<p>The digital twin represents a significant direction for the digital transformation of factories. Traditional process manufacturing is characterized by limited real-time interaction and insufficient transparency, hindering effective monitoring of production data and delaying the timely response to production incidents. These limitations make it increasingly unsuitable for the demands of the digital age. This paper proposes a digital twin system for process manufacturing and explains the interaction process of the digital twin system from the perspective of data circulation. Without introducing additional dimensions, the five-dimensional model is materialized into a system composition and operation logic for process-oriented manufacturing. First, it introduces the theoretical framework of the five-dimensional model of digital twin system; second, the development methods and key enabling technologies of the digital twin system are summarized; finally, it takes the production equipment line as the research object to verify the effectiveness of the proposed method. Experimental results indicate that this system possesses functions such as remote monitoring, data analysis, remote control, process tracing, and VR interaction. This research establishes the groundwork for advancing the remote and autonomous operation of process manufacturing.</p>
