Analytical and experimental investigations on thread milling forces in titanium alloy
TypeArticles dans des revues avec comité de lecture
This study deals with the thread milling process that is considered a complex machining technique due to its elaborated tool geometry and its tridimensional tool trajectory. It needed advanced research on the threading process which has not been much studied. Previous studies focused on geometrical modeling or mechanistic modeling of the thread milling process. There is a need for a better understanding of parameter effects to accomplish a model that tends to be more realistic and includes local parameters. This investigation does the analysis of thread milling parameters: thread geometry, cutting conditions and tool angles, which can be applied to the tool optimization. The cutting forces and torque were measured and representative values of its variation were calculated and analyzed as response of the experiments. A geometrical analysis and an analysis of variance were employed for determining the influence of the factors and based on the results, it is proposed a physical understanding of the process.

ARAUJO, Anna Carla; FROMENTIN, Guillaume (Springer, 2018)Milling is a good option for manufacturing internal threads in hard-to-cut dental components due to lower cutting forces. In the case of a very small drilled diameter, the tool cannot be large enough to reduce tool deflection ...
ARAUJO, Anna Carla; FROMENTIN, Guillaume (Elsevier, 2017)Abstract Thread milling processes produces lower forces and residual stresses if compared to thread cutting by turning, as the cutting area is lower because the feed rate is not dependent to the cutting speed. In industry, ...
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 ...
FROMENTIN, Guillaume; POULACHON, Gérard (Springer, 2010)Thread milling offers interesting possibilities for machining internal or external threads. This machining technique uses a mill with a triangular profile for metric threads and a helical interpolation strategy. Thus, the ...
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 ...
