Influence of Electrical Resistivity and Machining Parameters on Electrical Discharge Machining Performance of Engineering Ceramics
Engineering ceramics have been widely used in modern industry for their excellent physical and mechanical properties, and they are difficult to machine owing to their high hardness and brittleness. Electrical discharge machining (EDM) is the appropriate process for machining engineering ceramics provided they are electrically conducting. However, the electrical resistivity of the popular engine...
متن کاملOptimization of Machining Parametric Study on Electrical Discharge Machining
Abstract—Productivity and quality are two important aspects that have become great concerns in today’s competitive global market. Every production/manufacturing unit mainly focuses on these areas in relation to the process, as well as the product developed. The electrical discharge machining (EDM) process, even now it is an experience process, wherein the selected parameters are still often far...
متن کاملOptimization of machining parameters and wire vibration in wire electrical discharge machining process
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...
متن کاملMicro Wire Electrical Discharge Machining , Main Aspects , Tools And
The increasing demand of micro or miniature parts and the development of the micro machining processes are the cause of the growing of micro wire electrical discharge machining (μ-WEDM). μ-WEDM has the ability to manufacture complicate shapes with high accuracy and provides the advantage of machining any conductive materials regardless of their mechanical properties in the absence of significan...
