Laser forming is expected to be able to form a desired shape out of sheet metal or sheet plastic without the use of a die or mold. Laser forming plastically deforms the material by generating local heat stresses, and enables low cost rapid prototype or small lot production, since it eliminates the need for dies and molds. Although there are many studies on laser forming, there are relatively few studies on forming curved surfaces. The objective of this paper is to develop a method for forming curved surfaces out of sheet material utilizing laser irradiation. To achieve this objective, a method to determine the scanning paths and the scanning condition for making curved surfaces by laser irradiation is proposed. The scanning paths are determined as the maximum and minimum curvature lines, and the scanning condition, which is a function of the scanning speed, is derived from basic experiment data. Since the maximum and minimum curvature lines are orthogonal, they do not influence each other during forming.

Dies and molds are generally used for press forming and injection molding. However, they are expensive and their production is time consuming, so they are not suitable for prototyping or low-volume production. Laser forming is an effective tool for prototyping and low-volume production because it enables one to form sheet material without dies or molds. Laser forming is the deformation process caused by the thermal stress generated in the sheet by laser irradiation. In this paper, a Laser Forming System is proposed for determining laser irradiation conditions for forming a required shape.

Laser forming is a technology that produces plastic deformations in sheet materials by generating local heat stress. It is useful for prototype or small-quantity production because it does not require dies or molds. Although many studies on laser forming have been done, few have been on forming curved shapes. This paper deals with a method for generating the scanning paths and determining the scanning conditions for laser forming of a curved shape. The scanning paths are derived as the maximum and minimum curvature lines. Since the two curvature lines are orthogonal, they don’t affect each other in forming. The scanning speed is decided by an approximation equation derived from experiment and FEM analysis according to the angle of the bend at the irradiation point. The effectiveness of the scanning paths and the scanning speed determined by the proposed method are confirmed through experiments.
