Laser Metal Forming (LMF) process is one of the prominent Rapid Prototyping (RP) process that can be used to develop functional and fully dense metal parts. This paper addresses process modeling, monitoring and control of a laser metal forming system currently under development at Laser Aided Manufacturing Processes (LAMP) laboratory at University of Missouri–Rolla. This LMF system is based on ...

Cold-rolled sheet metal that is often used in laser forming exhibits anisotropic properties, which are mostly caused by preferred orientations of grains developed during the severe plastic deformation such as cold rolling. In the present study, the textures of cold-rolled mild steel sheets are characterized and the influence of the plastic anisotropy on laser forming process is investigated. De...

In this paper, the three-dimensional bowl surface was obtained by reasonably planning radial heating path taking laser as heat source and stainless steel composite plate (06Cr19Ni10/1Cr17Mn6Ni5N/06Cr19Ni10) research object, forming process of studied. It found that target bending inside-outside symmetric scanning strategy (strategy d) had highest accuracy. The deformation increased with increas...

Cold rolled sheet metal often used in laser forming exhibits anisotropic properties, which are mostly caused by preferred orientations of grains developed during the severe plastic deformation. In present study, the textures of cold-rolled mild steel sheets are characterized and the influence of the plastic anisotropy on laser forming process is investigated. Deformation textures are measured i...

Laser assisted spin forming is used to process a galvanized Dual Phase steel with minimum damage to coating, microstructure and material properties. Effective increase in formability was achieved, but no evidence of recrystalization, neither drop in forming force was detected. The paper discusses the possible mechanism of formability improvement through the analysis by EBDS of laser assisted fo...

As part of a research project, new hybrid forming process for ultrathin three-dimensional glass elements was developed. In continuous chain, the three-part procedure enables large-area gravity-assisted bending thin glass, partial deep-drawing individual small structures using CO 2 laser radiation and cutting flexible inner outer contours. Using an experimental setup with scanning system, novel ...

Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...
