Determination of forces affecting the cutter during shoe materials cutting

The subject of the investigation is the determination of forces effecting the cutter during shoe materials cutting with an analytical method. The research is being carried out to improve the accuracy of the design of tooling for a sewing semi-automatic machine. Determination of forces affecting the cutter during shoe materials cutting is done applying analytical method which is based on the representation of forces as functions of the relative deformation of material, numerical integration of these functions, and compilation of a program for determination of these forces. Using experimentally obtained data a technique is developed for the analysis of forces affecting the cutter during shoe materials cutting.
