Abstract
An improved apparatus and method for laser assisted machining are provided, by utilizing a computer to develop interrelated heating and machining plans, from a variety of input data describing the material to be machined, the properties of lasers and pyrometers used for heating the material, and computer models of the machining arrangement, workpiece and final part to be produced. An iterative process continues until the machining and heating plans result in the cutting zone of the workpiece being maintained at a desired temperature with no obstruction in the line-of-sight of at least one laser and pyrometer throughout the machining process, while also maintaining the cutting tool at or below a desired maximum temperature.
