WORKPIECE EDGE DETECTION USING PLASMA ARC CUTTING SYSTEM

摘要

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.

1. A computer program product, tangibly embodied in a non-transitory, computer-readable storage device, for identifying an edge of a workpiece, the computer program product including instructions operable to cause an automated cutting system to:
receive trace data for a test path to be traced over the workpiece; flow a gas from a torch of the automated cutting system; control the torch in accordance with the trace data to trace the test path over the workpiece; obtain a set of back pressure values by monitoring a back pressure of the gas during the tracing of the path; map the set of back pressure values to a set of coordinates; and identify an edge of the workpiece using the set of back pressure values and the set of coordinates.
