IOP Conference Series: Materials Science and Engineering Vol. 91. P. 012058 (1-8)Abstract: The author designs an up-to-date rock cutter for mining machines and presents a matrix to determine its service life depending on the strength of the rock being broken. The dependence of the cutter service life on the strength of the rock being broken is proved. Advanced designs of rock cutters by the leading companies are described. The author develops an original design of a rock cutter which provides greater cutting surface, increased strength and prolonged service life. Pilot samples of the cutters ready to the test run are presented.
