Video: High Feed Milling in Aluminum
Footage shows roughing at 48 cubic inch per minute on a standard-speed machining center.
This video shot by Boeing St. Louis shows a 4-flute, 2-inch-diameter high feed mill from Iscar machining aluminum at 0.080 axial depth of cut and 300 ipm for a metal removal rate of 48 cubic inches per minute. Boeing often recommends the use of high feed milling as part of a strategy for making efficient use of lower-rpm machining centers. For more, see the article under “Editor Picks” at right.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
Part of a series of articles on more efficient machining of pockets in titanium parts, this article makes the case for a tool with many cutting edges, and describes how best to apply it.
What’s it going to cost? How much space do I need? What environmental hassles will I encounter? How steep is the learning curve? Exactly what is anodizing? Here are answers to preliminary questions shops have about bringing anodizing in-house.
