Design and Development of PLC Based Shear Knife for Automatic Sheet Metal Cutting

This paper introduces an advanced automatic sheet metal cutting system that seamlessly integrates Programmable Logic Controller (PLC) and Human-Machine Interface (HMI) technologies, revolutionizing manufacturing processes. The system's primary objectives include enhancing operational efficiency, accuracy, and safety standards. By utilizing precision sensors and responsive actuators, the system performs intricate metal cutting operations according to customer specifications. The HMI touch screen serves as the interface through which operators interact with the system, while the PLC processes data and dispatches instructions to the pneumatic cylinder, orchestrating the cutting operations. The HMI interface empowers operators with real-time oversight and control over the cutting process, enabling prompt adjustments based on feedback. Safety measures such as emergency stop buttons and interlocks further ensure operator well-being and prevent accidents. The integration of PLC and HMI technologies significantly reduces human errors, boosting productivity and ensuring precise cutting results. This innovation redefines industrial automation benchmarks, offering industries an efficient, accurate, and secure solution for high-speed cutting processes.
