With the advancement of the Industry 4.0 wave, artificial intelligence (AI) technology is profoundly reshaping the entire industrial chain of the machining industry. As "customized solutions" in the industrial field, non-standard mechanical equipment, characterized by complex design and high production flexibility requirements, is deeply coupled with AI technology. In 2023, the global industrial AI market size exceeded $40 billion, with the non-standard equipment sector accounting for 27%, marking that AI technology has evolved from an auxiliary tool to a core driving force in this industry. This article systematically explores the full-process application of AI in non-standard mechanical equipment, from product design to operation and maintenance services, focusing on analyzing technological breakthroughs and industrial value in core aspects such as intelligent design, intelligent process planning, intelligent machining and quality control, intelligent supply chain optimization, warehouse logistics revolution, intelligent assembly and debugging, predictive maintenance, and the integration of intelligence and the Internet of Things.
