Dual light source machining method and system
First Claim
1. A method of machining a workpiece, comprising the steps of:
- removing a first portion of the workpiece by directing a first light beam to the workpiece wherein the first light beam has an intensity sufficient to ablate material from the workpiece; and
heating a second portion of the workpiece to a ductile state by directing a second light beam to the workpiece.

Abstract
Disclosed herein is a system useful for machining a workpiece, and having a first light source to generate a first beam for application to a first portion of the workpiece and ablation thereof, a second light source to generate a second beam for application to a second portion of the workpiece and heating thereof, and a positioning apparatus to direct the first and second beams to the first and second portions of the workpiece, respectively. The first light source may include a machining laser, and the second light source include a softening laser. A method of machining the workpiece includes the steps of removing a first portion of the workpiece by directing the first beam to the workpiece wherein the first beam has an intensity sufficient to ablate material from the workpiece, and heating a second portion of the workpiece to a ductile state by directing the second beam to the workpiece.
