Modern approaches to abrasive machining of carbon-carbon materials and tools for its implementation

The article discusses carbon-carbon composites, which are promising materials for the aerospace, defense, and automotive industries due to their unique combination of high strength, heat resistance, and low density. However, their machining is challenging due to their complex microstructure and abrasiveness, which leads to defects, tool wear, and chip removal problems. In this regard, the purpose of this work is to analyze the main challenges in machining C-C composites and to consider possible approaches to minimize these problems.The aim of the study is to improve the characteristics of abrasive cutting tools in the task of cutting composites using additive manufacturing methods.The article presents an overview of the use of C-C composites in various industries, including thermal protection systems, brake discs, gas turbine components, etc. The main problems associated with their processing, such as material delamination, cutting tool wear, and chip removal, are discussed. The influence of various factors, including mechanical loads, thermal effects and tool design, on the occurrence of these problems is analyzed.The results of the study show that effective machining of C-C composites requires the use of specialized cutting tools, methods of control and monitoring of the tool condition, as well as the use of alternative machining methods. Approaches to minimize the problems associated with machining, including optimization of the cutting tool using additive technologies, are proposed.The obtained results of the literature review can be used in modeling the cutting process and for optimizing the parameters of the cutting experiment. The results also show the relevance of the selected problem and the possibility of further application.
