Composites Machining for the F-35
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.

What Don’t you Like About that Canned Cycle?
Almost all CNC users take advantage of control-based canned cycles. Even CAM systems commonly output G-code programs that contain canned cycle commands. This includes hole machining canned cycles, such as drilling, tapping, boring and more, and whatever milling cycles the machine may have. For turning centers, it includes roughing and finishing multiple repetitive cycles.
