Process Innovations: Machining Techniques for Difficult Titanium Alloys

Chicago, Illinois - The materials landscape is ever changing. There is a constant pursuit to reduce weight, increase safety, achieve high temperature performance and improve fuel economy. This has driven the development of complicated and difficult-to-machine materials, including ceramics, composites, advanced superalloys, burn-resistant titanium alloys and powder metallurgical alloys. Today’s manufacturers are challenged with machining them with a level of cost effectiveness that makes their use viable.

This presentation will provide a brief overview of some of the newest materials today’s manufacturers may encounter. It will detail the latest developments related to effective machining of them, including discussion of laser-assisted machining, unique tool geometries, new tool coatings and processes such as trochoidal milling and dynamic milling.
