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.

A generalised geometrical model of turning operations for cutting force modelling using edge discretisation CAMPOCASSO, Sébastien; COSTES, Jean-Philippe; FROMENTIN, Guillaume; BISSEY BRETON, Stéphanie; POULACHON, Gérard (Elsevier, 2015)The knowledge of cutting forces is of prime importance to ensure the success of cutting operations, the desired properties of the machined parts and therefore the functionality of the workpieces. Edge discretisation is one ...
