  • Difference Between PAM and IBM - Plasma Arc Machining and Ion ...

    May 07, 2020 · Working principle of Plasma Arc Machining PAM process uses ionized plasma to transfer heat. The plasma is obtained by forcing gas through an electric arc generated between cathode and andode. The high temperature plasma jet melts the metal and remove material from the workpiece.

  • Plasma Arc Machining – ADTW Learn

    Apr 21, 2015 · INTRODUCTION  The plasma arc machining process was introduced to the industries in 1964 as a method of bringing better control to the arc welding process in lower current ranges.  Plasma-arc machining (PAM) employs a high-velocity jet of high- temperature gas to melt and displace material in its path.  Today, plasma retains the original advantages it brought to industry by providing an advanced level of control and accuracy.

  • What are the Advantages and Limitations of Plasma Arc Machining?

    There are two types of Plasma Arc Machining (PAM) Systems such as Transferred Arc PAM system and Non-Transferred Arc PAM system. In Transferred Arc PAM system, Plasma arc is transferred between electrode and workpiece.
