Optimization of Electrical Discharge Machining ( E D M ) Process Parameters Using Soft Computing Techniques : a Review
ABSTRACT
Electric Discharge Machining (EDM) is a thermo-electric non-traditional machining process in which material removal takes place through the process of controlled spark generation between a pair of electrodes which are submerged in a dielectric medium. Due to the difficulty of EDM, it is very complicated to determine optimal process parameters for improving machining performance. It relies on heuristics, which are not easy to model, and based on the experiences of specialists. A proper selection of machining parameters for the EDM process as per the operator’s requirement is very much difficult because of their numerous and diverse range. So, in order to approximate the EDM performances, -------------------------------------------------

    Unconditional Positive Regard is a central concept in the theories of Carl R. Rogers, both for psychotherapy and for interpersonal relations. A universal need for positive regard by others appears at about the same time a person begins to experience awareness of self (Rogers, 1959). In therapy, UPR is a quality of the therapist’s experience toward the client (p. 239). Rogers’ writing sheds light on various aspects of this construct:…

    Surface roughness of parts produced by conventional machine tools, depends n the machine tool system and the cutting process. It is difficult to produce a smooth surface on complicated profiles at an economic cost by using conventional machining processes. This and the advent of new ‘ difficult-to-machine’ materials like hardened steel, nickel, cobalt, titanium alloys, ceramics, glass, etc., have necessitated the need for new machining techniques.…

    A machine tool is a machine for making components of a given shape, size and accuracy as per the requirements by removing material from the workpiece by using a cutting tool to operate upon the workpiece. Machine tools are capable of producing themselves therefore the machine tools are quite often referred to as mother machine. In the manufacturing processes, machine tools are the most versatile and almost any product can be produced with them. The machine tools should able to fulfill the following requirements:…

    Cutting and trimming of CFRP laminates with high dimensional accuracy is highly essential for applications like aerospace industry. Non-conventional machining techniques provide a good solution for this problem in which automation, precision and dimensional accuracy can be easily achieved. Among them, Abrasive Water Jet cutting proves to be a promising area since there is no possibility of thermal damage to the material. AWJ cutting belongs to the mechanical group of non-conventional techniques which uses the mechanical energy of water and abrasives to perform the material removal process. Water is pumped at a high pressure and abrasive is added to the stream in such a way that the momentum of water stream is transferred to the abrasives. Hence, the abrasive gets accelerated to a speed high enough to cut very hard materials. In the present work, an attempt has been made to…

    INTRODUCTION TO MILLING

    • 1021 Words
    • 4 Pages

    Milling is a process in cutting away materials such as aluminium by feeding the workpiece into a revolving cutter.The cutting method of the many teeth around the milling cutter provides a fast action of machining. The machining surface may be plane surfaces, parallel or right angled to base surface. Milling can also be used to produce irregular surfaces and can used to drill, bore, cut gears and produce slots. Milling machine is responsible for holding the work piece, rotating the cutter and also feeding in the material or work piece. The work piece on the bed can be fed into the miling machine by the x,y,z axis manually. Most milling machine are equipped with power feed. Power feed provides smoother surface finish compared to the manual feed. Besides power feed is more efficient on long cuts compared to manual ones. On some machines, the power feed is controlled by a forward reverse lever and a control speed knob.…

    Grind

    Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is on the order of 0.000025 mm, in most applications it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth. However, there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus, grinding is a diverse field.…
