Abstract-Treatment of vnutrennih cylindrical surface plastic deformation is widely used in industry for the production of a large range of engineering products. In the processing method of burnishing of internal cylindrical surfaces of the steel bushings on the lathe-cutting machine with heating revealed that the roughness of the processed surface depends mainly on temperature and is almost independent of the processing speed. The result is a sealing material that improves the quality of the products. The degree of compaction depends on the amount of effort that is applied to the surface of the instrument.

The parameters of the cutting mode play an important role in ensuring the stability of cutting tools, quality and cost of products. Therefore, determining their optimal values is a primary task in the development of a technological process, and, therefore, the topic of research is relevant.When designing technological processes of metal processing, the task of choosing the values of cutting depth, feed and cutting speed inevitably arises. At this time, the cutting depth and feed are assigned depending on the requirements for the quality of the treated surface. After that, taking into account these parameters and the recommended limit values practically determine the cutting speed. The problem is the lack of analytical expressions for calculations of feed and nominal values of cutting speed.The analysis of the latest research and publications showed that a lot of attention is paid to the selection of parameters of the cutting mode. However, analytical methods for determining feed and cutting speed have not been created.The purpose of the article is to increase the accuracy of determining the parameters of the cutting mode based on the use of mathematical dependencies.Based on the analysis of the geometry of the formation of the height of the roughness of the machined surface, the work presents the method of analytical calculation of feed when determining the parameters of the cutting mode. For the first time, a general approach that relates thefeed value and the surface roughness parameter was proposed. Analytical dependencies and an algorithm for applying one of them that corresponds to a specific situation have been created. A mathematical model for determining the optimal value of the cutting speed is proposed. This allows you to solve the problem of calculating parameters of the cutting mode. In the work, for the first time, an analytical calculation of feed during metal cutting is proposed. A mathematical model for determining the optimal value of the cutting speed, taking into account the work of blade wear, is proposed.

The increase in the share of physical and technical processing methods in the arsenal of deburring technologies used in modern production is associated both with the use of difficult-to-machine materials, such as beryllium bronze and the 29 NK alloy, and with the need to solve technological problems for the production of small-sized products with hard-to-reach surfaces. The aim of the study is to improve the processes of blade processing of small-sized parts made of beryllium bronze and the 29 NK alloy to provide rational conditions for thermal pulse deburring. Surface samples were experimentally obtained after turning in different modes on a CITIZEN CINCOM K16E-VII automatic lathe equipped with an Applitec micromechanics tool. The surface quality and burr characteristics were examined using a JEOL JIB-Z4500 electron microscope and a ContourGT-K optical profilometer. The program Statistica 6 allowed processing of the results. The relationship between the parameters of the turning mode and the thickness of the root of the burrs formed on the machined surface, the limitation of which is one of the conditions for the application of the thermal pulse method, was established. The obtained empirical regression dependencies establish a rational range of cutting mode parameters, and the implementation of the formulated recommendations for setting blade modes ensures deburring by the thermal pulse method in compliance with the requirements of drawing under maximum processing performance.
