A method of manufacturing a component is provided. The method includes performing a machining operation by moving a rotating, abrasive grinding tool along a feed direction to remove material from the component. At least the part of the component from which the material is removed is formed of composite material. The abrasive grinding tool follows a trochoidal path along the feed direction.

A finishing tool for modifying a surface of a part, including: a base, wherein the base is one or more of rotated and translated; and one or more fibers coupled to the base; wherein a base portion of each of the one or more fibers is disposed at a first angle relative to a major axis of the base, wherein the first angle is equal to or between 90 degrees and 90 degrees; and wherein, in operation, an end portion of each of the one or more fibers is disposed at a second angle relative to the major axis of the base, wherein the second angle is approximately 90 degrees or 90 degrees, substantially parallel to the surface of the part. In operation, the base portion and the end portion of each of the one or more fibers is coupled by a continuously curved intermediate portion.

The invention relates to a grinding tool for grinding a leading edge of a wind turbine blade. It comprises two parallel shafts of which at least one is rotationally driven and a frame for holding the two shafts in a fixed mutual relationship. An annular abrasive belt is arranged around a tension device mounted to the frame and guides of which there is one on each of the two shafts. The abrasive belt runs in a plane perpendicular to the shafts and has a longer length than an imaginary curve formed by outer surfaces of the tension device and of the guides. The grinding tool further comprises two abrasive belt retainers movably mounted to the frame. They are shaped and arranged to move between a retaining position in which they retain the abrasive belt along at least parts of the abrasive belt which is in contact with the guides, and a release position in which they are out of contact with the abrasive belt.

This disclosure relates to a tool guide for a tool that shapes a workpiece. The tool guide may include a body having a contact surface configured to contact a surface of a workpiece, a tool holder positioned within the body and configured to hold a machining tool having a tool bit, the tool holder holding the machining tool in a predetermined orientation relative to the workpiece, a guide element attached to the body configured to engage a surface feature of the workpiece, and an upper opening and a lower opening in the body configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece.

A grinding robot for grinding an electrically conducting workpiece. The grinding robot includes a grinding wheel, an actuation device for actuating grinding wheel, and a control system. The grinding wheel including an undulated tool receptacle which defines an axis of rotation about which the grinding wheel can rotate during grinding, and a head which is rotationally symmetrical with respect to the axis of rotation, and which contains abrasive material and has a grinding surface which is in contact with workpiece during grinding. The grinding wheel also includes a measuring and transmission unit and at least one conductor strand pair with two conductor strands which are electrically insulated from one another. The conductor strands are embedded in the rotationally symmetrical head and extend from the grinding surface of the head into the interior of the head and are electrically connected with measuring and transmission unit.

A system provides in-situ surface processing of an engine blade within an aircraft engine. The system includes an endoscopic processing instrument with a variable-angle tubular shaft. The processing instrument is inserted radially through a lateral access opening into the aircraft engine in a non-angled initial configuration. The lateral access opening is downstream of the engine blade. The processing instrument has a rotatably driven tool holder at a distal end of the shaft for a surface processing tool head. In an angled working configuration, a tool head inserted into the tool holder is applied to a flow edge of the engine blade. Furthermore, a process uses the corresponding system.
