6 Problems with Wind Turbine Syndrome

6 Problems with Wind Turbine Syndrome

There are two massive problems with this lone remaining claim. First and most obviously is the easily measurable fact that wind turbines do not produce any significant infrasound; and second and only slightly less obvious is the fact that infrasound has never been shown to enhance the symptoms of life: headaches, insomnia, and so on.

Milling Process, Defects, Equipment

End milling - An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a complex surface contour.The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes.
