Force and pressure function formulation for direct cold extrusion of aluminum alloy Al 1350 using regression method

Purpose. Establishing methodology in order to determine mathematically both extrusion force and pressure functions for Aluminum alloy AL 1350 using the regression method of experimental data. Methodology. Several variables (diameter cavity pressing D, degree extrusion, angle punch head cone 2, ratio semi-finished sizes Rs) were included when considered. Findings. Diameter strain found play a significant role predicting associated with process. Mathematical formulas obtained method. Amethodology has been developed mathematical determination pressure. Originality. Force direct cold process are mainly required design dies. However, existence such data literature is insufficient implement aluminum alloys as well other materials. Results study consider main factors influencing differences types alloys. Practical value. The by provide tool calculating values
