A machining apparatus includes encoders that detect first rotational positions of motors that respectively drive an unwind shaft and a take-up shaft for conveying a material, an encoder that detects a second rotational position of a motor that drives a cutter edge for cutting the material, and a controller that controls the motor based on the first rotational position and controls the motor based on the second rotational position to coordinately control conveyance of the material and movement of the cutter edge. The controller calculates positional relationship information representing a positional relationship between the material and the cutter edge based on the second rotational position, determines whether the cutter edge is in contact with the material based on the positional relationship information, and estimates a life of the cutter edge based on a load on the motor when the tool is in a contact state.

Provided is a rotational positioning device capable of positioning a rotational angle at a target angle position with high precision. A rotational positioning device is provided with: a housing; a rotational member which is rotatable about a rotational member axial line and at least a part of which is accommodated in the housing; and at least one sensor installed in the housing. A graduated scale with a plurality of scale marks is formed integrally with the rotational member along the circumferential direction of the rotational member. The at least one sensor detects an angle change amount due to rotation of the rotational member on the basis of the plurality of scale marks. The rotational member is positioned at the target angle position on the basis of the angle change amount.

In a device for recording deformation of a rotor head of a work spindle, at least one magnet is arranged on a stator or a rotor of the spindle, the magnetic field of which penetrates a measurement section of the rotor head, which is traversed by an axial flow of force during clamping of a tool or tool carrier on the rotor head by a tool clamping device arranged in the rotor. The rotor head has a magnetizability or magnetization that varies in the axial direction in its measurement section, and at least one direction-sensitive magnetic field sensor is arranged on the stator radially opposite the measurement section, which is connected to an evaluation device to determine axial deformation of the rotor head as a function of rotation angle from the strength of the magnetic field as a function of rotation angle recorded by the sensor during one revolution of the rotor.

An advanced jig for manufacturing a firearm lower receiver can include an adapter, a guide plate, a front support, a buffer support, a buffer mounting screw and at least one carriage with at least one locating pin. A guide plate can be in a location above the fire control cavity of a lower receiver and can be mounted to the carriage(s) in conjunction with a rotary power tool adapter. The jig can be a universal fitment. The jig can include a bearing to support a rotary tool and can be constructed and arranged to provide for use of at least one guiding feature to facilitate in the guidance of the rotary tool without placing the rotary tool in direct contact with any of a plurality of guidance features for firearm lower receiver manufacturing. A removable locating pin can be situated in a location along the front takedown pin hole of a firearm receiver that is for firearm lower receiver manufacturing.

A multifunction spindle for a machine tool for machining workpieces has a spindle housing, rotational drive, and tool-holding unit. The tool-holding unit is disposed within the spindle housing and pivots relative to the spindle housing about an axis perpendicular to the axis of rotation. The spindle has two measurement heads connected to a transmission path for measuring position angle and enhances positioning accuracy.

A method for manufacturing panels such that the panels are subjected on at least one side to an operation with cutting tools. The position and/or orientation of each panel is determined prior to the operation, and the position and/or orientation of each panel is adjusted prior to the operation and/or the position of the tools is potentially adjusted, such that at least one part of each panel concerned takes a fixed orientation and position in relation to the tools.

A work centre to process section bars, in particular made of aluminium, light alloys, PVC or the like, is provided with a plurality of gripping units movable along a base and designed to hold at least one section bar, an overhead crane movable along the base and provided with at least one operating head to cut and/or process sections bars, a signalling unit provided with a plurality of light devices distributed along the base, and an electronic control unit configured to selectively turn on the light devices and signal to the operators in charge the position of each section bar to be loaded in the relevant gripping units.
