摘要： 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.

As the welding arc struck between the electrode (22) and the workpiece (16) is oscillated laterally (14) within the groove means (28 and 30) are provided for supplying an indication of both the voltage drop between the electrode and the side wall of the groove as the arc approaches the side wall, and the width of the excursion of the arc from the center of oscillation to the point where the voltage is measured. The center of oscillation is then adjusted as a function of the measured width and voltage.

摘要： Method and apparatus for welding edge joints such as turbine blades and the like, including adaptive tracking circuitry for maintaining the center of oscillation of the welding electrode substantially aligned with the center of the workpiece as the electrode is moved along the workpiece, and means for adjusting welding parameters such as welding current to prevent melt over of the edge and wirefeed rate to control overlay height as the welding electrode approaches to within a predetermined distance from the edge of the workpiece. The disclosed embodiment samples the arc signal, processes the arc signal to remove undesirable noise components, uses the processed signal to adaptively position the electrode with respect to the workpiece, and controls the welding parameters related to overlay height when the sensed position of the electrode reaches a predetermined distance from the edge of the workpiece.

摘要： Apparatus and method for sensing the topography of a workpiece with an electrical arc by measuring a parameter of the electrical arc signal as an electrode is scanned across the surface of the workpiece by a tool manipulator such as a multi-axis robot arm, and processing the measured arc signal in order to derive the three-dimensional topography. The apparatus includes a digital microcomputer which samples the arc signal, stores a plurality of samples in computer memory, computes the average of a predetermined number of samples, and provides correction factors to the host computer of the robot manipulator so that the electrode or a tool carried by the robot can be adaptively positioned. The apparatus senses such features of the workpiece as holes, edges, and slopes of a given magnitude, and passes the location of these features to the host computer for appropriate corrective action. The system provides vertical correction factors as well as workpiece scanning correction factors so that the host can adaptively adjust the position of the electrode or of a separate tool with respect to the workpiece.

摘要： Apparatus for rapid and automatic welding of joints which interconnect sections of pipe, and in particular oil or gas transmission pipe. The system includes at least one torch transport assembly which simultaneously moves a plural number of welding torches along a path parallel to the pipe joint being welded. The torch transport assembly includes track segments which surround circumferential portions of the pipe joint, with a welding torch carrier and multiple torches being independently movable along each track segment. The torch transport assembly is mounted on a support apparatus which is rigidly clamped to the pipe sections during welding, and which permits the torch transport assembly to be rapidly positioned in rough alignment with a pipe joint. The torch transport assembly and selected operating parameters of each welding torch are adjusted to accurately position each torch with respect to the pipe joint, and to repeatably provide programmed welding parameters resulting in a uniform pipe joint weld. The present system is disclosed in the context of hot-wire gas-tungsten arc welding torches, and in the operating environment of out-of-position joint welding.

摘要： A swirler is provided for mixing air from a compressor and fuel from a fuel injector for discharge into a dome of a gas turbine engine combustor. The swirler includes a tubular ferrule for coaxially receiving the fuel injector. A plurality of circumferentially spaced apart swirl vanes are fixedly joined coaxially with the ferrule. An outlet tube is fixedly joined coaxially with the swirl vanes in flow communication therewith for receiving air from the swirlers and fuel from the fuel injector. An annular collar is fixedly joined around the outlet tube and has a convex spherical outer surface. An annular mounting flange for mounting the swirler to the combustor dome has a concave spherical inner surface disposed coaxially around the collar outer surface in a sliding fit therewith to define a ball joint for allowing relative rotation therebetween for self-aligning the fuel injector with the swirler.
