Mechanical manufacturing automation: This is the result of the combination of mechanization, electrification and automatic control. The object of processing is discrete workpiece. The early mechanical manufacturing automation is the use of single machine automation of mechanical or electrical components or simple automatic production lines. Since the 1960s, due to the application of electronic computers, there have been CNC machine tools, machining centers, robots, computer-aided design, computer-aided manufacturing, automated warehouses, etc. A flexible manufacturing system (FMS) suitable for multi-variety and small-batch production has been developed. The automatic workshop based on flexible manufacturing system, together with information management and production management automation, has emerged the factory automation using computer integrated manufacturing system (CIMS).
