Experimental Analysis and Geometrical Modeling of Cutting Conditions Effect in 5 Axis Milling with Ti6Al4V Alloy
TypeCommunications avec actes
The 5 axis continuous milling is an advanced technique for free-form surfaces manufacturing. In finishing, this technique uses ball-end or hemispherical milling cutter. This type of operation for 5 axis milling allows the possibility to tilt the tool with two different angles. As a consequence, a mass of geometrical configurations exists and establishing accurate parameters is quite difficult to define. A geometrical model has been developed to find the effective cutting diameters and cutting speed on the cut and the finished surface. After an experimental validation, this study proposes an analysis of several 5 axis milling configurations in order to perform this technique.

PRAT, David; FROMENTIN, Guillaume; POULACHON, Gérard; DUC, Emmanuel (ASME, 2016)Five-axis milling with a ball-end cutter is commonly used to generate a good surface finish on complex parts, such as blades or impellers made of titanium alloy. The five-axis milling cutting process is not straight forward; ...
DENGUIR, Lamice; BESNARD, Aurélien; FROMENTIN, Guillaume; POULACHON, Gérard; ZHU, Xiaowen (Taylor & Francis, 2014)One of the criteria mastering the choice of a cutting tool is its wear resistance. In this paper, tool life is treated: on one hand, the study aims to classify the performances of the edge preparations in terms of ...
FROMENTIN, Guillaume; POULACHON, Gérard; MOISAN, Alphonse (Hermes - Lavoisier, 2006)While threaded holes made by cutting taps result in material removal, in form tapping, the tap displaces the work material by plastic flow to form the thread section. The aim of the present work is to study, both experimentally ...
BAIZEAU, Thomas; CAMPOCASSO, Sébastien; FROMENTIN, Guillaume; ROSSI, Frédéric; POULACHON, Gérard (Elsevier, 2015)In the case of hard machining of steels, negative rake tools generate compressive deformation and high temperature under the cutting edge, leading to phase transformation or ”white layers”. The resulting surface integrity ...
FROMENTIN, Guillaume; POULACHON, Gérard (Springer-Verlag, 2010)Thread milling is a method which is increasingly used for machining thread. For this operation, a helical interpolation is required. Furthermore, the thread mill is a tool whose geometry is rather complex. Its envelope ...
