ABSTRACT

Purpose. Identification and systematization of the main technological problems that arise when processing complex-profile parts, as well as development of recommendations for increasing the efficiency of production processes.

Methodology. Analysis of literature sources on modern methods for processing complex-profile parts, in particular machine tool and additive technology, systematization of problem areas: tool wear, cutting modes, surface defects, part deformations, complexity of accuracy control.

Research results. Key factors that directly affect the quality of processing complex-profile parts have been identified: structural geometry of the part, physical and mechanical properties of the material, cutting modes, rigidity of the technological system and tool quality. A systematized list of technological problems that require priority solutions to increase production efficiency has been formed. The results allow us to determine the priority areas for the modernization of technological processes and the adaptation of production equipment to complex products.

Scientific novelty. The work provides a systematic analysis of technological problems in the processing of complex-profile parts, which includes the relationship between the geometry of the product, material properties and cutting modes. This allows us to predict the surface quality at different stages of design, increasing the accuracy of the technological process.

Practical significance. The results of the study can be directly used in the development and adjustment of technological and design documentation for the manufacture of complex-profile parts from difficult-to-machine materials. Systematized technical problems and established factors of their occurrence are expedient to be used in the selection of cutting modes, tooling, schemes of basing and fastening of workpieces, as well as in the modernization of technological processes of mechanical processing. An actual basing scheme for a part of the conical shell type is presented.

Keywords: complex-profile parts, machine processing, cutting modes, surface quality, technological process.
