During long-term operation of rotating parts of technological machines, which include tires and support rollers of rotary kilns, rolling surfaces lose their shape accuracy and quality. Built-in machine modules are used to restore large-sized parts in the form of bodies of revolution. Such repair work requires special technological approaches and careful preparation before starting. It is necessary to take into account the real geometry of the surface of the part being repaired, which may have shape errors in the longitudinal and cross section due to wear, and conduct a preliminary analysis of the state of the part. It is also necessary to take into account the large dimensions and weight of the workpiece, and the inconsistent position of its axis during rotation. The technologies used and mobile machines for carrying out these repairs still have drawbacks that do not allow for efficient processing and affect the accuracy and quality of the resulting surface. The solution to this problem can be the development of new models of machine tools for processing large-sized bodies of revolution, the design of which will be more perfect in comparison with the previous models. To achieve this goal, it is necessary to study and analyze the existing domestic and foreign models of mobile machines and the principle of their operation. The proposed new machine model should have sufficient static and dynamic rigidity, as well as have a module responsible for adaptive control of the machining process, which will compensate for unstable positioning of parts during machining.

The textbook provides the main stages, sequence and general methodology for designing technological processes for machining parts and assembling products in mechanical engineering. In the main sections, after the presentation of the elements of the theory, examples of their specific implementation are given. For undergraduate students studying in the areas of training 15.03.01 "Mechanical Engineering", 15.03.05 "Design and technological support of machine-building industries", as well as specialists studying in the specialty 15.05.01 "Design of technological machines and complexes", full-time and correspondence forms of study, mastering the methodology of technological design and performing course and diploma projects and works.
