Abstract

Smart manufacturing process was developed to manufacture the demonstrator access door panel. The process integrated three basic methods, process simulation, process monitoring, and process control. For the first step, we simulated and predicted how the resin impregnated through the perform. And taking this result into consideration, we fixed the process parameters. In manufacturing, the dielectric film sensor was placed on the surface of the mold cavity to evaluate the resin flow. Dielectric property of the sensor changed as the resin impregnated. Dielectric sensor system is linked to the process control system. A personal computer of the control system acquired the process data from sensor system and controlled the pressure of the injection point. The three-dimensional door panel, 700mm width, with Fiber Bragg Grating (FBG) sensors embedded, without any dry-spot existing, was manufactured by this method. Effectiveness and advancement of smart manufacturing process was confirmed.
