IIT- Kharagpur develops novel Industry 4.0 tech for advanced manufacturing sector – education

IIT Kharagpur has developed a new Industry 4.0 technology for remotely controlled factory operations and real-time quality correction during industrial production in India’s advanced manufacturing sector, the Department of Science and Technology said on Friday. This innovation upgraded the industrial friction stir welding process to an Industry 4.0 multisensory system.

The innovative technology developed by Surjya K Pal, Professor in Charge of the Center of Excellence in Advanced Manufacturing Technology, IIT-Kharagpur, in partnership with TCS, will acquire real-time information about the welding process through multiple sensors and enable control online. welding quality by cloud-based communication with friction stir welding machine. “Welding is at the heart of any industrial operation. If we can improve weld quality in real time during batch production, we can reduce rejections in post-production sample checks, ”said Pal. Explaining the new technology, he said, “Our multi-sensor process involves various signal processing and machine learning techniques to predict the maximum tensile strength of the weld joint being manufactured.”

This technology is connected to a vast experimental knowledge base to conform to a standard system and the prediction of solder joint strength, he noted. “Any defect identified during the monitoring procedure is corrected in real time by sending modified parameters to the machine thus ensuring the standardized quality of the process,” he said. The concept of this technology may evolve further for real-time control of other industrial processes and such work will be carried out at the center with other industrial partners soon, Pal added.

“(The technology) has not only set the course for remotely controlled operations in the Indian industrial sector, it has also enabled real-time quality verification and correction during the production process.

“This will make it possible for industrial houses to achieve standardized quality objectives throughout the production process and reduce rejection, therefore reducing the cost of production,” the DST said in a statement.
