The program calculates the drawing diagram of Carbon and Stainless Steel wires, Bronze, Aluminium and Zinc wires. For Aluminium and Bronze, we considered the analysis more popular and with the higher tensile strength. For Zinc we considered the material with 99% of base material. For Other materials it is possible to enter the Inlet and Outlet Tensile. In this case the program calculated the intermediate values with a linear interpolation. It calculates the diameter sequence and the relative reduction, the material tensile strength, the needing drawing force, the speed and the power for each pass. It is possible to work with constant or with decreasing reductions, to set the reduction of the last block and, in the case of external skinpass, to set the value of it. It suggests the needing number of dies calculated in function of the material tensile strength. It suggests the theoretical angle(2alfa) of the working cone of the die calculated in function of the reduction and of the tensile strength of the material. It foresees the final tensile strength of the material basing its calculation on practical values obtained from real experience. It calculates also the productivity of the machine with possibility to set the efficiency of it. It calculates the draw per pass using the advanced formulas of the Homogeneous Work, as inside specified. It calculates the needing motor power per pass and the total power of the diagram. The program works with International Unit Measure (SI) or with United States Customary Units (USC).
