The processing of difficult-to-process materials by cutting is a problem for many domestic machine-building industries, which is accompanied by material costs and low productivity. A number of such materials include titanium alloys. The study of the issue of mechanical processing of titanium alloys in the conditions of domestic machine-building industries has shown that the most significant problem is low productivity and high wear rate of the cutting tool. It is also known that titanium alloys have a very significant disadvantage – poor machinability, which is explained by the following characteristics of the material: - low thermal conductivity, which is why most of the heat is transferred to the cutting tool during the cutting process; - high tendency to stick and bully; - the appearance of jerks during milling, which lead to damage to the treated surface; - low vibration resistance during processing due to the instability of the plastic deformation process. To solve this problem, the processing of titanium alloys by high-speed milling is proposed. The idea of the project is to increase the efficiency of using the high-speed milling method for processing titanium alloys by creating a reference base for choosing cutting modes, cutting tools and the material of its cutting part

The aim of the project is to improve the manufacturing quality of titanium alloy parts by improving high–speed machining technology

2025 - Problems of mechanical processing of titanium alloys will be revealed. The disadvantages of existing methods and metal-cutting tools will be identified, as well as the requirements imposed on them by production. The physical and mechanical properties of titanium alloys will be determined. To popularize science, disseminate information about the results, increase the likelihood of their implementation and commercialization, a web page will be created for the project on the website of Karaganda Industrial University, which will contain all the brief information about the project and links to relevant profiles, a list of publications (with links to them) and patents; information for potential users. The information on the website will be updated regularly, at least 2 times a year, as new information about the project becomes available. 2026 - The proposed cutting modes will be considered with their impact on quality indicators and a planning matrix will be provided. Optimal cutting modes and patterns of their influence on quality indicators will be established. The hardness and depth of the hardened layer will be determined. At least one (1) review will be published in a peer-reviewed foreign or domestic publication recommended by the COC. 2027 - Patterns of temperature influence on quality indicators will be established. The most stressed part of the structure will be revealed. As a result of the project, high-speed processing technology will be improved to improve the manufacturing quality of titanium alloy parts, optimal cutting modes and impact on quality indicators will be established, and a reference base will be created on the selection of cutting modes, cutting tools and the material of its cutting part when processing titanium and its alloys. Methods of computer modeling of quality indicators during processing by high-speed milling of titanium alloys will be developed, as well as a study of the stress-strain state of parts, the design of working mills, as well as their cutting parts during processing. Information about the results of the work among potential users, the community of scientists and the general public will, first of all, be disseminated through the personal participation of performers at prestigious international scientific conferences, where representatives of leading companies in the industry are always present and there is an opportunity for effective dialogue on the spot. The obtained research results will be used by bachelor's, master's and PhD students in the educational process and in conducting their scientific research in the field of material processing. The risks of obtaining low-quality products with the improvement of processing technology will be minimal, as there is a good foundation for predicting the desired result. STEP Design Bureau LLP will take direct part as a private partner, contributing financing in the amount of 1% of the project amount and helping in the implementation of the project free of charge. Recommendations on the use of high-speed milling technology for titanium alloys will be prepared and approval protocols signed. Will be published: - at least 1 (one) article or review in a peer-reviewed scientific publication indexed in the Science Citation Index Expanded and included in the 1st (first) quartile of impact factor in the Web of Science database and (or) having a CiteScore percentile in the Scopus database of at least 80 (eighty); - at least 1 patent for an invention and/or utility model (including a positive decision on it); - at least 1 (one) article in a peer-reviewed foreign or domestic publication recommended by the International Scientific and Scientific Council. At the same time, one of the articles should be classified as multidisciplinary (multidisciplinary or interdisciplinary practical application) on the tasks of enterprises from the real sector of the economy of Kazakhstan, and the project results should include design documentation prepared according to the Unified System of Design Documentation (hereinafter - ESCD). For domestic journals from list 1 of the KOKNVO that do not belong to the multidisciplinary category, journals from lists 1 and 2 of the KOKNVO that are indexed in two or more categories are counted. Also, according to the results of the project, at least 1 (one) doctor of philosophy (PhD) or a doctor in the profile will be trained, while defending a dissertation no later than 2 (two) years after the completion of the project

The problems of mechanical processing of titanium alloys are revealed. An analysis of the current state of manufacturing of titanium alloy parts and assemblies at domestic machine-building enterprises has shown that their use continues to expand due to a combination of their properties such as low density, high corrosion resistance and strength characteristics. Such materials require high costs and lead to a decrease in the rate of production, its serious rise in price. The disadvantages of existing methods and metal-cutting tools have been identified, as well as the requirements imposed on them by production. A review of domestic and foreign publications has shown that mechanical processing of titanium alloys remains one of the most labor-intensive tasks in modern mechanical engineering. In this regard, further research on improving the designs of cutting tools and optimizing the machining modes of titanium alloys remains relevant, not only at domestic enterprises. The physicomechanical properties of titanium alloys, which are the most common in Russian engineering, have been determined. The data obtained form the basis for choosing the optimal technological modes of machining and allow us to correctly substantiate the requirements for tools and equipment for the production of titanium alloy parts.
