The experimental study regarding the laser bending of sheet metal parts of various shapes at different irradiation conditions is reported. The present work is carried out using Nd: YAG laser (average power of 200 W, pulse duration of 0.1 -10 ms). Plates made of alloyed steel of various grades and having thickness from 0.3 to 1.1 mm were used as samples. Formation of laser beam path on the odd-shaped parts was executed by the programmable 6-axis robot Motoman SSF-2000.

“…Since its first reports, laser forming has been used to bend sheets of common metals, such as stainless steel [67][68][69] and aluminum [70][71][72], out of plane without mechanical inputs [36,37,67]. As the understanding of the process developed, more varied substrates were explored such as titanium, [27,73] and copper alloys [74,75], hoping to develop new ways to form 3D structures for aerospace and electrical applications.…”

Lasers can be used to bend 2D metal sheets into complex 3D objects in a process called ‘laser forming.’ Laser forming bends metal sheets by locally heating the sheets to generate plastic strains and is an established metal bending technology in the shipbuilding industry. Recent studies have investigated the laser forming of thin metal parts as a complementary rapid prototyping technology to metal 3D printing. This review discusses the laser forming process, beginning with the mechanisms before covering various design considerations. Laser forming for the rapid manufacturing of metal parts is then reviewed, including the recent advances in process planning, before highlighting promising future research directions.

“…Al alloy sheet metals can be laser bent efficiently also by using laser sources with low specific power [1]. Depending on the process conditions, stresses may arise in the bent part and deformation may occur due to secondary working [2]. Recently the feasibility of laser forming of aluminum foam sandwich (AFS) panels [3] and aluminum alloy sponges (i.e.…”

Laser forming ofopen-cell aluminum foams can be modeled by means of 3D thermo-mechanical models but the correct evaluation of the alloy material properties is a key-factor for obtaining good predictions. In order to increase the model predictability from a quantitative point of view, further information about the material behavior under laser exposure is necessary. In this study the effect of the temperature on the mechanical properties of a commercial aluminum sponge has been evaluated in terms of yielding stress and tangent modulus. Experimental tests have been performed by compression and used to infer mechanical properties by means of a 3D FE model. The same approach has been used also to evaluate the effect of a heat treatment of the sponge on the material behavior during forming. In conclusion numerical simulation of laser heating has been used to show the effect of the laser-material interaction on the final homogeneity of processed foams.
