ANALYSIS OF THE METAL CONSUMPTION OF OPERATIONS PARTING AND HEATING BLANKS FROM ROLLED BAR ROUND SECTION
The paper presents results of a study the effects on metal consumption of the technological process of manufacturing of forgings on hot-crank press, precision diameter of rolled bar, precision cut pieces out of it, and their method of heating. Presents original dependences linking these parameters with the mass of stamped forgings. The criteria to assess the metal consumption of process hot die forming round forgings and the computer program that allows you to calculate these criteria. The most important feature of the method of calculating the parameters of blanks realized in the proposed software solution is the ability to determine their geometric parameters and quantification of metal loss in view of the included in software solution databases of geometrical parameters of rolled bar round section, as well as statistical databases on the accuracy of the cut pieces using various equipment and metal loss due to waste of metal when heated.
