SME MR97-186

Striation formation on laser made cuts results in poorer surface finish and post-cut operation often becomes necessary as a result. Proper process planning reduces, but not eliminate striations, and on-set or characteristic changes of striations in process has routinely been observed. On the basis of high speed filming and pyrometer investigations, experiments were carried out using a photodiode based sensing system. Signals are analyzed using both parametric and spectral methods and results show agreement with measured striation data. The experimental results also agree with previous theoretical calculations.
