Electrical Discharge Machine Working Principle. He noticed that the sparks had eroded some of the electrode material. However, with the modernization of technology and equipment, this technology is now integrated with computer numerical control (cnc).
Electrical Discharge Machine from ranamechanical.blogspot.com
The workpiece and the tool are electrically connected to dc electric power. It was first introduced by joseph priestly in 1770. The workpiece is fixed in the dielectric container using a fixture.
Material Removal Rate Occurs At The Spot Where The Electric Field Is Strongest.
Principle and possibilities amitabha ghosh department of mechanical engineering, indian institute of technology, kanpur 208 016, india present address: It is made up of an electric power supply, a dielectric medium, a tool, a workpiece. Electrical discharge machining technology is used to make molds and dies using a very strong cemented carbide material
The Difference Between Electrical Discharge Machining And General Machining Is That The Tool And Workpiece Are Not In Contact During Electrical Discharge Machining.
In this machining process both the work piece and tool must. The gap is varied from 0.01mm to 0. A certain amount of gap is maintained between the electrode tool and workpiece.
The Tool Is Fed Up By The Servo Feed Unit Which Can Move Downward In A Vertical Direction.
It was first observed in 1770 by joseph priestley. However, with the modernization of technology and equipment, this technology is now integrated with computer numerical control (cnc). It was first introduced in 1770 by joseph priestly.
Take Discharge As An Example:
The tool is the cathode. Electrical discharge machining(edm) is used to machine very hard materials. The workpiece and the tool are electrically connected to dc electric power.
The Tool And Workpiece Are Separated By A Small Gap Called A Spark Gap.
In edm machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes. In tool and mould making, edm is very. The power supply is given to the electrical discharge machining process i.e.
