In this work, a 100 W fibre laser working in CW or modulated regime was used to cut Ti 6Al 4V alloy sheets 1 mm in thickness. The work is aimed at studying the effects of the main process parameters on the kerf geometry and HAZ. The tests were conducted in two steps: first, the maximum cutting speed were determined in both CW and pulsed regime changing the mean power and pulse duration. Then, for the same process conditions, tests were done decreasing the cutting speed from the maximum to the 80% of this. Finally, the effects of the process parameters on the Kerf geometry and HAZ have been analysed.

Abstract
In this work, a 100 W fibre laser working in CW or modulated regime was used to cut Ti 6Al 4V alloy sheets 1 mm in thickness. The work is aimed at studying the effects of the main process parameters on the kerf geometry and HAZ. The tests were conducted in two steps: first, the maximum cutting speed were determined in both CW and pulsed regime changing the mean power and pulse duration. Then, for the same process conditions, tests were done decreasing the cutting speed from the maximum to the 80% of this. Finally, the effects of the process parameters on the Kerf geometry and HAZ have been analysed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
