In stamping processes, metal sheets are deformed to desired shapes and dimensions under high stamping forces at room temperature. Because of its high productivity and acceptable accuracy of shape and size, the stamping process is extensively used in various industries. In motor manufacturing, stamped housings and endbells are typically used for small-size, large-volume, and ordinary motors such as vacuum cleaner motors (Figure 5.10).

Sheet metal forming is a wide subject that has many intricacies that require an indepth knowledge. Only an overview will be covered in this section. There are several types of sheet metal-forming processes, such as drawing, rolling, hydroforming, stretch forming, explosive forming, plastic forming, stamping, etc., that are covered in standard manufacturing technology textbooks [21, 22]. Drawing, rolling and hydroforming have either been discussed previously or will be covered briefly in a later section. This section focuses on stamping. Stamping is a process that involves pressing sheet metal into a die to form an infinite number of shapes. Many body parts in an automobile are made this way. Stamping is a process where every second counts. Even a lag time of 0.1 of a second can be considerably costly over many years of operation.
Cost Estimating for Various Manufacturing Processes

One of the most widespread manufacturing processes, stamping is used to make parts for a multitude of purposes. It can range from very small parts, such as door hooks, all the way to things like car panels. Similarly, the machines used to make these parts can vary dramatically in size, but the stamping process can boil down to two main categories: transfer and progressive die (see progressive die in Figure 4.14).

Stamping is a sheet metal forming process that involves the pressing of the sheet metal under high pressure and speed between a punch and die carrying the desired shape (Fig. 4). It is a low-cost method that can be used for high-volume manufacturing of sheet metals. Stamped parts have shown good dimensional accuracy and remarkable surface finish, as well as excellent mechanical properties compared to other fabrication methods.[140] Furthermore, economical mass production of high-performance BPs can be achieved through the application of state-of-the-art CNC micromachining techniques to the fabrication of long life stamping dies.[141] Thus, production of PEMFC BPs by stamping of thin metal foils has become a popular option to reduce weight and volume of FC stack, since the need for a separate water cooling plates can be avoided in stamped BPs.

A stamping press (Figure 8) is a metal working machine used to shape or cut metal by deforming it with a die. This use case focuses on press machine maintenance, monitored continuously by a broad and diverse range of intelligent sensors that keep track of its operational conditions.

Stamping is widely used in transportation industries, such as automobiles, aircraft and ships. Taking the automobile manufacturing industry as an example, most body panels involve stamping. However, defects such as wrinkling and cracking will occur during the stamping process. These defects are caused by the unsatisfactory arrangement of process parameters in stamping (Lan et al. 2004). Therefore, optimizing the stamping process parameters is necessary to improve the forming quality of stamping parts. In recent years, optimization of the stamping process parameters has been studied by many scholars. Kubli and Reissner (1995) took the drawbead of the fender as the object of study and improved the forming quality of the fender by optimizing the shape parameters of the drawbead. Nakamura et al. (1998) used a sensitivity analysis method in the optimization of die parameters to reduce the seven design parameters affecting the objective function to two, which accelerated the optimization process and improved the optimization efficiency. Naceur et al. (2001) investigated the effect of drawbead resistance on stamping parts, and improved the sheet formability by optimizing the drawbead resistance. Browne and Hillery (2003) carried out a large number of experiments with cup-shaped parts as the research object, studied the effects of process parameters, screened out the key process parameters that affect the forming quality and, finally, improved the forming quality of cup-shaped parts by optimizing the screened process parameters. Azaouzi et al. (2008) developed an automatic optimization design platform by combining heuristic algorithms and finite element software, and applied the platform to optimize the design of sheet forming process parameters to improve the forming quality of the sheet. Ma and Huang (2014) studied the influence of stamping process parameters on the forming of the automotive lower floor board, and improved the forming quality of stamping parts by optimizing the friction coefficient and blank holder force. Wu, Wang, and Wan (2019) took the fender as the research object, and improved the performance of the fender by optimizing its stamping process parameters. Wu et al. (2021) investigated the influence of the friction coefficient on the stamping quality of V-clamps, and optimized the friction coefficient of the mould surface to improve the performance of V-clamps. All these studies demonstrate that the formability of the part can be effectively improved through the optimization of stamping process parameters.
