Optimization 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...
متن کاملApplication of Grey Relational Analysis to Machining Parameters Determination of Wire Electrical Discharge Machining
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...
متن کاملA Review on Abrasive Waterjet and Wire Electrical Discharge Machining – High Speed
Technological advancement, on the one hand, makes Electrical Discharge Machining (EDM) much faster. One example of that is the presence of Wire Electrical Discharge Machining – High Speed (WEDM-HS) machine, which makes the material removal rate as high as 80 mm/min. On the other hand, it also make Abrasive Waterjet (AWJ) achieve much better quality surface and tighter tolerance. As a result, th...
متن کاملParametric Optimization for Surface Roughness in Wire Electrical Discharge Machining— A Taguchi Approach
High carbon high chromium alloy tool steels (D-3) with excellent abrasion resistance (HRC: 58-65) are increasingly used in manufacturing high performance cutting tools (dies and punches), blanking and punching tools, extrusion tools, etc. Being a hard material, it is difficult to machine using conventional machining methods. Wire Electric Discharge Machine(WEDM) seems to be a viable option to m...
