What is Industry 4.0?

→ Industry 4.0 or the Fourth Industrial Revolution is based on the cyber-physical transformation of machining and manufacturing.
→ The current trend of automation and data exchange in manufacturing technologies is known as an Industry 4.0.
→ Sometimes it is also known as "I4.0" or "I4"
→ The name Industry 4.0 has arrived from the German government's initiative to promote manufacturing and a digital convergence between industry and computerization of manufacturing.
→ The basic principle of Industry 4.0 is that by connecting machines, workpieces, processes, businesses and many other things are creating intelligent networks along the entire value chain.
→ All these things are control each other autonomously.
