Study of the methods and conditions of forming cutting elements of carbide tools for milling processing of composite non-metal materials

Abstract

Among the requirements for modern structural materials include weight reduction, increase in stiffness and strength, the maximum life of manufactured products in various operating conditions, high reliability created from such materials. The listed requirements, as a rule, are provided at the stages of material selection and improvement of the technology for manufacturing products. Trends in the development of industry are aimed at the transition to the use of composite materials as a construction material that meets the complex of the listed requirements.

Recently, the proportion of use of composites in engineering, automotive, power engineering, shipbuilding, woodworking, machine-tool construction, construction, rocket, aerospace, chemical and petroleum industries has significantly increased. Achievements in the field of application of products made of composite materials largely depend on the improvement of production technologies for elements of various structures made of composite materials. Composite materials are metallic and non-metallic matrices (bases) with a specified distribution of reinforcers (fibers, dispersed particles); this effectively uses the individual properties of the components of the composition.

The most important technological methods for manufacturing composite materials are: impregnation of reinforcing fibers with a matrix material; forming in the mold tapes of seals and the matrix obtained by winding; cold pressing of both components, followed by sintering; electro-chemical coating of the fibers followed by pressing.

In this regard, one of the promising areas of development of the scientific and technical complex of the country is to increase the efficiency of processing modern composite materials with a blade tool in order to expand their field of use. There is a need to study methods and ways to improve the performance of the tool, to create new design solutions with high performance characteristics, to find rational conditions for its operation, ensuring the required quality of manufactured products. The problem of effective and high-quality technological preparation of cutting tools for processing composite materials is becoming urgent.
