How Do Wind Turbines Survive Severe Storms? - Energy.gov

Every wind turbine has an anemometer that measures wind speed and a wind vane to keep track of the wind's direction. See if you can find them toward the end of the scene of this 360° Wind Turbine Tour video.. When the anemometer registers wind speeds higher than 55 mph (cut-out speed varies by turbine), it triggers the wind turbine to automatically shut off.

High Efficiency vs. High Feed Milling: Which is More

High-efficiency milling is based on the “radial chip thinning” theory that’s been around for a long time. The basic idea is to keep the tool cutting at an ideal chip load. To increase the metal removal rate, the stepover is substantially reduced from the typical 50% of tool diameter, but the feed rate is increased in order to maintain the correct chip thickness. Because the cutting force is reduced, you can mill with a much larger depth of cut with a solid end mill, plus get better utilization o

Jet mill - Wikipedia

A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size while continuing to mill particles above that size, resulting in a narrow size distribution of the resulting product.
