In order to solve the problems of machining unit, machine tool production process, production task overdue and low average utilization rate of equipment in machining workshop, the intelligent management and control technology of machining workshop was studied. The unit composition and production constraint analysis of machining unit workshop are described, and the system of data acquisition, storage, analysis and application of machining unit workshop is constructed. The key technologies of real-time data acquisition and storage, task scheduling and dynamic scheduling, intelligent management and control are analyzed. Combined with the actual composition and task situation of a workshop, the software development and implementation are carried out, and the application is deployed in the field. The application results show that the technology realizes the digital modeling and management of key production resources such as tasks and equipment in the machining workshop, improves the average utilization rate of machining equipment in the workshop and the on-time completion rate of tasks, effectively promotes the empowerment of intelligent management and control technology in the workshop, and promotes the digital transformation of enterprises.
