the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

Abstract Deep drawing processes are strongly influenced by the blank holder forces, as well their local distribution. In current deep tools, this pressure distribution is dominated compliance of specific machine tool mounted on. Therefore, each must be manually polished to enable desired pressure. This regularly causes problems when transferring tools from one another, for example a try-out pre...

Abstract When the fine-blanking process is used, secondary grinding or processing can be omitted because shear surface of parts achieve almost zero fracture zone requirements. The primary objective to reduce depth and die roll width. This study used a 2.5-mm-thick central unit (CPU) thermal heat spreader as an example. Finite element analysis software was employed simulate optimize main eight p...

Abstract In the present research, the behavior of 304L austenitic stainless steel in the deep drawing process has been studied at the room temperature through experimental and finite element simulation method. Magnetic method calibrated by XRD was used to measure induced-martensite. Martensite volume fraction in the various portion of the deep drawn cup under optimum Blank Holder Force (BHF) a...

The earing profile of cylindrical cups is mainly dictated by the in-plane anisotropic behavior metal sheet. Nevertheless, for materials with a strong contact conditions between blank and blank-holder can also affect material flow due to non-uniform distribution forces. main objective this study numerically assess influence friction on cup using AA3104 aluminum alloy. anisotropy r -values leads ...

Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...
