CPS-Based Smart Manufacturing: Integration of Sawing and Punching for Aluminum Profile

The work aims to put forward an intelligent manufacturing based on CPS (Cyber- Physical Systems), in order to realize the goal of digitization, networking, high efficiency and fewer people in the integrated sawing and punching production of aluminum profile, improve product quality, and promote the intelligent transformation and upgrading of enterprises. In this paper, firstly by building a smart industry with three-tier architecture: physical devices, network and applications, we proposed a solution based on CPS for aluminum profile production. This solution allows the smart factory to be integrated with other systems, and industrial data information coming from different kinds of industrial control system to be collected together, so as to integrate, exchange and share multi-source heterogeneous data in a closed-loop system. Then, aiming at the sawing machine, we analyze the quality of production process based on data association rule, then we find and control the key factors which cause quality fluctuation, so as to improve the quality in the production process of sawing machine. Then, we use OEE (Overall Equipment Effectiveness) method to calculate the production efficiency and do the experiment. the experimental results are used to verify whether the efficiency of the proposed system and the practicability satisfy the requirements. Finally, the production line capacity efficiency increased by 48.5% and product qualification rate was 99%
