    Meaning of Plasma Arc Machining (PAM): When a flowing gas is heated to a sufficiently high temperature of the order of 16,500°C to become partially ionised, it is known as ‘plasma’. In this process heat for machining is produced by convection from the high temperature plasma as well as due to direct electron bombardment.

  • INTRODUCTION TO CNC Plasma Arc Cutting

    plasma arc cutting in regard to stainless steel and aluminum. About a year later, the air plasma cutting process was developed, which used common air instead of nitrogen as the plasma gas. The addition of the available oxygen in the air created a higher level of heat energy, which in turn allowed for

    Plasma Arc Machining INTRODUCTION Plasma is the fourth stage of the material (solid, liquid, gas, plasma). At room temperature a gas usually consists of molecules which are dissociated into separate atoms at 2000°c. At 3000°c these atoms become ionized for the displacement of electrons from them, in this condition a gas is termed a plasma. In 1950s the cutting of materials by plasma arc ...
