This article studies the limitations of laser machining of metals, and quantifies, through an experimental design method, the influence of operating parameters on productivity and on the quality of the machined surface.
In these field studies the limitations of geography precluded perfect matching of altitudes.
In such studies the limitations and advantages of IC and QRT-PCR must be considered.
As with all retrospective studies, the limitations of our study are inherent to the design, including the retrospective data collection.
