Effect of Temperature on Tool Wear During Milling of Ti64

Autor: Q. Lagarde, Vincent Wagner, Mahmoud Harzallah, Gilles Dessein

Publikováno v: Journal of Manufacturing Science and Engineering. 143

In recent years, the development of new, increasingly resistant materials limit machining productivity. This observation is especially true for titanium alloys. The state-of-the-art shows that one of the phenomena responsible for tool wear is tempera

Experimental and numerical investigations of the heating influence on the Ti5553 titanium alloy machinability

Autor: Mahmoud Harzallah, Maher Baili, Gilles Dessein, Daniel Lallement, Vincent Wagner

The use of titanium alloys has become more widespread in recent years. Regardless, although research work is enhancing, productivity levels remain low. Several alternatives have been considered and one of the techniques is envisaged is heating assist
