A machine integrated positioning system shows an operator where to place a raw part in the press brake or other machinery. Further, the operator is informed if the dimensions associated with the raw part are, or are not, correct to produce the planned finished part. The operator is visually shown how the raw part is to be oriented. The operator is informed if the raw part is right-side-up, along with other pre-final placement information. If these and other conditions are not met, the machine integrated positioning system may prevent the press brake and other machinery from cycling.

A chuck grip accuracy checking method includes a gripping in which the measurement target is gripped on the claws, a moving step, and a measuring step. In the moving step, a movable member provided with a measurement instrument capable of measuring a run-out of the measurement target is moved by driving a movable-member driver to a position at which the measurement instrument can measure a run-out of the measurement target. In the measuring step, a run-out of the measurement target is measured by the measurement instrument, while the chuck is being rotated by driving a rotation driver.

An imaging unit of a processing apparatus includes a microscope, and an imaging element connected to the microscope and including a plurality of pixels that capture an image. A control unit has a target pattern storage section that stores a target pattern for performing pattern matching, and a rectilinear region detection section that detects a rectilinear region on the basis of an image from the imaging element, calculates a deviation angle between a direction of the rectilinear region detected by the rectilinear region detection section and a processing feeding direction, and adjusts a relative angle between the target pattern stored in the target pattern storage section and a characteristic pattern on a wafer, to perform the pattern matching.

An apparatus for calibrating an air gap sensor of a machine tool can include a gauge block and a plurality of magnets. The gauge block can have a plurality of gauge grooves. Each of the gauge grooves can have a unique gauge depth that corresponds to a respective one of a plurality of predetermined calibration values for the air gap sensor. Each of the magnets can be embedded in the gauge block. A method of using the apparatus for calibrating an air gap sensor can include attaching the apparatus to a machine tool using only magnetic force to keep the apparatus in place.

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.

Provided is a misalignment determining device having a size thereof in an axial direction being made short. The misalignment determining device includes a case, a dial gauge, a holder portion, a support portion, a pivotal portion, a lever member, and a slide member. The slide member is placed in contact with a stylus of the dial gauge. While the pivotal portion and the lever member are rotated in synchronism with rotation of the holder portion, a pivot amount of the pivotal portion is transmitted to the slide member via the lever member, and based on an amount of movement of the slide member along an axis direction, the dial gauge determines the pivot amount.

A method of grinding or turning a workpiece, such as a bearing workpiece, involves several steps. One step includes locating the bearing workpiece on a chuck with an axis of rotation of the chuck positioned off-center relative to an axis of the bearing workpiece. Another step includes determining an offset between the chuck's axis of rotation and the bearing workpiece's axis based on the off-center position between the chuck's axis of rotation and the bearing workpiece's axis. Yet another step includes determining a path of engagement of a grinding wheel relative to the bearing workpiece based on the offset previously determined between the chuck's axis of rotation and the bearing workpiece's axis.

In a method for automated positioning of a blank in a processing machine provided with a housing and a spindle unit with an electric motor, a control unit for control and electrical supply of the processing machine, a computer producing processing programs for manufacturing workpieces, a workpiece holder, and an image recording unit that optically records image data of a blank received in the workpiece holder, a blank is fixed in the processing machine and the image recording unit produces an image of the blank. A division of the blank into an already processed region and into an unprocessed region based on the image data of the image is performed. A workpiece geometry to be produced is assigned to the unprocessed region of the blank, and a milling operation is performed on the unprocessed region. In a variant of the method, the image recording unit is separate from the processing unit.
