Testing of Greenleaf ceramic cutting tools with an interrupted cutting

Abstract

This paper will be dealing with a solution of ceramic cutting tools availability in interrupted machining. Tests will be provided on fixture - interrupted cut simulator. This fixture was constructed at Department of Machining andAssembly,VŠB–Technical University of Ostrava. Criteria of tool wear are destruction of cutting tool or 6000 shocks. Testing cutting tool material will be Greenleaf GEM-7 and WG-300 products. Cutting speed (408 m/min and 580 m/min) and cutting feed (0,15 mm, 0,2 mm, 0,25 mm and 0,3 mm) will be variable parameters and cutting depth will be a constant parameter ( = 1 mm). The main outputs of the tests will contribute to the wider usage of these cutting materials in interrupted machining. At the present time these materials are advised as cutting inserts for interrupted machining by some producers.
