Calculation and design for a 3-roller sheet bending machine for small production operationswere based on theoretical studies and real manufacturing practices. Dimension parameters of the machine were calculated based on materials used in manufacturing process and machinery parts. The bending machine can manufacture machinery parts with different diameters and heights by using some types of steel with thickness from 1 to 4 mm, length from 400 to 2000 mm and width from 50 to 800 mm. Based on design drawing, a 3-roller sheet bending machine was manufactured and used for manufacturing machinery parts.
