Abstract—The purpose of this research is to develop an automatic design system for automobile lamp inspection jig based on know-how. The inspection jig consists of a sub-gauge, which is a measuring block, and inspects the height and outer peripheral shape of the design surface. The sub-gauge usually comprises two surfaces: a surface with a step difference of 0 mm from the design surface and a surface with a gap of 2 mm from the design surface. In this report, the former is called the step surface and the latter is known as the gap surface. In this research, we utilize the design knowledge and know-how acquired from the interview with an expert to automate the inspection jig design. The step surface is created using straight lines obtained from the intersection of the design surface and planes arranged at equal intervals. The gap surface is created from the offset surface of the side adjacent to the design surface. The sub-gauge is constructed as a solid with these two faces. Finally, the presence of an interference between the product and sub-gauge is determined and removed. The proposed system executes the processes, including step creation, gap creation, sub gauge creation, and interference cancellation using the SolidWorks API.
