THE IMPACT OF THE RESULTS OF PRODUCTION TESTS OF CARBIDE CUTTING TOOLS HARDENED BY A MAGNETIC-PULSE TREATMENT ON INCREASING THE EFFICIENCY OF THE TECHNOLOGICAL CUTTING PROCESS
AbstractThe subject matter of the article is the process of hardening cutting tools for heavy machines. The goal of the work is to increase the operating life, reliability, durability and wear resistance of carbide cutting tools due to magnetic-pulse treatment. The tasks were solved: the main factors affecting the change in wear resistance of a carbide treated with a pulsed magnetic field; the impact of the test results of carbide cutting tools hardened by a magnetic-pulse treatment (MPT) on the productive capacity was studied; the MPT impact on the tool durability indices; the interrelation of the MPT parameters, cutting parameters and production efficiency were studied. The following results were obtained: the production tests of carbide cutting tools showed that magnetic-pulse treatment contributes to improving the wear resistance of cutting tools, reducing the coefficient of durability variations, increasing gamma-percentile stability, reducing the amount of chipping and breakage in the area of tool breaking-in. The MPT application enables optimizing cutting conditions in performance rate, cost of operation and tool expenses. It was found out that under difficult cutting conditions, the cutting mode should be optimized in the depth of cut, taking into account the spread of tool durability. Conclusions. A magnetic-pulse treatment contributed to increasing the stability of tools by 1.2-2.0 times and decreasing the coefficient of durability variations by 1.3-3.1 times. The gamma- percentile stability of tools increased by 1.7 - 2.8 times; the optimum durability went up by 1.4-2 times, the optimal feed – by 1.15-1.3 times. The dependence of the performance of machining with a cutter after MPT on the magnetic intensity H, on the carbide resistance to rupture , on the amount of cobalt in a carbide and on the pulse frequency f was determined.
