US 2016/0354856 A1 · WORKPIECE EDGE DETECTION USING PLASMA ARC CUTTING SYSTEM

Abstract

Systems and methods can be provided to use an automated cutting system to identify an edge or multiple edges of a workpiece. An automated cutting system receives trace data for a test path to be traced over a workpiece. The automated cutting system includes a torch from which gas is flowed. The torch is controlled in accordance with the trace data to trace the test path over the workpiece. A set of back pressure values are obtained by monitoring a back pressure of the gas during the tracing of the path. The back pressure values are mapped to a set of coordinates. An edge of the workpiece is identified using the set of back pressure values and the set of coordinates.
