Patent number: 8191753Abstract: An apparatus and computer program are disclosed for processing at least one workpiece using a rotary tool with rotating member for contacting and processing the workpiece. The methods include oscillating the rotary tool laterally with respect to a selected propagation path for the rotating member with respect to the workpiece to define an oscillation path for the rotating member. The methods further include obtaining force signals or parameters related to the force experienced by the rotary tool at least while the rotating member is disposed at the extremes of the oscillation. The force signals or parameters associated with the extremes can then be analyzed to determine a lateral position of the selected path with respect to a target path and a lateral offset value can be determined based on the lateral position. The lateral distance between the selected path and the target path can be decreased based on the lateral offset value.Type: GrantFiled: October 7, 2011Date of Patent: June 5, 2012Assignee: Vanderbilt UniversityInventors: Paul Fleming, David H. Lammlein, George E. Cook, Don Mitchell Wilkes, Alvin M. Strauss, David R. Delapp, Daniel A. Hartman

Patent number: 7850057Abstract: A friction stir system for processing at least a first workpiece includes a spindle actuator coupled to a rotary tool comprising a rotating member for contacting and processing the first workpiece. A detection system is provided for obtaining information related to a lateral alignment of the rotating member. The detection system comprises at least one sensor for measuring a force experienced by the rotary tool or a parameter related to the force experienced by the rotary tool during processing, wherein the sensor provides sensor signals. A signal processing system is coupled to receive and analyze the sensor signals and determine a lateral alignment of the rotating member relative to a selected lateral position, a selected path, or a direction to decrease a lateral distance relative to the selected lateral position or selected path.Type: GrantFiled: February 11, 2010Date of Patent: December 14, 2010Assignee: Vanderbilt UniversityInventors: Paul Fleming, David Lammlein, George E.

Patent number: 5823906Abstract: A nutation motion generator which transforms linear motion into nutation motion. The device employs a spherical, four-bar linkage mechanism. Three four-bar linkage mechanisms are sandwiched between a stationary support surface and a drive plate and arranged at 120.degree. intervals about the support surface. Each four-bar linkage mechanism is constructed of four planar sections which are hinged along their edges, the four hinged planar sections being essentially triangular in shape so that they would join at a point in the center of the device if they extended to the apex of their respective triangles. A universal joint is located at the center of the device to provide stability. The four-bar linkage mechanism can be collapsed to a substantially flatten configuration, opened and then collapsed to a substantially flattened configuration at an angle 90.degree. to that of the first flattened configuration.Type: GrantFiled: January 2, 1997Date of Patent: October 20, 1998Assignee: Vanderbilt UniversityInventors: James D. Ashburn, Steven W. Peterson, Alvin M. Strauss
