A tool assembly is provided with an integrated support fixture and assemblies for orienting the tool at different angles relative to a workpiece. A guide rail assembly is provided that defines a travel path for the tool slidably supported thereon. The support fixture is configured to support the tool assembly on a workpiece so that gravity can assist movement of the tool across the workpiece. The guide rail assembly is mounted on a miter plate that can be oriented at different miter angles relative to the support fixture. The tool may be supported on the guide rail assembly to permit pivoting of the tool perpendicular to the miter angle. Another assembly may be provided that permits pivoting of the guided rail assembly at an orthogonal angle.

A guidance assembly for circular saws includes a monobloc structural unit that incorporates a first, discontinuous annular subassembly and a second, flat inverted at 90 degrees U-shape elongated frame subassembly. A pair of angle beams is spacedly adjustable that is positionally adaptable to support various bases of circular saws. The guidance assembly further includes a fence subassembly, placed beneath the monobloc structural unit, with which is interconnected and cooperates. To prepare the cutting operation, the blade angle of a circular saw is matched to the required angle by rotating first and second subassemblies relatively to fence subassembly. For cutting, a wooden board is placed under first and second subassemblies, so that, laterally, is positioned against a first and a second hollow bars of fence subassembly.

Tools and methods are provided for scarfing rotor blade segments. A rotor blade segment includes a pressure side and a suction side. A tool includes a first guide configured for mounting on one of the pressure side or the suction side, the first guide including a first curved rail and a second curved rail spaced from the first curved rail. The tool further includes a second guide movably coupled to the first guide at a scarf angle, the second guide including a guide rail extending between and movable along the first curved rail and the second curved rail. The tool further includes a cutting device movably coupled to the second guide, the cutting device movable along the guide rail and operable to remove material from the one of the pressure side or the suction side.

An automated cross slide system having a cross slide with a back plate, a front plate and a saddle. The back plate can have a pair of end caps, a pair of linear guides, a first ball screw, a first gear box, a first servo motor, a first drive, and a first manual feed knob and the front plate can have a pair of end caps, a pair of linear guides, a second ball screw, a second gear box, a second servo motor, a second drive, and a second manual feed knob. The system can have a power supply, a communications hub with a processor and data storage connected to a network. The system can have a library of specification profiles and a human machine interface for accessing the library and controlling the first and second drives to cut a target piece in accordance with a selected specification profile.

A mobile machine tool for segmentally machining, in situ, a component, in particular a component of a turbine, which is rotatable about an axis of rotation. The machine tool has a main body, a support element which is held on the main body so as to be movable about a C-axis along a circular-arc-shaped guide path, and a tool module which is held on the support element and is designed to receive a tool. The tool module is located on the support element so as to be linearly movable. A method segmentally machines, in-situ, a component which is mounted in a stationary body so as to be rotatable about an axis of rotation.
