A device for supporting and/or guiding a machine tool or a workpiece, wherein the device includes a contact body having a contact surface for contact on a work surface of a workpiece or a wall. It is provided that the contact body includes a holding element having an adhesive means for adhesion to the work surface, wherein the adhesive means, when the contact surface of the contact body bears against the work surface, can be brought from a positioning state, in which the adhesive means is not in contact with the work surface and the contact surface can be positioned with respect to the work surface into an adhesive state, in which the adhesive means adheres to the work surface and fixes the contact body on the work surface.

A holding element for a device for supporting and/or guiding a machine tool or a workpiece, wherein the device includes a contact body having a contact surface for contact on a work surface of a workpiece or a wall. It is provided that the holding element includes an adhesive means for adhesion to the work surface and a fastening means for a releasable hold on the contact body, wherein the fastening means includes at least one formfitting contour for formfitting hold on a holding element receptacle of the contact body.

A routing jig for enabling location of router guides prior to routing a feature into a workpiece includes a transparent or semi-transparent base component having longitudinal sides, a lower surface and an upper surface. The routing jig also includes retaining structure such as side bars and screws. The base component and the retaining structure together define a nominal width of the routing jig in a transverse direction. A plurality of shims are selectively and removably securable to the longitudinal sides of the base component by the retaining structure, thereby to increase the nominal width of the routing jig.

The invention discloses a system for hole making for an aircraft skin by normal positioning and locking. The hole-making system includes a posture adjustment part, a normal positioning and locking part and a hole-making execution part. This system solves the problems that the device in the prior art has high complexity and cumbersome positioning and does not adapt to complex curved surfaces, thereby failing to satisfy the needs of efficient hole making in different space states. In the present invention, the expansion of an outer expansion sleeve in a bottom sleeve locks a normal direction for hole making, thereby ensuring the positioning accuracy of the normal direction. An axial position is locked by the mutual cooperation of an axial positioning groove of the bottom sleeve and an axial positioning rib of the outer expansion sleeve. A hole-making auxiliary cylinder contracts to counteract part of an axial force for hole making.

A system and method for constructing a composite structure using a multi-piece tool. The pieces are assembled, including making a connection, such as a mortise-and-tenon connection, between pieces using an adhesive mixed with an induction heatable material, such as iron filings having a unit size of between 5 microns and 600 microns, and an amount of between 5% and 50% by volume. Plies of a material are applied around the connection between the pieces, and the plies are cured to create the composite structure, which results in the pieces being trapped within the composite structure by the connection. The adhesive is exposed to electromagnetic induction from an electromagnetic induction coil which generates heat in the induction heatable material and thereby loosens the connection. The tool can then be disassembled by individually pulling at least some of the pieces from within the composite structure.

In one or more arrangements, a stationary cross cut system includes a base having an upper surface configured to receive a workpiece during a cutting operation. The system also includes first and second extendable support wings connected to the base. When extended, the first support wing supports a workpiece that extends past the first side of the base and the second support supports a workpiece that extends past the second side of the base. In some arrangements, the base includes first and second fences and is configured to receive the workpiece between the first and second fences. In some arrangements, the system also includes a first rail extending between the first fence and the second fence and a second rail extending between the first fence and the second fence. The first rail and second rail are configured to receive and guide a cutting tool during the cutting operation.

Provided is a machining device for machining a rotor arranged in a turbine housing which includes two parts, thereby forming a joint, in situ while the upper housing half is removed. The machining device includes a main part that releasably secures the main part to the lower housing half in the region of the joint, at least one tool holder for receiving at least one machining tool which is secured on the main part directly or indirectly so as to be alignable relative to the main part, multiple telescopic stabilizing elements which can be locked into different longitudinal settings preferably in a continuous manner.

A straight edge guide system is presented that makes clamping of a workpiece faster and easier. The straight edge guide system includes a guide member that extends a length from a first end to a second end. A clamp member is connected to the first end of the guide member and includes a compressible bias member therein. An adjustable stop member is connected to the guide member that moves between a locked position and a free position. When the adjustable stop member is in the free position, the adjustable stop member slides along the length of the guide member. When the straight edge guide system is placed on top of a workpiece, the workpiece is clamped under spring bias force between the clamp member and the stop member.

A portable cross cut system is presented that includes a main body having a reference edge configured to be aligned against an edge of a workpiece and an engagement member configured to be laid on top of the workpiece. A first guide edge extends along an outward edge of the main body and the engagement member and is configured to guide an edge of a baseplate of a cutting tool during a cutting operation. The main body includes a blade offset member having an arm that moves between an extended position and a retracted position. When the arm is extended the outward end of the arm indicates the position of a cut line so that the user can easily align the position of the portable cross cut system to easily and accurately make cuts in a workpiece.
