摘要:Abstract(#br)Laser Assisted Joining (LAJ) of Aluminum AA5053 sheets with Polyvinyl chloride (PVC) is investigated. The process was performed by means of a diode laser with a maximum power of 200 W. The materials did not show good chemical affinity. Thus, laser sculpturing was per...

摘要:Abstract(#br)Many industries need product identification; laser marking is suitable to produce any kind of symbol, data matrix or bar code on parts. Consequently, the most important requirement for marking acceptance is, doubtless, the mark readability. The present study deals on...

摘要:Abstract(#br)In the present work, different Artificial Neural Networks (ANN) architectures were developed and applied to predict the surface characteristics (roughness and depth) of laser milled pockets, performed on poly-methyl-methacrylate (PMMA) sheets. The experimental data w...
