What is the purpose of the abrasives in electrochemical grinding?

Abrasive materials, either diamond or aluminum oxide, are bonded to the grinding wheel, which allows the wheel to remove the oxide layers on the workpiece surface by abrasive action.

What are the advantages of EDM over other machining processes for profile cutting?

Advantages of Electrical Discharge Machining There is no direct contact between tool and work piece. Therefore, delicate sections and weak materials can be machined without any distortion. No burrs. Little or no polishing is required after the process is complete.

What are the advantages of EDM?

Advantages of EDM – part geometry

• Thin walls are possible.
• Cut internal corners with very small radii.
• Cut thin slots in extrusion dies with wire EDM.
• Produce blind and high aspect ratio pockets with sinking EDM.
• Produce non-round openings and cavities.
• An alternative to broaching for 2D shapes like gears.

How does electro discharge machining 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 advantages and disadvantages of ultrasonic machining?

Advantages and disadvantages of ultrasonic machining process

• This type of process produce less heat.
• You can do the machining of hard as well as brittle material in it.
• It can be used for non-circular holes drilling just like in glass.
• This may be use for hard materials threading.

Which of the following is the advantage of electrochemical machining?

Advantages of electrochemical machining: The rate of machining does not depend on the hardness of the work piece material. The tool does not wear. Soft materials (e.g., copper) may be used for tool fabrication.

What is the Not advantage of EDM?

Machining time is too long. Excessive tool wear. High specific power consumption.

What are the important applications of AJM?

Applications of AJM: The process is best suited for machining brittle and heat sensitive materials like glass, quartz, sapphire, ceramics, etc. It is used for drilling holes, cutting slots, cleaning hard substance deburring, polishing, etc. It is used for producing high quality surface.

Why ultrasonic machining process is used?

Advantages. Ultrasonic vibration machining is a unique non-traditional manufacturing process because it can produce parts with high precision that are made of hard and brittle materials which are often difficult to machine.

Where are ultrasonic machine are used?

Ultrasonic cleaners are used to clean many different types of objects, including jewelry, scientific samples, lenses and other optical parts, watches, dental and surgical instruments, tools, coins, fountain pens, golf clubs, fishing reels, window blinds, firearm components, car fuel injectors, musical instruments, …

What are the advantages disadvantages and applications of EDM?

Advantages and Disadvantages EDM

• Tolerances of +/- 0.005 can be achieved.
• Material hardness does not effect process – Tungsten Carbide – Stellite – Hastelloy – Nitralloy – Waspaloy – Nimonic – Inconel all can be successfully machined by EDM.
• Cutting complex shapes and thin walled configurations without distortion.

Which of the following industries use wire EDM for different applications?

Explanation: Industries such as chemical, aerospace, automobile, nuclear etc.., use wire EDM for a wide variety of applications in their industries.

What are the advantages and limitations of EDM process?

Advantages and disadvantages for EDM Machining

• Complex shapes can be produced while it is difficult to be machined by conventional Machining.
• Extremely hard material can be cut with tight tolerance.
• Good surface finish can be obtained.

What will happen if electrical discharge machining is done without any dielectric?

So basically, An EDM process must have a dielectric medium. Dielectric behaves as a channel between work and tool. If the dielectric is not present, it means there is no channel between work and tool. It is possible if we use machining inside the vacuum chamber but the tool wear will be high.

Which of the following materials is are used for electrical discharge machining EDM process?

2. Which of the following materials can be machined using Electro discharge machining? Explanation: EDM is used to machine materials such as carbides, heat resistant and super alloys which are difficult-to-machine materials.

Why dielectric fluid is used in EDM?

Dielectric is an important parameter in EDM and plays a crucial role in determining high material removal rate (MRR) and surface finish during operation. The dielectric fluid behave as a medium which controls the electrical discharge and absorb heat during process.
