Machining of Difficult-to-Cut-Alloys Using Rotary Turning Tools

The importance and use of high temperature metals, such as titanium and nickel alloys, in aerospace industries have been continuously increasing due to their high strength-to-weight properties. These superior mechanical properties, however, reduce the machinability of these alloys. Rotary turning tools offer remedy to these problems. Rotary motion of the insert provides cool- down time outside of the cut resulting reduced cutting temperatures with longer tool life and higher productivity. In this article, rotary and stationary turning tools are compared in terms of tool life, cutting forces, surface and dimensional quality.
