Abstract

The possibility to improve the conditions of cutting rotary workpieces with intermittent areas by applying conventional tool materials is limited. However the use of tools with working members made from polycrystalline ultra-hard materials (composites) can be very efficient, provided that a negative influence of load impacts on the tool point and the major cutting edge at the moment of the tool lead-in is mitigated.The described method of turning (boring) intermittent surfaces offers more rational conditions for the contact between the tool cutting member and machined workpiece surface and permits eliminating negative effects of impact loads on the tool point. Proper conditions of cutting intermittent surfaces by tools made from 03 composite (petbor) or 10 composite (hexanite-r) can improve machining efficiency by up to 25% due to the intensification of cutting operations as well as to decrease tool purchase expenses by about 20%.
