“…Artificial intelligence algorithms, such as the artificial neural network (ANN), have been shown to produce better response models than the response surface method [36]. Artificial intelligence, with an adaptive-network-based fuzzy inference system (ANFIS), has been used to optimize an ultrasonic vibration-assisted sheet-metal-forming process [37]. Response surfaces were obtained where the interactions of the vibration amplitude with the forming force and the feed rate were evaluated.…”

Data acquisition and processing are areas of research in fault diagnosis in rotating machinery, where the rotor is a fundamental component that benefits from dynamic analysis. Several intelligent algorithms have been used to optimize investigations of this nature. However, the Jaya algorithm has only been applied in a few instances. In this study, measurements of the amplitude of vibration in the radial direction in a gas microturbine were analyzed using different rotational frequency and temperature levels. A response surface model was generated using a polynomial tuned by the Jaya metaheuristic algorithm applied to the averages of the measurements, and another on the whole sample, to determine the optimal operating conditions and the effects that temperature produces on vibrations. Several tests with different orders of the polynomial were carried out. The fifth-order polynomial performed better in terms of MSE. The response surfaces were presented fitting the measured points. The roots of the MSE, as a percentage, for the 8-point and 80-point fittings were 3.12% and 10.69%, respectively. The best operating conditions were found at low and high rotational frequencies and at a temperature of 300 ∘C. High temperature conditions produced more variability in the measurements and caused the minimum value of the vibration amplitude to change in terms of rotational frequency. Where it is feasible to undertake experiments with minimal variations, the model that uses only the averages can be used. Future work will examine the use of different error functions which cannot be conveniently implemented in a common second-order model. The proposed method does not require in-depth mathematical analysis or high computational capabilities.

“…This new market demand can be met using digital incremental forming [1][2][3], which is a new sheet metal flexible rapid prototyping technology [4][5][6]. In contrast to the traditional stamping forming, this technology can produce sheet metal parts with large forming limits and complex shapes without the use of a special die, or by simply using model support, which makes it ideal for rapid prototyping and small batch production [7][8][9][10][11].…”

The deformation force is an important factor affecting the forming accuracy of parts in the incremental forming process of sheet metal. This paper proposes an analytical calculation method of the deformation force based on pure shear deformation. After assuming and simplifying the factors affecting the deformation force, a graphical method is used to approximate the contact area between the forming tool and the sheet metal. A forming test is also designed. In addition, the deformation force is measured in the experiment, and its theoretical analysis value is compared with the actual measurement value of the forming test to validate the analytical method of deformation force calculation. The results show that the radial forming deviations are 28.5% and 22.5%, the axial deformation force deviations are 9.8% and 16.1%, and the forming force deviations are 6.3% and 10.3%, which demonstrates the effectiveness of using the analytical method to calculate the deformation force.

“…It is remarked that electro-pulsing integrated to ISF process causes a weakening of anisotropy behavior, which favors the increase of formability by delaying crack appearance and damage, improves the thickness distribution with similarity in rolling and transverse direction of the sheet plate. Naif Alharbi 31 and Cheng et al 32 applied ultrasonic vibration in incremental forming process; authors used a vibrated forming tool as depicted in Figure 6 at the aim to improve the formability and the quality characteristics of the finished product. It is denoted that due to phenomenon of acoustic softening the ultrasonic vibration caused an increase of thinning which helps forming deep workpieces and steep walls.…”

The constant need to improve manufacturing processes and production methods, with the aim of making these processes more flexible and precise, and subsequently solving problems of conformity, quality of manufactured parts and productivity, drives manufacturers to develop original manufacturing techniques. The incremental sheet metal forming process, one of these novel techniques, has attracted a great deal of attention in recent decades. This paper presents a review of recent work done in this area and captures ideas for future work based on studies conducted by several researchers. A review of advanced investigations considering the following terms of interest: process, tools, formability, modeling and simulation is developed. Overall, it can be said that ISF process still requires further research to exploit the fabrication of new materials such as novel nanocomposites and Functionally graded materials (FGM). Test the performance of 4- and 5-axis CNC machines to manufacture industrial parts. Finally, apply new hybrid technics at the aim to improve the geometric accuracy, formability and the productivity of ISF process.
