An on-car brake lathe is provided with a runout compensation system configured to monitor the rotational position of a pair of slant discs within an aligning joint of the on-car brake lathe. The system monitors the amount of runout present between the rotating components of the on-car brake lathe and the wheel hub to which the on-car brake lathe is secured. The system calculates the appropriate rotational position for each slant disc within the aligning joint required to impart a necessary adjustment in the wheel coupling rotational axis in order to align the on-car brake lathe with the rotational axis of the wheel hub. Finally, an adjustment mechanism is activated to rotationally drive each slant disc directly to the calculated rotational position with a minimum amount of rotational movement based on the current rotational position of each slant disc and the required calculated rotational positions.

A component production method includes: a step of binding a long frame by a plurality of support devices arranged along the frame; a step of measuring, with a distance sensor, a distance to the frame supported by the plurality of support devices; a step in which, based on frame shape data prerecorded in a memory, the support devices move support positions where the frame is supported so that a calculated radial position of the frame being supported by the support devices matches the data about the frame shape; a step of fixing the frame in a state in which the data about the frame shape matches the radial position of the frame; and a step of performing a hole-making operation on the fixed frame.

The disclosure relates to a clamping apparatus for fixing in a recess of a component and for holding a workpiece carrier against the component. The clamping apparatus includes a housing for attachment to the workpiece carrier and a clamping sleeve for insertion into the recess. A clamping mandrel is at least partially disposed inside the clamping sleeve. The clamping mandrel is movable relative to the clamping sleeve between a release position and a clamp position. When the clamping sleeve is inserted into the recess and the clamping mandrel is in the clamp position, the clamping sleeve is braced within the recess by a holding force so as to be in a clamped position. When the clamping sleeve is in the clamped position, the housing is movable relative to the clamping mandrel, which permits the housing to move the workpiece carrier into contact with the component and apply a bearing force thereagainst.

Provided are a machining method and a machining device that can reduce the displacement from a target round shape due to elastic deformation after machining, and can shorten the time required to machine a target round shape in the work. A machining method machines a round hole in a work, and includes: a hole-shape acquisition step of acquiring a shape of a hole of the work; an inverted-shape acquisition step of inverting the shape of the hole acquired at the hole-shape acquisition step relative to a target round shape to acquire an inverted shape; and an inverted-shape machining step of machining the hole in accordance with the inverted shape acquired at the inverted-shape acquisition step.

The drill bit straightening system described herein may include a drill bit holding assembly configured to hold a drill bit, one or more sensors configured to measure edge eccentricity of a shaft associated with the drill bit, a control unit configured to automatically control a straightening operation of the drill bit straightening system, and a drill bit pressing arm configured to straighten the drill bit by applying a force calculated based on one or more predictive models. The control unit may be configured to calculate force(s) to be applied to the drill bit using one or more predictive models.

The present invention provides a method for locating a machining position in a repair material that is arranged on a member including a machined portion formed by predetermined machining, the method including: a step of arranging a marker including a portion having a different propagation characteristic of an ultrasonic wave from that of a peripheral portion in the machined portion existing in the member before the repair material is arranged on the member; and a step of applying the ultrasonic wave to the member covered with the repair material and locating the machining position at a position of the marker captured by the ultrasonic wave after the repair material is arranged on the member.

Systems and methods for lathe and tooling calibration are disclosed. A sensor is utilized to measure dimensions and operational parameters of one or more components of a lathe, such as a turret, tool stations, and/or a spindle. Tool measurements are received and analyzed along with the measurements from the sensor. The dimensions and operational parameters may be utilized to calibrate movement parameters of one or more components of the lathe. Once calibrated, the lathe may be utilized to tool one or more objects.

A manufacturing method is provided. During this method, a panel is provided that includes non-conductive material and a plurality of conductive elements at least partially embedded within the non-conductive material. The conductive elements include a first conductive element. An electric current is applied to the first conductive element such that the first conductive element produces a signature. A location of the first conductive element in the panel is determined based on the signature. An aperture is formed in the panel based on the determined location of the first conductive element.

An apparatus that includes a tool head; an insert that is coupled to the head and configured to engage an inner diameter of a workpiece, so as to machine the workpiece; a boring bar or drill tube coupled to the head, the boring bar or drill tube configured to extend through a guide bore in the workpiece; and a measuring device that is positioned proximate to the head and configured to measure a radial dimension, an axial dimension, or both of the inner diameter. The head may include a plurality of inserts, wherein the plurality of inserts are selectable such that the inserts are engageable with the inner diameter of the workpiece. The measuring device may include a contact-based measuring device.

A method for operating a machine tool that includes an electric motor for driving a drilling tool and an open- and closed-loop controller for open- and closed loop control of the motor power. The method includes: operating the machine tool in a tapping mode at a first rotational speed value, where the first rotational speed value is lower than a predetermined idling speed value of the electric motor; detecting a predetermined first threshold value for the motor current; reducing the motor current to a predetermined second threshold value when the first threshold value is exceeded; operating the machine tool at a second rotational speed value, where the second rotational speed value is lower than the first rotational speed value; operating the electric motor at a predetermined motor current value; and operating the controller for closed loop control of the motor power via the motor current with an oscillating action.
