Bulk deformation and sheet metal forming are two common manufacturing processes used to shape metals into desired forms. While both methods involve the deformation of metal, they differ in terms of the starting material, the types of products produced, and the specific techniques employed.Journal of Materials Processing Technology 140 (2003) 555–561 A comparative estimation of the forming load in the deep drawing process F. Fereshteh-Saniee∗ , M.H. Montazeran Mechanical Engineering Department, Faculty of Engineering, Bu-Ali Sina University, Hamedan 65176, Iran Abstract The deep drawing process is one of the important sheet-metal forming processes. Sheet-bulk metal forming (SBMF) is a promising process for manufacturing complex sheet components with functional elements. In this study, the entire forming process for a typical thin-walled component with external gearing is investigated, including sheet forming and bulk forming processes. Deep drawn cups are prepared during sheet forming; subsequently, .
In addition to the technical aspects of metal forming, the course also covers the defects that can occur during metal forming processes and their potential solutions. This knowledge is critical in designing and implementing manufacturing processes that meet the growing demand for precision products and cost-effective production methods.•Hydro-forming – cheap tooling, no net thinning, slow, high formability Material stretched into shape •Stretch forming – very cheap tooling, net thinning, slow, low formability •Super-plastic forming – cheap tooling, net thinning, expensive sheet metal, slow, very high formability Technology – a brief review Forming Speed 20 .
In bulk- or sheet-metal-forming processes, the effect of friction on the manufacturing of automotive parts has become increasingly important to avoid inferior formability and shape changes as new lightweight alloys and high-strength steels are introduced. .

The sheet-bulk metal forming (SBMF) process class can meet these requirements by applying bulk forming to semi-finished sheet metal products. This is often done in combination with sheet metal forming processes, which expand the range of components that can be produced [1]. The combination of bulk and sheet metal forming leads to challenges .

ºõ³ . Monitoring systems in sheet metal forming cannot rely on direct measurements of the physical condition of interest because the space between the die component and the material is inaccessible. In that context, the application of bulk forming operations on sheet metal semi-finished products - also referred to as sheet-bulk metal forming (SBMF) - is a suitable approach to meet these challenges. One of the most relevant industrial forming processes is the cold extrusion, which enables a high material and energy efficiency. The deep drawing process is one of the important sheet-metal forming processes. Using this operation, many parts are manufactured in various industries. In this paper, different methods of analysis such as analytical, numerical and experimental techniques are employed to estimate the required drawing force for a typical component.
Fig. 1.3.1: Classification of metal forming processes Typically, metal forming processes can be classified into two broad groups. One is bulk forming and the other is sheet metal forming. Bulk deformation refers to the use of raw materials for forming which have low surface area to volume ratio. Rolling, forging, extrusion and drawing are bulk . Sheet-bulk metal forming processes are forming processes in which often conventional sheet and bulk forming operations are combined. These processes are applied to sheets or plates. . For a sophisticated calculation of the permitted tool load to lay out the die and the prestressing system FEM is required.
It is a method of producing contours in sheet metal. Thinning and strain hardening is inherent in the process. Stretch forming is a sheet metal forming process in which the sheet metal is intentionally stretched and simultaneously bent to have the shape change. It is a type of cold drawing. Stress-induced is mainly tensile. Coining: In this chapter, various types of bulk metal forming processes are described. The main processes including rolling , extrusion , and forging with their sub-categories are covered. This motivates research of the novel process class sheet bulk metal forming (SBMF). .
