A test device and method for testing one of a disk drive microactuator and a disk drive sensor that includes two piezoelectric elements. The test device includes a signal generator, signal analyzer, and a user interface. The test device is operational to provide a reference signal (e.g. an electrical signal) to one of the piezoelectric elements in the microactuator and obtain a test measure from the other one of the piezoelectric elements. The test measure is then utilized to assess a performance parameter for the microactuator. The test measure is generated by the other one of the piezoelectric elements in response to the reference signal provided to the first one of the piezoelectric elements. In one embodiment of the invention, the test measure is a signal generated in response to the reference signal that may be compared to a known response signal of an operational microactuator to determine operational characteristics of a subject microactuator such as circuitry operation and / or damage to the microactuator.

The present invention relates to a system and method for automated or “robotic” application of hardfacing to the surface of a steel-toothed cutter of a standard earth-boring rock bit or a hybrid-type rock bit. In particular, the system incorporates a grounded adapter plate and chuck mounted to a robotic arm for grasping and manipulating a rock bit cutter, particularly a hybrid rock bit cutter, beneath an electrical or photonic energy welding source, such as a plasma arc welding torch manipulated by a positioner. In this configuration, the torch is positioned substantially vertically and oscillated along a horizontal axis as the cutter is manipulated relative along a target path for the distribution of hardfacing. Moving the cutter beneath the torch allows more areas of more teeth to be overlayed, and allows superior placement for operational feedback, such as automatic positioning and parameter correction. In the preferred embodiment, sensors provide data to the control system for identification, positioning, welding program selection, and welding program correction. The control system, aided by data from the sensors, manipulates the robotically held cutter while controlling the operation and oscillation of the torch. These systems and methods can be applied to hardfacing steel teeth of the rolling cutters of both standard tri-cone or di-cone type rolling cone bits, as well as to hybrid-type earth boring drill bits.
