This article deals with effect of thermal load to the mechanical forging press. Main topic is assessment of displacement on each part of mechanical forging press caused by thermal load. Accuracy of forged part and durability of press is highly influenced by this displacement. Correct settings of thermal simulations lead to proper setting of clearances in structure of mechanical forging press, specially clearance between lower and upper die and in guidance of ram. This can be done generally for all size of press.

“…The work [33], in turn, performs an analysis of the forging quality by way of applying visual measurement and control systems, especially visual systems. The literature extensively discusses the application of the measurement and control systems in the analysis of the state of the forging tools [4,5,8,24,30]. For example, the work [8] analyzes and points to (mainly based on the numerical calculations) the most crucial points, for different types of presses, where the highest stress concentrations occur, as well as the areas where one should expect failure.…”

The performed analyses of the level of technological solutions in the die forging processes show that, in a great majority of processes, the die forging production takes place in the traditional non-automatized way, on separated forging unit stations, where all the

Forging is a primary manufacturing process used in several manufacturing industries. Aircraft and automobile industries are manufacturing products with high‐dimensional accuracy and quality that are highly precise or near the required shape. Customers require products that are free of cracks and fulfill their functional requirements. This leads to the advancement of the forging process due to its ability to form complicated and intricate shapes. Herein, a detailed review of the aspects of forging is given in which the optimization of factors like preform design, forging conditions, workpiece dimensions, die design, lubricant properties, and thermal treatment parameters are discussed, enhancing the tool life and forging quality of the product. The selection of die‐forging tool material and methods for enhancing the surface quality of forged products are also reviewed. The article also presents methods for measurement of forging quality, tool life, machine effectiveness, forging image acquisition, and forging parameters, which can significantly reduce the risk of error at every step of the forging process. This review serves as a reference for researchers to increase production rate, enhance the effectiveness of measurement system, and improve the quality of forged products with technological advancement.
