Abstract: A method of controlling the position of a tilt/tilt style plasma arc torch relative to a workpiece for a bevel cutting operation is provided that includes: calculating a bevel pivot length, wherein the bevel pivot length is a function of a torch height; piercing the workpiece with the plasma arc torch; adjusting a position of the plasma arc torch by at least one linear offset value based on the bevel pivot length; rotating the plasma arc torch about its center of rotation to the desired cutting angle and maintaining a torch center point; and translating the plasma arc along its longitudinal axis to maintain a desired arc voltage between the plasma arc torch and the workpiece.
