Analytical and experimental investigations on thread milling forces in titanium alloy
Article dans une revue 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.

Article dans une revue avec comité de lectureARAUJO, Anna Carla; FROMENTIN, Guillaume (Springer Verlag, 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 ...
Communication avec acteARAUJO, 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, ...

Thence, this research work deals with an in-situ analysis of the ...
Article dans une revue avec comité de lectureFROMENTIN, 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 ...
