Solution Overview

Problem

Conventional modeling techniques for beam cutting applications, such as waterjet cutting, are limited in their ability to optimize tool paths and machine commands in real-time, requiring extensive manual trial and error, and are often not well-suited for rapid parameter changes or simultaneous review of multiple operating parameters, leading to inefficient use of resources and inferior results.

Innovation Solution

A software and hardware facility that automatically generates tool paths and machine commands for beam cutters, using statistical models based on empirical cutting data to predict cutting behaviors and optimize parameters such as cutting speed, jet lag, and taper, allowing for continuous adaptation and improvement with new data.

AI summary

A facility for automated modelling of the cutting process for a particular material to be cut by a beam cutting tool, such as a waterjet cutting system, from empirical data to predict aspects of the waterjet's effect on the workpiece across a range of material thicknesses, across a range of cutting geometries, and across a range of cutting quality levels, all of which may be broader than, and independent of the actual requirements for a target workpiece, is described.
