Abstract : The mathematical aspect of the determination of the forces required in the punching of metal sheets is discussed. Certain parameters may be determined experimentally. Experiments were carried out on punching sheets 1-3 mm thick of steel No. 15, Steel No. 30, steel 1Kh18N10T, U8 steel, and L62 brass. The effect of various lubricants is noted. The proposed mathematical formula gives a satisfactory method of calculating the required strength of steel dies.
