Proper usage of modelling in the design process should result in achieving the effective construction of the machine.However,the methodology of modelling should be adjusted to the specific application.This paper presents the algorithm of modelling the belt perforation process.Authors show the main aspects that should be taken into consideration during the design process of punching dies.Important correlations between construction,process and exploitation parameters are described along with the analysis methods.The main focus of the paper is put on the geometry of the piercing punch,which can significantly change perforation force,tool life and hole quality when it is modified.The paper also analyses the impact of punch velocity and temperature on the force necessary to pierce the material.Additionally,the methodology of determining the mechanical properties of the belt used for further modelling is discussed.
