Powder mixed electrical discharge machining (PM-EDM) is a technological advancement in (EDM) processes where fine powder added to dielectric improve the rate and surface quality. In this paper, of Nimonic-90 was carried out using fabricated PM-EDM, setup by adding silicon kerosene oil. The influence four input process parameters viz. concentration (PC), current (IP), spark on duration (SON), of...
Parameters Optimization of Electrical Discharge Machining Process Using Swarm Intelligence: A Review
Electrical discharge machining (EDM) can use soft tool electrodes to process hard workpieces achieve “soft against hard”, because it directly uses electrical energy and thermal remove metal materials. Then, generate complex features on harder materials meet the requirements of excellent surface quality. Since EDM involves many parameters, including non-electrical properties, is essential optimi...
saturated fat consumption increases the risk of both coronary and cancer diseases. therefore, fat reduction in uf-feta cheese (≈ 45% fdm) is favorable but, unfortunately, it has some negative effects on the texture and sensory characteristics of the cheese. in this research, response surface methodology was employed to study the probably improving effects of wpc80 (0-20 gr kg-1), lecithin (0-2 ...
response surface methodology (rsm) is a statistical method useful in the modeling and analysis of problems in which the response variable receives the influence of several independent variables, in order to determine which are the conditions under which should operate these variables to optimize a corrugated box production process. the purpose of this research is to create response surface mode...
Grey relational analyses are applied to determine the suitable selection of machining parameters for Wire Electrical Discharge Machining (Wire-EDM) process. The Grey theory can provide a solution of a system in which the model is unsure or the information is incomplete. Besides, it provides an efficient solution to the uncertainty, multi-input and discrete data problem. According to the Taguchi...
treated sea water is the most significant source of water and surfactant floods. the various chemicals employed in treatment plants should be compatible with surfactant systems. based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...
Background: Wire Electrical discharge machining (WEDM) has higher capability for cutting complex shapes with high precision for very hard materials without using high cost of cutting tools. During the WEDM process, the wire behaves like a metal string, straightened by two axial pulling forces and deformed laterally by a sum of forces from the discharge process. Major forces acting on the wire c...
Abstract In wire electrical discharge machining (WEDM), the erosion is made through a series of overlapped craters. The shape these craters has relevant impact on characteristics machined surface, from surface roughness to heat effects during spark. Current models EDM process do not represent specific WEDM characteristics, such as radial asymmetry crater or geometrical shape. order characterize...
in some conditions, to avoid deterioration and field losses of soybean seeds (glycine max merr.) from weathering at end of the season, farmers start to harvest seeds with a high moisture content and so, careful post-harvest drying would be required to maintain the physiological quality of seeds. response surface methodology (rsm) was used to optimize the operating conditions of soybean seed dry...
