Under the drive of Industry 4.0, the integration of various technologies has become one of the challenges in the transformation towards smart manufacturing. Smart manufacturing is primarily based on digitization, constructing intelligent processes for production, equipment, and management that connect design, production, and service. This approach aims to reduce costs, improve manufacturing efficiency, optimize quality and experience, and strengthen industrial competitiveness. Next, we will introduce these innovative technologies from smart manufacturing, laser applications, and precision machining.
