Abstract

Results of a study of the effects of process parameters on the quality achieved during laser cutting of alumina are presented. The effects of the interaction time, irradiance and assist gas pressure on the quality output variables such as striation angle, striation wavelength and the distance of clearly defined striations are studied. A physical interpretation of the correlation matrix and regression models develop is given. For the range of operation condition tested, it was observed that the inclination of the striation is most affected by interaction time, with assist gas pressure having a secondary effect and irradiance playing a minor role. Striation wavelength and upper and lower striation lengths are most influenced by interaction time and irradiance, both causing longer wavelengths. © 2007 Springer-Verlag London Limited.
