The textbook provides the main stages, sequence and general methodology for the development of technological processes of mechanical processing of parts and assembly of mechanical engineering products. In the main sections, after the presentation of the elements of the theory, students are assigned project tasks. Many sections are accompanied by examples of their specific implementation. It is compiled to help students of engineering specialties of full - time and part-time education, mastering the methodology of technological design and performing course and diploma projects and works.

On the basis of a new approach to restoring the accuracy of parts with uncertain bases, mobile technologies for recovering the accuracy of large-sized parts without their dismantling in the workplace have been developed, which significantly reduces the cost of repairs. Much of the in-formation is devoted to the issue of the layout and design of the plug-in machine modules, al-lowing the implementation of mobile technologies. The design of machine modules is given. The new technology is consid-ered with reference to the equipment of cement plants (bandages and rollers of cement kilns). The technology can be extend-ed to large-sized parts of equip-ment of other industries.

The theme of design is the tech-nological process of manufac-turing a part or article, a tech-nological process of assembly or elements of both. Course design is the basis for independent work of the student when solv-ing a complex set of technologi-cal issues in the conditions of production and systematization and deepening of knowledge in general technical and special disciplines. It includes a compu-tational and explanatory note (PZ) with a full set of issues re-lated to technological design, with a concise, clear and techni-cally sound justification for all technical decisions taken in the project: the technological route of the workpiece, the technolo-gical setup of equipment or the RTC for CNC machines , tech-nological scheme of assembly of the product; operational tech-nological schemes of assembly.
