To promote the "Connected Industries" project by utilizing the Internet of Things (IoT) and artificial intelligence (AI) systems, sensing of various deformation process information during processing is required to develop advanced metal forming technology in the deformation processing field. In recent years, sensors and sensing systems based on new sensing principles have been studied and developed. In this paper, a state-of-the-art typical sensor and its system applicable to metal forming processes are described, in which it is difficult to visualize the processing conditions and material deformation state inside dies. Also, the issues and initiatives for intelligent metal forming processes are introduced. In addition, we discuss the advantages and necessity of advanced in-process intelligent control metal processing technology with sensors embedded into a practical forming machine.
