JUSTIFICATION OF INCREASING THE DURABILITY AND PRODUCTIVITY OF PRECISION PARTS USING LASER METHOD

Summary: The work summarizes and critically analyzes the existing criteria for optimizing the methods of increasing and restoring the surface hardness of precision parts of machines and devices, shows ways to improve and clarify them, and also attempts to select optimal methods for increasing and restoring the surface hardness of precision parts of machines and devices and develop a generalized model. Various methods for increasing and restoring the surface hardness of parts of machines and devices with increased surface hardness pose the most urgent problem of choosing the optimal option for specific production conditions from among various technological solutions. This necessitates a further study of methods for increasing and restoring surface hardness and is based on three criteria: applicability, durability and technical and economic efficiency. The solution to the problem of substantiating the optimal method for increasing and restoring the surface hardness of machines and devices should be carried out using properly selected optimization criteria, using controllable factors that have the greatest impact on the costs of the technological process.
