| Abstract: | The question of compensating for the error of dimension due to spring back phenomenon when
forming metal sheet by SPIF method is being one of the challenges that the researchers of SPIF in the
world are interesting to and finding out to solve. This paper is only a recommendation that is based on the
macro analysis of a sheet metal forming model when machining by SPIF method for calculating a
reasonable recompensative feeding that almost all researchers have not interested: - Considering the metal sheet workpiece is elasto-plastic and the sphere tool tip is elastic the paper attempt to calculate for compensating the error of dimension due to elastic deforming of the tool tip. - The metal sheet is clamped by cantilever joint that has an evident sinking at the machining area that is calculated also to add to the compensating feeding value. The paper studies also the limited force for ensuring the elastic deforming at these working area of the sheet to eliminate all the unexpected plastic deforming of the sheet. With two small but especially new contributions, the question of elastic forming metal sheet of theoretical model advances nearly to the real situation. |
