STUDY OF THE FORMS AND PURPOSE OF MACRO-RELIEF ON THE WORKING SURFACES OF CYLINDRICAL PARTS

Modern trends in engineering and agricultural industry emphasize the importance of using methods and tools to improve the reliability of individual parts and products as a whole, as well as to reduce the cost of products. The reliability of machine parts is determined by a number of parameters, such as strength, wear resistance, vibration and thermal resistance. In order to achieve these criteria for the reliability of machine parts, it is necessary to take into account various manufacturing methods and improve material processing technologies. An important aspect is also the use of composite and innovative materials that can significantly improve the characteristics of products. In addition, the introduction of automation and digital technologies allows to optimize production processes and reduce the probability of defects. The study of the forms and purpose of macroreliefs on the working surfaces of cylindrical parts is an actual problem in the field of metalworking and mechanical engineering. The subject of analysis was the properties and effectiveness of macroreliefs in the metalworking process, in particular their influence on the quality and functionality of products. The work includes an overview of various types of macroreliefs, their purpose and application in production conditions, taking into account the specific requirements of the technological process. The methods of forming macroreliefs, including processing technologies and their influence on the technical characteristics and quality of the final product, are highlighted. The results of the study showed that the use of macroreliefs can improve the technological capabilities of processing parts, ensure an increase in their strength and stability, as well as improve the appearance and aesthetics of the product. The obtained results are of practical importance for engineers and designers engaged in the development and production of cylindrical parts in various industries, such as automotive, mechanical engineering, aerospace and other industries where it is important to achieve optimal quality and production efficiency.
