Abstract

This lecture covers the thermal processes of CO2 laser cutting, the laser qualities most important for cutting, and the mechanics of the cutting process. In addition, a comparative analysis of alternative thermal cutting processes, and alternative beam manipulation systems, are reviewed including new developments in Nd: YAG laser cutting systems with fiber optic delivery coupled to a robot. Laser cutting advantages are reviewed and actual applications of in-production laser cutting systems are discussed. The major specific subjects covered include the following: History and types of CO2 lasers for cutting; Description of laser cutting processes and related parameters; A comparative analysis of laser and other thermal cutting processes; Analysis of laser beam delivery and motion systems benefits associated with Laser Cutting Systems; New developments in Nd: YAG robotic cutting systems with fiber optic beam delivery; and, Actual applications of in-production Laser Cutting Systems.
