The Effects of Plasma Arc Cutting Process Parameters

Plasma arc cutting is the process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma.The basic plasma arc cutting process involves creating an electrical channel of ionized gas i.e.plasma from the plasma cutter itself,through the work pieceThe Basics of Plasma Cutting - ESABPlasma Cutting Process.Plasma cutting is the fastest cutting process on carbon steel,aluminum,or stainless steel.Plasma cutting can be combined with waterjet or oxy fuel on the same part.Plasma cutting can be use for precision cutting on gauge material up to 6 thick stainless.REGRESSION ANALYSIS OF THE PLASMA ARC CUTTINGThe effect of oxy-fuel cutting,plasma cutting and laser cutting on the fatigue behavior of cut straight edges performed on four different steels was analyzed in [5].Grey relation analysis was used for optimization of process parameters in plasma arc cutting of EN 31 steel based on material removal rate and multiple roughness characteristics [6].
