"&lt;p&gt;Holes in turbine blades are critical because the internal cooling airflow provided by these holes prevents the parts from overheating during operation. One of the most promising technologies for making these holes is fast-hole electrical discharge machining (EDM).&lt;/p&gt;&lt;p&gt;\u00A0&lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
