Study On Computer Numerical Control System Of Laser Cutting

People pay more and more attention on laser cutting processing because of its advantage, and all sorts of laser processing system are developed on the different fields of industry. Now the machines of laser cutting processing made in China drop behind the ones made in western country on laser power controlling, laser focus position controlling and the quality of processing. And it's expensive to buy CNC system made in western country for the minor enterprise. So we research and develop the CNC system of laser cutting processing.This paper includes six parts: (1) Preamble, (2) Introducing the machine of laser processing, (3) Research of laser power controlling, (4) Research of laser focus position controlling, (5) Design of G-Code compiling environment, (6) summarization.Introducing the status quo and foreground of the CNC system of laser cutting processing.Introducing the machine of GS-2000 CO2 Laser and the relevant fixture of processing.Discussing the necessary of laser power control in cutting processing.Giving out a method to realize laser power controlling.Proving the feasibility to realize laser power controlling on the controllable silicon laser power through the cutting experiment.Discussing the principle and capability target of laser focus position controlling.Designing G-Code compiling environment.Giving a detailed design report.Summarizing total research work.
