out on a regular basis.” Unmanned titanium operations are not for ev- eryone, he cautioned. They require very predictable processes, and having different machines in an automated cell also helps. Another change in Ti machining is additive manufacturing (AM). “The most dramatic change in the last decade has been the introduction of AM,” said Greg Hyatt, senior vice president and chief technical offi cer at DMG Mori Advanced Solutions Inc., DMG Mori Seiki USA (Hoffman Estates, IL). “With AM, every Ti component can be deposited near-net.” As a result, high-torque is no longer required as rough milling is eliminated, leaving only fi nishing operations for conventional machines. Without high-torque spindles, the need for machine mass and rigidity is reduced.

A hybrid machining strategy is effective, according to Hyatt. “Our in-machine software for chatter reduction is even more effective with the fi nishing tools than for roughing, mak- ing this solution perfect for Ti machining in combination with AM,” Hyatt said. “Our ultrasonic-assisted milling solutions
