What materials can be machined by EDM?

What materials can be machined by EDM?

In general, every conductive material can be machined with electrical discharge machining. Common materials include metals or metal alloys such as hardened steel, titanium, and composites. Typically, the electrodes for die sinking EDM are made of copper or graphite.

What is electrical discharge machining used for?

EDM is a thermal process for removing unwanted material by applying cycled discharging sparks in the gap between an electrode and a conductive workpiece. This method is typically used for machining refractory metals and hard materials, which are difficult to machine with conventional machining techniques.

Which of the following materials can be machined using electric discharge machining?

Which of the following material can be machined using electronic discharge machine? Explanation: Iron is a good conductor of electricity and hence can be machined using electronic discharge machine.

Which material Cannot be machined by EDM?

Explanation: Wood is a bad conductor of electricity and hence cannot be machined using electronic discharge machine.

Can you EDM stainless steel?

CNC controlled cutting patterns can be completed quickly on a wide range of stainless steel alloys, while maintaining a low Ra surface roughness. EDM can cut material thickness from only a few thousandths of an inch to several inches.

What are the types of electrical discharge machining?

Electric discharge machining can be divided into three common types, Die sinking EDM, Wire EDM and hole drilling EDM.

What is electrical discharge machining and how does it work?

Electrical Discharge Machining (EDM) is a controlled metal-removal process that is used to remove metal by means of electric spark erosion. In this process an electric spark is used as the cutting tool to cut (erode) the workpiece to produce the finished part to the desired shape.

What are the methods of dielectric flushing?

Various methods for dielectric flushing: (a) suction through electrode (b) suction through workpiece, (c) pressure through velectrode, (d) pressure through workpiece, (e) jet flushing, (f) periodic cycling of electrode [Courtesy: HMT, Bangalore, India]

Which one is the correct with respect to electric discharge machining?

Explanation: Electro Discharge Machining (EDM) In electro discharge machining the metal is removed by erosion caused by rapidly recurring spark discharges between the tool (cathode) and work (anode) separated by flooded dielectric fluid through a small gap.

Which of the following shape can be produced using electro discharge machining?

Process Shape (Job) Application
Ultrasonic Machining Round and irregular holes, impressions
Abrasive jet Machining Drilling, cutting, deburring, etching, cleaning
Electric discharge machining Blind complex cavities, micro holes for nozzles, through cutting of non-circular holes, narrow slots.

Can you EDM plastic?

Virtually any material that is conductive is a perfect one for wire EDM, and it includes all the metals. DEK’s wire-cut EDM equipment also can machine plastic, metal alloys, exotic and precious metals.
