xml:lang="en"><p>The wear resistance of PCD cutting elements of GES 1313  model of E6 in the form of cylinders with a diameter of 13.44 mm  and a height of 13 mm was studied when cutting granite and abrasive  wheels by turning at various speeds, with determining the optimum  cutting speed and obtaining comparative cutting data for Mansurovsky Granite and abrasive wheels of 64C (SiC) grade in order to  develop recommendations on the test conditions for PCD cutting elements. For the characteristics of wear resistance, the ratio of the  decrease in the volume of diamond layer to the volume of the processed material (or the amount of the processed material) was taken  into account for the same degree of wear of the cutting element. In  the first case, the wear resistance was estimated in relative units, in  the second case in cm3 according to the wear of the back surface  in mm. When cutting granite, the cutting speed was changed from  80 to 320  m/min, when cutting abrasive wheels, the cutting speed  was 500  m/min. To calculate the volume of PCD cutting elements in the “Compass  3D” program, 3D  models of their worn parts were  designed, a calibration plot of the volume versus the wear size on the  back cutting surface of the PCD was constructed. The cutting angle  was –22°. It was shown that the change in the volume of the worn out  part of the PCD is less than accuracy of the wear pad measurement to  a wear value of 0.8  mm when the cutting angles varies from –20 to  –25. It was found that an increase in the cutting speed from 80  m/min  to 160  m/min while cutting granite in 12  times decreases the wear  resistance of PCD cutting elements; the relative volume wear of PCD  cutters when cutting granite is (0.01  –  0.02)·10–6, which is 20  times  less than at cutting abrasive wheels of 64C grade. The relative wear  resistance of PCD cutters when cutting abrasive wheels of 64C grade  does not depend on the degree of blunting on the back surface to  1.4  mm, this technique can be recommended as an express method  for determining the wear resistance of PCD. The implemented method with the use of “Compass 3D” program or similar engineering  programs to calculate the volume of worn out part of the PCD can  be used to estimate the relative abrasion resistance of abrasive and  cutting materials.</p></trans-abstract><kwd-group
