Testing of DISAL D240 and D420 Ceramic Tool Materials with an Interrupted Cut Simulator

This paper presents a solution for ceramic cutting tools availability in interrupted machining. Experiments were performed on a special fixture - the interrupted cut simulator. This fixture was constructed at Department of Machining and Assembly in Ostrava. The goals of the tests were to contribute to the wider usage of these cutting materials in machining, especially in interrupted machining. Through the centuries, producers of ceramic cutting tools have taken big steps forward. Namely, increasing durability in maintaining high levels of strength and hardness lends an advantage. Some producers of these materials advise cutting inserts for interrupted machining at the present time.
