In the present work, the use of multi-passes laser scan techniques in cutting operation of CFRP thin sheet is investigated using a Q-switched diode pumped Nd:YAG laser source. First, in order to obtain the process effectiveness, engraving tests were performed changing the process parameters, verifying the groove depth and the groove width. From the results, the optimum work parameters were individuate as the ones that produce the maximum depth with the same scansion numbers. These parameters were used in the final cutting tests considering the number of repetitions necessary to completely cut the laminate and the effective cutting speed. Moreover, optical microscopy analysis were done in order to evaluate the kerf geometry and the HAZ extension.

Abstract
In the present work, the use of multi-passes laser scan techniques in cutting operation of CFRP thin sheet is investigated using a Q-switched diode pumped Nd:YAG laser source. First, in order to obtain the process effectiveness, engraving tests were performed changing the process parameters, verifying the groove depth and the groove width. From the results, the optimum work parameters were individuate as the ones that produce the maximum depth with the same scansion numbers. These parameters were used in the final cutting tests considering the number of repetitions necessary to completely cut the laminate and the effective cutting speed. Moreover, optical microscopy analysis were done in order to evaluate the kerf geometry and the HAZ extension.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
