Vibration-assisted machining has been proven as an excellent material-removal process with its multiple advantages over ordinary methods. However, the is usually applied for of easy-to-cut materials and conventional cutting tools vibrating, at or below ultrasonic frequency. This study was conducted to evaluate effect vibration ball end mill objective enhance machinability difficult-to-cut material. An analytical model established calculate forces generated during process. A WC-Co-based...
The introduction of external surface features on mating contact surfaces is an effective method to reduce friction and wear between the surfaces. tribological properties can be improved by controlling geometrical parameters (shape, size, depth) texture effectively. In present study, Al6061-T6 cylindrical workpieces with various micro-dimple-texture geometries AISI 52100 steel stationery block are tested experimentally, in a rotating cylinder-on-pin configuration test. dual-frequency...
The aim of the study was to improve mechanical, biodegradation and in vitro biocompatible characteristics as received rolled AZ31 (Mg-1%Zn-3%Al) alloy by develop surface composite Mg-Titania. developed friction stir processing (FSP) it's used for prosthetic applications. influence tool rotation speed number FSP passes on grain structure, refinement, tensile strength, hardness, degradation rate biocompatibility were explored. obtained results support capability terms mechanical strengthening,...
Predicting the susceptibility of rockfall mountain hazards for block-in-matrix soils is challenging critical steep cuts. This research illustrates a hydrogeotechnical approach prediction triggering by performing laboratory tests on low-cohesive-matrix soil collected from slopes with 85° to 88° angles at Tatta Pani site, Karakorum Highway (KKH), and then real-scale moisture-induced was conducted site validation data. Laboratory data forty quick direct shear samples field depicted 3-fold drop...
Electrical discharge machining process is a material removing method that based on the principle of erosion work surface by electrical sparks produced high-density current supply. The usually applied difficult-to-machine metals with high conductivity, which have some mechanical properties affecting machinability negatively, or very complex shapes. These situations make it necessary to closely control and check influence parameters resulting output, in form removal rate (MRR) roughness. most...

ABSTRACT Corrosion is a natural phenomenon that gradually deteriorates any material. Mild steel structures are quickly corroded by the sea environment, and thus protective coatings normally used to prevent corrosion. In this study, atmospheric plasma spray (APS) detonation gun (DGun) deposit nichrome on duplex stainless (DSS 2205). The coated samples were immersed in 3.5 % sodium chloride solution perform electrochemical corrosion studies. Microstructural characterization was performed...
Abstract Machining of difficult-to-cut materials with high surface quality is a challenging task that requires precise machining approach an efficient cutting tool. Among the tool performance evaluation parameters, rate wear, chip morphology and are vital aspects to establish relationship between input conditions quality. In this study, geometrical parameters i.e. rake, clearance helix angles were selected analyse effect geometry on wear behavior during ball end milling steel. Increase in...
Abstract In the 2D-Vibration Assisted Cutting (2D-VAC) method, cutting tool shakes in a 2-dimensional approach because of superimposed high-frequency modulation. This modulation effect creates displacement at tiny scale micrometers and causes an escalation resultant speed. Consequently, 2D-VAC has superior advantages compared to traditional (TC). manuscript describes research on that focuses modeling forces (mathematical model) finite element analysis (FEA) results. The FEA results are...
