Abstract
Cutting is a process for obtaining parts that are widely used in the press tool industry. The calculation of cutting force is generally done by the simplified formula which only describes the shear force of the sheet (Fc = P.e.Rc). In this formula, we only see the perimeter of the part, the thickness and shear strength of the sheet.
In practice, other factors can influence this effort, such as, the clearance between the punch and the die, the speed of the cutting operation, the thickness of the sheet, the friction between the cut pieces and the die, etc. This work consists in making an experimental study, according to a complete experimental plan, to study the effect of some parameters, such as, the play between the punch and the matrix, the speed of cutting and the thickness of the sheet, on the cutting effort. This study is completed by a statistical analysis of the results and a modeling of the Fc effort according to the parameters studied.
