Design and fabrication of a low-cost pneumatic sheet metal cutting and bending machine

Abstract

This project focuses on the design and fabrication of a low-cost pneumatic sheet metal cutting and bending machine suitable for small and medium-scale industries. The machine employs a double-acting pneumatic cylinder controlled by a 220V solenoid valve to automate cutting and bending operations on low to medium thickness sheet metals. The pneumatic system, operating at 6–8 bar pressure, provides rapid, reliable, and precise force application, reducing manual labor and improving productivity. The machine’s compact and portable design allows easy handling and maintenance, while interchangeable punches and dies enable versatility in sheet metal processing. This approach offers an economical alternative to hydraulic systems, emphasizing simplicity, efficiency, and automation to meet industrial demands for quality and speed.
