Part sorting is only the phased goal of the system. The highest goal of the system is to directly apply the data and files searched by the sorting method to all stages of product development through the method of small part sorting machine, so as to finally support CAD, NC programming, and process flow planning, and significantly accelerate the production speed of products. Information sorting can help customers search standard parts more quickly and conveniently, which is much better than manual search. Experience shows that the more easily a design engineer can find similar or homologous parts, the more likely he is to use the past design again and make design changes based on it, which can greatly accelerate the speed and efficiency of product research and development.
