The study deals with an automatic measurement system for thickness of free curved plates. The system consists of a laser thickness gauge composed of faced two laser displacement sensors and an industrial robot as workpiece positioning device to achieve appropriate measuring posture. The system measures the workpiece shape, and the thickness based on the acquired shape data. In this paper, each error factors of the system are verified, and thickness measurement error was estimated from the verified error factors. From the experimental result, it was confirmed that it is possible to measure the thickness within the estimated error.
