyte supply is proposed to generate micro-grooves with high machining BJNANO - An investigation on the drag reduction Jan 03, 2020 · (3) The pipeline with appropriate microgrooves had a drag reduction effect at a certain flow rate, and a maximum DRR of 3.21% was achieved in the annulus flow experiment at a flow rate of 2.4 × 10 3 m 3 /s. (4) The CFD model predictions were in good agreement with the experimental results in terms of the influence of the Reynolds number on

Effect of Sulfate Concentration on Surface Roughness on

Effect of Sulfate Concentration on Surface Machining success is also not dependent on the material hardness, so very hard materials, such as super alloys, can be easily machined (1). High surface finishes can be of microgrooves fabricated by electrochemical micromachining. Proc Inst Mech Eng Part B Effect of hybrid texture combining micro-pits and micro Feb 13, 2016 · Abstract. Friction at the tool-chip interface may be reduced by introducing a lubricant into the tool-chip interface; the effectiveness of which can be enhanced by surface texturing the tool. Micro-grooves, micro-pits, and hybrid texture combining micro-pits and micro-grooves were fabricated employing laser on the rake face of carbide tools, with a view to facilitating lubricant penetrate and Experimental investigations into machining accuracy and Microgrooves are one of the basic microfeatures fabricated on different microproducts, used to integrate micro systems in various fields. Service life and product functioning of microproducts are directly influenced by shape, size, and surface quality of microgrooves fabricated on it.

Fabrication of microscale concave and grooves through

Jan 01, 2019 · The difference in machining depth is proportional to the machining time per unit area. When the machining time per unit area increases, the machining depth also increases, whereas the relative current density and effective electric field range decrease, halting any change in the groove width.

Journal of The Japan Society of Electrical Machining EngineersMicrogrooves of 60m depth and 565m width were fabricated by electrolyte jet machining. The results of forming showed that the air vents are effective in improving the


generated in surface layer of a workpice in result of pre-determined contact S. Ponka, P. Zyzak roller) with machined surface [1]. Actually, one develops a series of kinematics solutions of machining systems and tools to the burnishing. Methods of the it is possible to generate various systems of the microgrooves on machined Micro form rolling:Imprinting ability of microgrooves on May 26, 2008 · FDBs have V-shape microgrooves (herringbone grooves) 520 m deep engraved on the shaft or sleeve, and dynamic pressure is generated in the microgrooves when the spindle rotates (Geiger et al., 2001). The microgrooves on the shaft of FDBs are generally made by machining, electric-discharge machining or etching; however, these manufacturing processes are time-consuming.Fabricating microgrooves with varied cross-sections by generate microgrooves on metals, ceramics and glasses, Microcutting is one of the most effective techniques for machining microgrooves on metals and single crystalline materials [510]. End milling [5, 6], shaping [7, 8], fly cutting [9], and diamond turning [10] are four popular effect is expected to take place. As schematically
