For example, the processing speed of a circular sawing machine is high, and when a plurality of blank workpieces are continuously sawn, the storage sliding table is fully arranged, and then the operation is stopped. When the light sensing signal senses that the last row of workpieces on the storage sliding table are not available, the time delay is delayed until the workpieces on the storage sliding table are close to the absence of the workpieces, and then the circular sawing machine is started to work. The time delay control time can be set by a computer control platform on the circular sawing machine. The intermittent time control of the numerical control lathe is the same as the delay control principle of the circular sawing machine.
