Abstract

The paper deals with testing of ceramic cutting tools with an interrupted machining. Tests have been performed on fixture – interrupted cut simulator constructed at Department of Machining and Assembly, FME, VŠB-TU Ostrava within the scope of the Czech Science Foundation project. The criterion of tool wear is either destruction of cutting tool or 6000 shocks. Testing cutting tool material used in this research is ceramic cutting tool produced by Tungaloy Company. Tested machined materials are 13MoCrV6 and C45 steels. The cutting speeds (408 and 580 m/min) and cutting feeds (0.15; 0.2; 0.25 and 0.3 mm) are investigated with variable parameters whereas the cutting depth is a constant parameter. The pictures of index-able inserts and graphs of dependence at variable cutting speed and cutting feed are shown as a result of a conducted investigation.
