The guide is designed for young turners studying in vocational schools of labor reserves, as well as for beginner turners trained directly at production enterprises. A significant part of the materials of the reference book can be used in secondary schools when teaching students turning. The materials placed in the reference book make it possible to quickly find answers to questions about inter-operation allowances, tolerances and fits, cutting modes and cutter geometry for performing various turning operations, choosing the correct sequence of processing. Particular attention is paid to the issues of cutting at high speeds and high feeds.
