Mechanical study in drilling of heat resistant austenitic stainless steel
TypeCommunications avec actes
Machining of difficult-to-cut-materials like heat resistant stainless steels leads to the rapid tool wear and tool failure. The analysis of drilling process of these steels is even more difficult as it is not easy to investigate the cutting process at the drill tip. Therefore for this critical operation, modelling of cutting forces is very important. The study of the mechanical loading is based on the cutting tool geometry variation along the cutting edge. This study aims to investigate the drilling of heat resistant stainless steels with two geometries of twist drills, by analyzing specific cutting energy and forces at a global and a local scale.

Phenomenological study of multivariable effects on exit burr criteria during orthogonal cutting of AlSi alloys using principal components analysis RÉGNIER, Tristan; FROMENTIN, Guillaume; D'ACUNTO, Alain; OUTEIRO, José; MARCON, Bertrand; CROLET, Arnaud (ASME American Society of Mechanical Engineers, 2018)During machining, burrs are produced along a part’s edges, which can affect a final product lifetime or its efficiency. Moreover, time-consuming and expensive techniques are needed to be applied to remove such burrs. ...
