It is shown that the components of cutting forces and energy consumption are smaller, and the accuracy and productivity of processing are greater, the greater the cutting coefficient, which is determined by the ratio of the tangential and radial components of cutting forces. On this basis, optimal technological solutions for mechanical processing of high-precision machine-building products, including optimal parameters of the cutting mode and characteristics of cutting tools, were established. The obtained theoretical solutions were confirmed experimentally, which indicates their reliability and the possibility of practical application. Based on this, new approaches to the development of technological processes of high-precision mechanical processing on metal-cutting machines of the "machining center" type with the use of cutting blade tools with wear-resistant coatings are substantiated. Specific examples of the creation of new technological processes of mechanical processing are given. It has been established that when processing high-precision holes in parts of hydraulic equipment from difficult-to-machine materials, it is effective to use modern technologies of high-speed boring and milling of holes, which allow to significantly increase the indicators of accuracy, quality, roughness and productivity of processing. Thanks to the application of these technologies, in a number of cases it was possible to eliminate inefficient grinding and abrasive operations from the technological processes of processing. As a result, a 2- to 3-fold reduction in processing time was achieved. Product Description popup.authors Novikov Fedir V. popup.nrat_date 2024-11-20 Close
