A REVIEW AND ANALYSIS OF THE INFLUENCE OF TECHNOLOGICAL PARAMETERS ON THE EFFICIENCY OF PROCESSING HARD-TO-MACHINE MATERIALS
The article analyzes modern technologies for machining workpieces of hard-to-machine materials with a hardness parameter higher than 45 HRC (Rockwell hardness). It is shown that the mechanics and thermodynamics of the forming process in such materials are subject to specific laws of cutting theory, which have systemic differences from the processing of traditional engineering materials. The advantages and disadvantages of machining chromium-nickel alloys using CNB inserts instead of grinding are analyzed.
