Abstract

The present invention is for a method of machining elongated workpieces (10), such as, for example, helicopter rotor blades and other aircraft spars, on a machine (20) such as a machining center, utilizing an ultrasonic gauge to prepare a “virtual” model of the workpiece (10) and to adjust positioning of the workpiece (10) relative to the machine automatedly so as to result in a finished workpiece (10) having negligible variations in the wall thickness thereof, i.e., an approximately constant wall thickness.
