Solving the problem of cutting tools im-ports phase-out based on boosted physical parameters diagnostics of the cutting operation

The problems of cutting tools supply interaction from abroad due to sanctions rollout and new possibility of full-fledged replacement of these tools with the relevant cutting tools of domestic production are viewed. The results of linking comparative research of cutting geometry impact on physical parameters, comparing lamellar tooth material and coatings in lathe knives of various foreign firms and similar domestic lamellar teeth of the Kirovograd carbide materials plant using the modes of finish-turning, semi-rough and rough turning operations by means of the computer-aided diagnostics center, are presented. It is found that in most parameters, cutting tools of domestic manufacture is absolutely equal to the best foreign tools and can be recommended substitution-ally for various machine-building enterprises in Russia.
