Experimental Investigation of Parameters Effect on Laser Forming Productiveness
In the present study the deformation behaviour of thin steel sheets processed by using laser forming has been investigated as well as the temperature distribution along the sheet thickness. A campaign of experimental tests has been carried out on stainless steel AISI 304 in order to evaluate the influence of the main process parameters, such as laser power, scanning speed and sheet thickness on the bending angle and temperature of upper and lower surfaces. In addition, in order to prevent oxidation, the optimal interval duration between two consecutive scans has been assessed. A productivity index has been also introduced in order to evaluate the effectiveness of different process parameters configuration.
