Metal analyzing plasma CNC cutting machine and associated methods
First Claim
1. A metal analyzing plasma CNC cutting machine, comprising:
- a plasma cutting torch controllable to cut a workpiece with a plasma arc;
a lens positioned and configured to capture light from the plasma arc;
a spectrometer coupled to receive the captured light from the lens through an optical fiber path and adapted to determine spectral data of the light;
at least one computer having a processor and memory storing spectral analysis software that includes machine readable instructions executable by the processor to analyze the spectral data and generate a determined composition indicative of a composition of the workpiece,the spectral analysis software further comprising machine readable instructions stored in the memory and executable by the processor to compare the determined composition to an expected composition of the workpiece and to generate an alert on a user interface of the at least one computer when the determined composition does not match the expected composition.

Abstract
A plasma computer numerically controlled (CNC) cutting machine is controlled by a computer such as a personal computer capable running an operating system and software programs. In an embodiment, the computer executes a CNC program to control movement of a plasma torch to cut parts from a workpiece while a spectrometer determines an emissions spectra of light emitted as the torch cuts the workpiece. The spectrometer cooperates with software running on a computer to analyze the metal as it is being cut by the CNC cutting machine and determine a composition. In embodiments, the composition is compared to an expected composition and saved in a database with identifying information; in a particular embodiment the database is queried to provide identifying information of metal having similar composition to the workpiece.
