  • experimental investigation for performance study of wire electrochemical Spark Cutting of silica epoxy nanocomposites
    Silicon, 2020
    Co-Authors: Pallvita Yadav, Vinod Yadava, Audhesh Narayan
    Abstract:

    Polymer Nanocomposites are advanced engineering composites with enhanced properties. These materials play a central role in various industrial sectors. The growing awareness of the key parameters (which influence the physical properties) with different combination of matrix-reinforcement, are making them more attractive in various applications. Machining of these materials is a challenging task for engineers with their properties (hardness and brittleness) due to various combinations of matrix-reinforcement. Therefore, the aim of present work is to investigate the machining behaviour of Silicon Dioxide (silica) Epoxy Nanocomposite due to straight Cutting by using Wire Electrochemical Spark Cutting (WECSC) process. A specific number of experiments were conducted based on one parameter at-a-time approach to study the effect of influencing input parameters. The effect of various process parameters namely voltage supply, electrolyte concentration, wire velocity, pulse-on time and silica particle concentration (Cp) such as 3%, 4% and 5% (weight percent) on performance measures such as material removal rate (MRR) and surface roughness were demonstrated experimentally. WECSC has been found effective technique for Cutting of Silicon Dioxide Epoxy Nanocomposite. It is reported that MRR increases with decrease in silica particle concentration in Silicon Dioxide Epoxy Nanocomposite.

  • experimental investigation of kerf characteristics through wire electrochemical Spark Cutting of alumina epoxy nanocomposite
    Journal of Mechanical Science and Technology, 2018
    Co-Authors: Pallvita Yadav, Vinod Yadava, Audhesh Narayan
    Abstract:

    Alumina epoxy nanocomposite (AENC) is an emerging class of composites with a wide range of functionality and applicability; however, managing AENC using a machine is difficult because of its special mixed characteristics. The presence of extremely hard alumina particles in soft epoxy matrix enhances material properties. The present work investigates the kerf characteristics of a straight cut made in AENC through Wire electrochemical Spark Cutting (WECSC) process. The kerf characteristics, such as kerf deviation and taper, are used to measure the cut quality. The applied voltage, electrolyte concentration, wire velocity, pulse on-time and pulse off-time are varied, and their effects on the kerf characteristics are experimentally investigated in a developed setup. Influencing parameters for straight Cutting of AENC are applied voltage, concentration of electrolyte and wire velocity.

  • PRINCIPLES AND APPLICATIONS OF Spark MACHINING
    2016
    Co-Authors: D. W. Rudorff
    Abstract:

    The historical background of electro-erosion technique is briefly outlined and the difference between Spark and arc discharges is defined. The underlying principle of the relaxation-type Spark circuit as employed in industrial machines is explained, and development trends are discussed. The various factors bearing upon the efficiency of Spark-erosion operations are enumerated. The mechanical features of a typical Spark-erosion machine are described, and the range of machining operations for which Spark Cutting machines can be designed, is outlined. Typical samples of work produced on a commercial unit are described and illustrated, and the properties of Spark-machined surfaces are discussed. HISTORICAL SURVEY WHILE the erosion of materials by Spark discharge had already been observed by Priestley in 1762, first use of Spark discharges for the disintegration of metals in the form of small particles was carried out by Svedberg (1906)t who employed oscillatory Spark circuits to produce colloidal solutions by the electric pulverization of the Spark gap electrodes immersed in liquid.

  • INFLUENCE OF LASER Cutting AND PUNCHING ON MAGNETIC PROPERTIES\nOF ELECTRICAL STEEL M470-50A
    2016
    Co-Authors: Bulín Tomáš
    Abstract:

    Electrical steel M470-50A belongs to the most often used materials in electrical machines. Due to this fact, it is desirable to know the magnetic parameters after processing raw sheets into the required shape. Basic parameters of mechanical, electrical, and magnetic properties of the sheets are usually obtained from the producer but the magnetic properties are changing in dependence on additional machining processes. The aim of this study is to describe changes in parameters of magnetic behavior after punching, laser and Spark Cutting of the original sheets. The basic information of structure was obtained by optical and scanning electron microscopy. The magnetic parameters were acquired from the measuring of magnetic hysteresis loops in dependence on saturation fields and frequencies. The results are discussed from the point of view of applied\nCutting technology with the aim to obtain the best magnetic parameters and consequently a higher efficiency of the final product. Results can be used as input parameters in simulation of the electrical machine
