“…Springback affects the final shape of the bent part and the resulting precision of the part [3][4][5][6][7]. The amount of springback after bending is affected by the radius of the bend, the material, the thickness of the material to be bent, the speed of the bend, and the temperature of the workpiece.…”

This paper concerns the design of the technology for the production of the part by bending and also the design of the forming tool for a small number of pieces of the produced part. The part in question was the oscillating tool blade to cut soft materials. The aim was to design economically advantageous technology to produce this blade without spot welding from two parts, preferably from one semi-finished product. A suitable material for the part and its new shape were designed. Calculations were made for the smallest recommended internal bending radius, the largest allowable bending radius, the smallest length of the bending arm, and the angle of springback after bending. The component’s shape and a suitable blank were determined. A low-cost bending tool was designed. Dynaform simulations were used to analyse deformation, material thickness after bending, and formability. Analyses showed that the designed bending manufacturing process is safe. The bending tool and then the cutting blade test pieces were produced to verify the tool’s functionality. The procedure for designing the manufacturing process and the forming tool presented in the paper can be applied in cases where it is necessary to design a suitable technology to produce a small number of parts by forming to achieve a minimum cost per piece of the manufactured part.
