Analysis and optimization of surface quality of stainless steel miniature gears manufactured by CO2 laser cutting

Laser cutting is the popular unconventional manufacturing method widely used to cut various engineering materials. In this work CO2 laser cutting of AISI 314 satinless steel has been investigated. This paper focus on the investigation into the effect of laser cutting parameters like laser power, assist gas pressure, cutting speed and stand-off distance on surface roughness, hardness and kerf dimensions like kerf width, kerf ratio and kerf taper in CO2 laser cutting of AISI 314 stainless steel.

Super Alloy

This paper presented the experiments of Nd:YAG pulsed laser cutting of titanium alloy, super-alloy and stainless steel sheet, and investigated the influences of different laser cutting parameters on the surface quality factors focusing surface morphology. In comparison with air-, argon- and nitrogen-assisted laser cutting, argon-assisted laser cutting comes with unaffected surface quality and is suitable for laser cutting with subsequent welding requirement. With analyzing the interaction between pulses overlapping rate and energy, the results show that medium pulse overlapping rate and lower pulse rate helps to improve the surface roughness with pulsed laser cutting. And the results would be beneficial to find optimum cutting parameters for good separation surface.

Factors Of Influence

This paper presents the study of the influence of cutting parameters on surface quality in laser cutting of metallic materials. In this paper, it is shown which of the cutting parameters have the greatest influence on the quality of the processed surfaces by measuring various roughness parameters. After the experimental research was carried out a ranking of the factors of influence on the response functions was made, also graphs of dependency to various parameters of roughness were made.
