Alternative Method of Forming Hard To Form Metal by using LASER: A Review

This paper gives a review for a new technique to give shape to metal by laser source is presented. Typically metal forming by Laser is contactless method in which laser beam is used as energy source and by inducing temperature induced stress in material, we can form material in various shapes. The main benefit of laser forming lies in its capability to form low ductility metal and with high accuracy of forming which normally not possible in conventional forming process which uses mechanical tool and die. In this paper various experimental result and observation of laser forming technique is presented so that one can easily analyze the laser forming technique and its capability and limitations. The important parameters which affect process results are laser beam diameter, sheet thickness, laser input power, scan velocity and material properties. By suitably choosing above parameters two dimensional and three dimensional geometry had been formed from
