随着新一代信息技术、通信技术、物联网技术的高速发展，制造业向数字化、网

With the rapid development of a new generation of information technology, communication technology, and Internet of Things technology, the manufacturing industry is leaping towards digitalization, networking, and intelligence [1]. The traditional large-volume and large-scale manufacturing model has gradually been eliminated, and the replacement of emerging products is becoming more frequent. New market demands are facing severe challenges such as diversification and personalization, small batches and multiple varieties, and short-term quick response [2]. In the full life cycle of the product, as a transition from the design stage to the manufacturing stage of a mechanical product, processing process planning is an important basic work of modern manufacturing. It realizes the conversion of product design information to manufacturing information and connects product design and product manufacturing. The design process is highly empirical and changes with the changes in the manufacturing environment. The design results directly affect product quality, production cycle, production organization efficiency, manufacturing resource allocation, environmental benefits and other aspects [3-5]. Under the current background of structural adjustment and intelligent transformation and upgrading of the manufacturing industry, the mismatch between the level of process planning and design and the ability of intelligent manufacturing has become one of the shortcomings restricting the development of enterprises and is a technical difficulty that needs to be solved urgently.

With the rapid development of a new generation of information technology, communication technology and Internet of Things technology, the manufacturing industry has leapt to digitalization, networking and intelligence. The traditional large-scale manufacturing model has been gradually eliminated, the emerging products are being updated more and more frequently, the new market demand is facing a variety of personalized, small-volume multi-variety, short-cycle rapid response and other severe tests. In the whole life cycle of the product, as the transition of mechanical products from the design stage to the manufacturing stage, processing process planning is an important basic work of modern manufacturing industry, it realizes the transformation of product design information to manufacturing information, is the link between product design and product manufacturing, its design process is empirical and changes with the change of manufacturing environment, the design results directly affect product quality, production cycle, production organization efficiency, manufacturing resource allocation, environmental benefits and other aspects. Under the background of the current structural adjustment and intelligent transformation and upgrading of manufacturing industry, the mismatch between the level of process planning and design and the ability of intelligent manufacturing has become one of the short boards restricting the development of enterprises, and it is an urgent technical difficulty to solve.

With the rapid development of the new generation of information technology, communication technology and Internet of things technology, the manufacturing industry is leaping forward in the direction of digitization, networking and intelligence [1]. The traditional mass production mode has been gradually eliminated, and the new products are updated more and more frequently. The new market demand is facing severe challenges such as diversification and personalization, small batch and multi variety, short cycle and fast response [2].
