ABSTRACT

Analysis of the tool work and refusals when heavy machines cutting shows the necessity to use methods of bulk modification for improving structural strength and fracture resistance of cemented carbide cutting plates. It is suggested to test cutting plates to assess the structural strength limit. The accelerated method to estimate theresistancetoscatteredcontactdamage and chipping resistance is developed.It is obtained that the pulsed magnetic field treatment(PMNF) of cutting plates (85% WoC,5% TiC, 10% Co) leads to a dependent on treatment regime increase in structural bending strength limit under static load. The PMTF allows increasing theresistancetoscatteredcontactdamage and chipping resistancefor cutting plates (92% WoC, 8% Co).It is shown thatphysical method of pulsed magnetic field treatment is promising for modification of tool materials
