PRODUCTION METHOD AND PRODUCTION LINE FOR WORKPIECE MATERIAL-FLOW SYSTEM TO IMPLEMENT TOOL MATERIAL-FLOW EXCHANGE

A production method and production line for a workpiece material-flow system to implement tool material-flow exchange. The method comprises: mounting a load into a workpiece material-flow pallet (1); inputting a physical attribute of the load and information of the workpiece material-flow pallet (1) into a production line control system; a workpiece material-flow system transferring the workpiece material-flow pallet (1) to a target computer numerical control (CNC) machine tool; an exchange mechanism feeding the load into the CNC machine tool; and the CNC machine tool receiving the load and performing a tool grabbing action/workpiece machining action. The workpiece material-flow pallet (1) supports a tool carrier (2) and/or a workpiece and transfers a tool and/or the workpiece, and a CNC machine tool spindle is used to grab the tool, so as to perform tool changing, tool magazine supplementation or direct machining, so that workpieces and tools can share one material-flow system and the workpieces and the tool
