Cutting Edge Influence on Machining Titanium Alloy

  • Konrad Wegener
Reference work entry


The performance of machining titanium can be enhanced by using cutting tools with rounded cutting edges at adapted cutting speed and feed. The rounded cutting edges influence the active force components including plowing forces and tool face friction, which are especially important in machining titanium alloy as Ti–6Al–4V. Methods to correct determine the cutting edge radius is prerequisite for this analysis as well as methods to prepare cutting edge geometry in a controlled way.

The state of the art is mainly described in Wyen and Wegener (2010) as well as in Wyen et al. (2012).

Theory and Application


Titanium is classified as a difficult-to-machine material. Its mechanical and chemical properties cause high wear on cutting edges. By preparing cutting edges with defined rounding, initial crack formation can be reduced, the mechanical strength of a cutting edge can be improved, and the load on the cutting edge is changed. Different researchers proof an...
