What are the differences between wire electro discharge machining and conventional electro discharge machining?

Wire EDM uses a thin wire to remove surrounding material, where conventional EDM uses a shaped electrode to remove material.

What is fullform of PWM?

PWM stands for Pulse Width Modulation. It is a technique used in electronics to encode information in a pulsing signal. In PWM, the duration of a pulse in a waveform is varied to convey information. This method is commonly used to control the power delivered to electrical devices, such as motors, LEDs, and other components, by adjusting the average power over time.


How EDM wire cut machine works?

in wire cut, a wire is passed through a metal or is placed next to it. the wire works as one of the electrodes while the work piece would be the other one; using andielectric liquid to isolate the wire from the work piece. the electricity is conducted in the wire. as the wire gets closer to the work piece the electricity (electrons) tend to jump from the wire to the work piece in order to create a complete electrical circuit that's when a spark is formed. the dielectric helps us by isolating the wire from the work piece as long as it can, so we can have enough difference in potential between two electrodes before the spark is formed, it works like capacitor stopping the current from going through it until it collapses at a potential and enough current passes through at once. A collateral effect of this passage of current is that material is removed from both the electrodes.
