This invention helps users of CNC machines, particularly for laser cutting or welding, to improve how they inspect and rework parts. A user can draw freehand lines directly on a touchscreen image of a workpiece to indicate where a new part should be added, and the system automatically refines these marks. One specific claim narrows the tool to a plasma cutting torch.
Why it matters: Filed before widespread adoption of advanced AI for image interpretation and CAD conversion. Modern machine learning models could now more accurately translate freehand marks into precise CNC instructions.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
