Types of Chips in Machining

Types of Chips in Machining

Conventional machining operation always produces some chips. The nature of the chips depend on operation properties of the workpiece material cutting environment The cutting tool has to overcome the resistance of the work material to give it a desired shape. So cutting tool must be more harder, wear resistance than the w/p. The main reason […]

Electron Beam Machining (EBM) Principles

Electron Beam Machining (EBM) Principles

The source of energy in electron beam machining is high velocity electrons, which strikes the surface of the workpiece and generate heat. Electrons escapes from the hot surface and a voltage of 50 to 200 kV helps to accelerate them. These high energy electrons possess high energy density generally in the order of 10ˆ4 kW/mm² […]
