The intention of this research is to make analyze of deep drawing Cr-Ni stainless steel process. The research is related to forces that appear in machine tool during the process and also to material stress and its behaviour. The results are taken from two sources and their comparison is made. The first source of results are experiments made on hydraulic press, and the other source are results o...

In general, deep drawing products have various cross-section shapes such as cylindrical, rectangular and nonaxisymmetric shapes. The application of the surface area calculation to non-axisymmetric deep drawing process has not been published yet. In this research, a surface area calculation for non-axisymmetric deep drawing products with elliptical shape was constructed for a design of blank sha...

Abstract First of all, a negative clearance deep drawing scheme is proposed for micromotor shell product with specular surface quality. The condition used to make the material bear strong extrusion and plastic deformation in process so that mirror realized, roughness Ra below 0.2 mm. Next, three-step forming developed, parameters each step are designed optimized. quality evaluated by finite ele...
