“…3. Ring rolling process [7] Special forging includes roll forging, cross wedge rolling, radial forging, liquid die forging and other forging methods, which are more suitable for the production of parts with special shapes. For example, roll forging can be used as an effective preforming process, which can greatly reduce the subsequent forming pressure.…”

With the vigorous development of high-tech industries such as aviation and aerospace, new challenges have been brought to the traditional forging process. Forgings with a single structural feature and conventional forging processes in the past can no longer fully meet the development of contemporary industry. Therefore, it is urgent to develop new forging processes to meet the higher requirements for forgings. First of all, this article classifies the traditional forging processes, which helps to better understand the different types of forging processes. Then, the analysis of different types of forgings and their forming processes will help to better understand the forming characteristics of different methods of improvement. Comparative analysis found that the selection of forging process and route should fully consider the shape and size of the forgings. In actual production, often one type of forging may have multiple types of shape features. The complexity of the structure makes it impossible to obtain such forgings through only one type forging process or one-step forging. Greatly increased the difficulty of forging, limiting its development and application. Therefore, It is necessary to develop multi-types and multi-steps forging processes. And it is urgent to do further research on the metal forming mechanism and defect generation mechanism of complex forgings in the forging process.

“…The process carried out to prepare data before classification is the process of normalization. Normalization is done to equalize the shape of the data that is not uniform and make the data have a range from 0 to 1 (Zhu et al, 2023). Normalization is also interpreted as changing data into Gaussian data or equivalent value equations (Peterson, 2021).…”

Many smartphones today need to be more precise about choosing one that suits the user's needs. In fact, smartphone sellers sometimes need help recommending smartphones that suit buyers' needs. Generally, buyers search for smartphone specifications with keywords they desire, but the results appear different from what they expected. Users need the main specifications, such as Random Access Memory (RAM) and Read Only Memory (ROM) capacity, battery, and high camera quality. This research aims to implement the K-Nearest Neighbor (KNN) algorithm for recommendation smartphone selection based on the criteria mentioned. The data test results show that the combination of KNN with four criteria has good performance, as indicated by the accuracy, precision, recall, and f-measure values of 95%, 94%, 97%, and 95%, respectively.

“…A review of the specialized literature showed that the vast majority of publications concern the radial-axial rolling method (for instance, recent publications [ 11 , 12 , 13 , 14 , 15 , 16 ]), while there are relatively few studies on the radial rolling process. Among them, there is a limited number of publications presenting the research results on the influence of the process parameters on the cross-section deformation and the final ring height (which determines the ring diameter) in the radial rolling process.…”

The rolling process of rings is a commonly used method for producing annular forgings. There are two primary types of this process: radial-axial rolling and radial rolling. This article presents the research results regarding the latter, in which obtaining a product with the assumed dimensions constitutes a major problem. In industrial practice, the process parameters are based on the experience of technologists and/or by trial and error. This is why the authors considered it justified to undertake the research aimed at determining the influence of the main process parameters, that is, preform temperature and tool speed, on the shape and dimensions of the cross-section, which determine the internal and external diameters of the rolled ring. The research was based on numerical simulations and experimental studies. The results obtained proved that the higher the feed speed of the main roll, the greater the change in the cross-sectional height during rolling, and the smaller the cross-sectional deformation (the so-called fishtail). Nevertheless, a higher preform temperature reduces the final height of the ring and reduces cross-section deformation. On the basis of the obtained test results, guidelines for the process design were postulated, considering the influence of temperature and speed parameters on the final dimensions of the forging and the dimensions of the preform.
