THE POSSIBILITY OF INCREASING THE PRODUCTIVITY OF DRY TURNING AND BORING OF METALS WITH A MULTISTAGE BLADE CUTTER

Abstract

Processing of external and internal surfaces with a turning passing or boring cutter is one of the main and common types of mechanical processing of materials by cutting with a blade tool, which is widely used in various branches of mechanical engineering, automotive, shipbuilding, and aircraft engineering. It is shown that the main problem of the dry turning process is its low productivity. It is proved that an additional reserve for increasing its productivity can be the use of a turning passing or boring cutter with a multistage blade. A virtual laboratory has been developed in the LabVIEW software environment to establish the possibility of improving the productivity of dry turning and boring of metals and alloys, as well as their quantitative assessment for various numbers of cutting stages of a multi-stage cutter compared with the turning and boring process with a conventional cutter using a coolant. It has been found that the use of a cutter with a multistage blade, compared with the processes of turning and boring metals and alloys with a conventional cutter with the use of coolant, allows the dry turning of these metals with a simultaneous increase in processing productivity up to 28%. The results obtained can be used in the metalworking industry, which will allow, in addition to increasing processing productivity, to improve the environmental friendliness of production of various machine parts. Research in this area is going on. In order to determine the optimal modes of dry turning of metals with a multistage cutter, it is planned to conduct comprehensive virtual studies of this process using the methods of mathematical planning of experiments. The developed virtual device has a user-friendly interface and will find application both in the design processes of multistage cutters. It can be useful to undergraduates, graduate students and researchers of engineering specialties when conducting their research. The author is ready to immediately provide the virtual device he developed in the LabVIEW software environment to all the interested parties.
