A robotic apparatus and system for cutting turbine bucket covers on a turbine rotor are provided. The robotic apparatus includes a grinding device operable to drive a grinding wheel, a robotic arm coupled to the grinding device, a base member coupled to the robotic arm, a vision system for locating the fastener on the turbine bucket cover, and a control system. The base member is mounted independently of the turbine bucket cover. The control system is coupled to the vision system, the grinding device, and the robotic apparatus, and configured to control movement of the robotic apparatus and the grinding device based upon vision system data and spatial information related to the turbine bucket cover. The system includes at least a portion of a turbine rotor including a turbine bucket cover having at least one fastener thereon, and a robotic device for cutting the turbine bucket cover.

Embodiments of the invention are directed to a portable grinding apparatus comprising: a frame; a boring bar operatively coupled to the frame; and a grinding assembly operatively coupled to the boring bar, wherein the grinding assembly is adjustable in one or more axes by adjusting the frame or the grinding assembly for grinding a component secured to the frame.
摘要:
A method and apparatus for sanding a number of surface features on a surface of an object. A first type of operation may be performed on the number of surface features on the surface of the object using a first end effector. Feedback laser data may be generated about the number of surface features after the first type of operation has been performed using a laser device. A second type of operation may be performed on the number of surface features using a second end effector and the feedback laser data to rework the number of surface features until the number of surface features has been reworked to within selected tolerances.

A tool for in-situ airfoil contouring is provided. The tool has a pathway for an airfoil edge wherein the edge movement is limited and further wherein the edge is exposed to a grinding structure having a preselected profile shape therein. The tool makes this contouring process available for airfoils without the necessity of removing the airfoils from, for example, an aircraft engine.

For shaping the leading edge (1) of blisk blades (2), the shape, amount and disposition of the material to be removed in a subsequent grinding and polishing process is determined beforehand over the entire blade length. The blade leading edge is milled such that an elliptical profile (3) has a material allowance (7) which over the length of the leading edge exactly corresponds to an expected material removal during the grinding and polishing process, so that a blisk blade is produced whose leading edge features an aerodynamically advantageous shape.

The invention relates to a method and an arrangement for re-creation of an optimized contour of the leading edges of gas-turbine blades, in which a gas-turbine blade (2) is passed by one or more grinding machine or machines (71, 71′) with the aid of a computer-controlled robot (10). The desired contour is achieved by following a movement procedure which is stored in a data memory (21). The stored movement procedure is designed to convert a blade from a previously determined statistical mean wear state to a likewise previously determined or calculated design contour. The contact pressure of the gas-turbine blade on the grinding disk or disks (71, 71′) is measured and is taken into account in the movement procedure of the robot (10) such that the desired design contour is achieved irrespective of the initial contour and wear of the grinding disks.
摘要:
A method of post processing a laser peened component to remove a laser remelt layer is proposed. The post processing includes a series of steps including grit blasting, chemical etching and mechanical finishing the component. This will ensure that the mechanical property (i.e., damage tolerance) benefit of laser peening is restored to the surface of the component.
摘要:
A method is provided for determining the diameter of a rotor of a turbomachine, rotor being equipped with rotor blades. The method involves setting the rotor with the rotor blade ring in rotation, arranging a clearance measuring device assigned to the rotor blade ring outside the region of the latter, measuring the distance to the rotor blades of the rotor blade ring which are rotating past the clearance measuring device, and using the measured distance for determining the diameter of the rotor. During measuring, the rotational speed is identical to, almost identical to or higher than the setpoint rotational speed of the rotor.
