In recent years, titanium has become dramatically more significant as a workpiece material in machine shops. Two industries are driving this. One is aerospace. The latest aircraft designs use dramatically more titanium than planes of the past. The other is the medical industry. Titanium is a common material used for implants and devices used within the body. Titanium’s high hardness and low thermal conductivity make it more challenging to machine than other metals that most machine shops are more accustomed to facing.
Choose cutters, depths and tool paths with attention to particular steps in the process, and you can machine titanium more efficiently than you might suspect. Boeing offers practical tips.

Laser sintering is an additive process that deposited metals, such as Titanium, to create complex machinable workpiece blanks.
Rather than start with the machine, says Boeing, start with the tooling. For titanium workpieces and other high-value parts, a simple spreadsheet of tools and operations might be the most valuable resource for machining center selection.
Boeing’s answer to a reader question emphasizes the use of high-feed milling tools.
