MAG-IAS has produced an instructional video to demonstrate the combination of two innovative machining methods with traditional 5-axis machining, Modern Machine Shop (MMS) reports.
In the video, Mag’s NBV 700 5X achieves “blisk milling” of titanium via trochoidal milling, in which the tool moves in a curved tooling path in the shape of a trochoid. Additionally, cryogenic cooling is used, as liquid nitrogen is pumped along the tool (you can see this emerge as gas). Both techniques are used to preserve tool life.
MMS has more information about trochoidal milling here and more about cryogenic machining here.
