What are the types of EDM process?
What is the Electrical Discharge Machining (EDM) process?
- EDM is a non-traditional manufacturing process that uses thermal energy to remove material from a workpiece as opposed to mechanical force.
- Electric discharge machining can be divided into three common types, Die sinking EDM, Wire EDM and hole drilling EDM.
What are the applications of EDM?
What are the applications of EDM?
- Drilling for micro holes in the nozzle.
- This is used in thread cutting.
- Used in wire cutting.
- Rotary form cutting.
- Helical profile milling.
What are the two types of EDM machines?
Below are the two main types of EDM machines:
- Conventional EDM Machines. Conventional EDM also goes by several other names, such as sinker EDM, die sinking, cavity-type EDM, volume EDM and ram EDM.
- Wire EDM Machines. Wire EDM, also known as spark EDM, wire burning and wire erosion, uses a thin heated wire as an electrode.
How does a wire EDM work?
Wire EDM machining works by creating an electrical discharge between the wire or the electrode and the work piece. As the spark jumps across the gap, material is then removed from the work piece and the electrode.
How are EDM electrodes made?
The EDM process uses custom machined electrodes (typically made from graphite or copper) which creates a spark between the material being machined and the electrode. The spark erodes material in the EDM tools pathway, creating the complex cavities or shapes desired.
Which of the following are main components of EDM?
Which of the following are main components of EDM? Explanation: Main components of machining system in EDM are – dielectric system, power supply and servomechanism.
What are the various flushing techniques used in EDM?
There are four types of flushing: pressure, suction, external, and pulse flushing. Each job needs to be evaluated to choose the best flushing method. Pressure flushing, also called injection flushing, is the most common and preferred method for flushing.
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.
How wire EDM is different from EDM?
Conventional EDM cannot produce narrower angles or more complex patterns, while wire-cut EDM can be performed. A more precise cutting process allows for more complex cuts. The wire EDM machine is capable of cutting a metal thickness of about 0.004 inches.
What are the different types of electrode materials used in EDM tooling?
Electrodes that are generally used in EDM process are copper, graphite, copper tungsten, silver tungsten, tungsten carbide, brass.
What is electronic distance measurement (EDM)?
Electronic distance measurement (EDM) is a method of determining the length between two points using electromagnetic waves. EDM is commonly carried out with digital instruments called theodolites. EDM instruments are highly reliable and convenient pieces of surveying equipment and can be used to measure distances of up to 100 kilometers.
What is EDM and how does it work?
EDM is commonly carried out with digital instruments called theodolites. EDM instruments are highly reliable and convenient pieces of surveying equipment and can be used to measure distances of up to 100 kilometers.
What is electronic direct mail (EDM)?
Electronic Direct Mail, or EDM, is an email marketing tool that revolves around building an email database of customers and prospects. It involves directly sending timely, relevant promotions via email that keep your company in front of your audience until they are ready to engage your service.
