A method and rivet apparatus to rivet a workpiece comprises an upper riveting portion and a lower riveting portion. The lower riveting portion comprising a fixed base, support member, and a pin assembly. The pin assembly comprises a center pin, a forming pin, a first biasing member, an outer shroud, and a second biasing member. The center pin pushes against a tail of a rivet to deform the tail of the rivet. The forming pin, fixedly coupled to the support member, pushes against the tail of the rivet to deform the tail of the rivet. The first biasing member, disposed below the center pin, biases the center pin through the forming pin and away from the support member. The outer shroud encircles the forming pin and the center pin. The second biasing member, disposed below the outer shroud, biases the outer shroud away from the support member.

A machine tool includes a first spindle, a second spindle, and a joining means for joining the axial ends of workpieces gripped by the spindles to form a joined workpiece. The machine tool further includes an electric servomotor for moving the first spindle in the direction intersecting the axis of the first spindle, a current value detection means for detecting the current value of the electric servomotor, and a misalignment detecting means for detecting misalignment of a first workpiece and a second workpiece in the joined workpiece, based on the current value detected by the current value detection means when the joined workpiece gripped by the two spindles is rotated.

A system and method for operating an angle stop having a first body, a second body, and a connector arrangement with a work component. The method includes placing the work component on a workpiece surface of a workpiece, contacting the first body having a first workpiece contact surface with a workpiece side surface of the workpiece, contacting the second body having a work component contact surface with the work component, fixing the work component to the second body, and fixing an angle between the first body and the second body.

In order to provide an operating method for a machine tool and to propose a system which enables the monitoring of the installation, position and the like of tools in a respective machine without the need for major construction work, the disclosure proposes a system for assigning tools mounted on rams to an installation position on a machine, which consists of a writable RFID chip with a transponder, memory and passive digital inputs positioned on the ram, and an electrically switchable contact panel positioned at a connection position of the machine, whereby the contacts of the contact panel can make contact with the digital inputs and the RFID chip transmits at least one identifier and the assignment of the digital inputs during a query process.

A servomotor (20) is driven to move a machine (10) with a ball screw (30). A first sensor (50) detects presence of the machine (10) at a first reference position (P) being predefined. A controller (60) stores a state of the servomotor (20) detected by an encoder (40) as reference state information upon detection of the machine (10) by the first sensor (50). The controller (60) estimates a position of the machine (10) based on the state of the servomotor (20) detected by the encoder (40) and the reference state information.

A three-dimensional target capable of serving as a positioning reference, including, on a useful face, a first structure and a second structure. The first structure defines a planar reference face divided up between at least a first portion whose surface is reflective according to a diffuse reflection, and a second portion whose surface is reflective according to a specular reflection, the second portion being divided up according to a series of localized zones positioned in the first portion. The second structure has an inclined face relative to the planar reference face. Applicable to three-dimensional optical measurement of the relative position between a first object and a second object.

Cutting a workpiece using a cutting tool associated with a system, whereby the system includes a guide having a first glyph and second glyph. The first and second glyphs are both visible on a single side of the guide. The guide is associated with a specific three-dimensional model of a plurality of three-dimensional models. The system further includes an input mechanism, configured to receive a location of the first glyph and of the second glyph, relative to the cutting tool. The system further includes a control system, functionally associated with the input mechanism and with the cutting tool. The control system is configured to direct the cutting tool to cut a version of the specific three-dimensional model into the workpiece at a location, such as at least partially between the locations of the first glyph and the second glyph, which locations were received by said input mechanism.
