The performance of this method is tested by 107 experiments derived from different conditions in the sheet metal stamping process. The artificially created defects can be detected with a success rate of 96.3%. The method seems to be useful to monitor a sheet metal stamping process in practice. A new method for diagnosing sheet metal stamping processes is presented based on the fact that during the stamping process, the workpiece absorbs energy to deform and is converted into thermal energy, which can be acquired using an infrared (IR) camera. In this paper, a new approach is proposed using the 3-D thermal energy distribution of the workpiece. The .
sheet metal stamping procedure
The proposed method is applied to fault diagnosis of sheet metal stamping operations. Stamping process is one of the most commonly used manufacturing processes in modern manufacturing. Aiming at meeting the ever-increasing demands for product quality and productivity, a number of monitoring systems have been developed [19], [20], [21], [22]. Sheet metal stamping process is widely used in industry due to its high accuracy and productivity. However, monitoring the process is a difficult task since the monitoring signals are typically non-stationary transient signals. In this paper, empirical mode decomposition (EMD) is applied to extract the main features of the strain signals .
This chapter presents research on monitoring and diagnosis of sheet metal stamping processes. It consists of five sections. Section 8.1 introduces some of the authors’ research on the sheet .Sheet metal forming continues to be one of the topics of interest to the manufacturing community, and recent studies have investi-gated assumptions made in analytical modeling of failure mecha-nisms of forming [1]. Previous research in quality and process monitoring of stamping processes has also shown that the repeat- To improve process monitoring in the sheet metal stamping process, it is of interest to measure the contact pressure distribution at the workpiece-tool interface.
Traditional signal processing and conventional machine learning methods have been employed in several studies on the stamping processes and tool diagnosis. . monitoring sheet metal stamping is . Galling wear in sheet metal stamping processes can degrade the product quality and adversely affect the mass production. Studies have shown that acoustic emissions sensors can be used to measure galling. . A large number of studies have investigated fault diagnosis or condition monitoring of stamping tools using a variety of sensors such as . The proposed method is tested in condition monitoring of sheet metal stamping processes. A large number of experiments were conducted. In particular, two cases are presented in detail. In sheet metal forming processes, any disturbance as a slight change in the mechanical properties of the material can be the reason for the occurrence of defects without changing any other of the .
The stamping process has more than 40 process variables [2] which can be classified into four broad categories: blank material characteristics, die condition and setup parameters, press performance and working parameters, and the interaction variables. The stamping procedure is a complex physical process where it is performed at a very short time .
