The production environment of aerospace industry is make-to-order. The life cycle of aircraft is more than 20 years. Aircraft parts should have higher precision and lightweight to achieve the requirements of safety, payload, and controllability. Machine parts are the important portion of aero-structures. Base on the strength, function, contour of machine parts, then assign to suitable machine center for machining. This study construct the shop floor control mechanism of aerospace machine shop which combine the concept of order release control, gateway control, queue level control, color code control, cycle time control, and apply the on-time dispatch and on-time completion as an indicator to monitor the performance of shop floor control. Thus, we can improve the weakness and increase the competitive advantages of machine shop in the global competitive aerospace market.
