This research presents the design and performance test of three roll metal bending machine (shaft design). The main purposes of this research are to construct a three roll metal bending machine and to do the performance tests. The aim of this project is to develop a portable metal bending machine to bend sheet into curves and the other curvature shapes. In this research, shaft diameter is calculated by using ASME code equation. Mild steel shaft is selected for design to obtain high strength. The estimated diameter of rotating shaft is 31.75mm and main shaft is 25.4mm. Pillow block bearing UCP205 is selected. The estimated value of Factor of Safety is 3.32. Therefore, the determination of research design is totally safe. As a lot of time is consumed when metal bending is made by hand, so using bending machine will save the waste time. The size of machine is small and it is convenient for portable work. No skill worker is required to operate the machine.
