Abstract: A method of operating a plasma arc torch system includes placing a work piece to be cut on a table of the plasma arc torch system, wherein at least a portion of the work piece has a planer surface facing away from the table. A plasma arc torch is positioned adjacent the planer surface of the work piece using a positioning apparatus, wherein the positioning apparatus has at least five degrees of freedom about which it can move the plasma arc torch relative the work piece for cutting the work piece on the table. The method further includes angling the torch relative the planer surface of the work piece such that the torch is held at an angle of between about 1 and about 4 degrees from perpendicular with the planer surface to back burn a produced kerf such that a kerf edge is perpendicular relative the planer surface of the work piece. Additionally, the planer surface of the work piece is calculated by contacting the work piece with the torch at least three times.
