Principle and Working of MILLING MACHINE - …

Introduction: Milling is the cutting operation that removes metal by feeding the work against a rotating, cutter having single or multiple cutting edges. Flat or curved surfaces of many shapes can be machined by milling with good finish and accuracy. A milling machine may also be used for drilling, slotting, making a circular profile and gear cutting by having suitable attachments.

What is Electrical Discharge Machining (EDM) …

Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was an English physicist. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes.
