RISCO-ALFONSO, Ricardo del; PEREZ-RODRIGUEZ, Roberto; MOLINA, Arturo  and  QUIZA-SARDINAS, Ramón. BIDEMICS ceramic tool wear in the machining of AISI 316L steel. Ingeniería Mecánica [online]. 2019, vol.22, n.1, pp.41-48. ISSN 1815-5944.

The new ceramic tools, intended for the machining of thermo resistant materials, can be a viable option for the machining of austenitic stainless steels. The present work aims to show the results of the behavior from the wear point of view, of a ceramic tool BIDEMICS, during the machining in dry and using Minimum Quantity of Lubricant (MQL), of the steel AISI 316L. An experiment based on a dry turning operation with MQL of a bar of 25 mm in diameter was developed, varying the cutting speed in three levels, 200 m/min, 300 m/min and 400 m/min and the advance in three levels 0,1 mm/rev, 0,15 mm/rev and 0,2 mm/rev. In the study, the wear behavior of this tool was evaluated and the models that describe the initial wear rate were determined.

Keywords : cutting tool; ceramic; wear; AISI 316L; primary wear velocity.
