A fixture and a method of operating the fixture are disclosed for repositioning a workpiece disposed on the fixture to correct an offset between the centerline of the workpiece and an indexing position on the fixture. The fixture includes one or more linear actuators that linearly move vacuum grippers on their outboard ends into contact with surfaces of the workpiece. Vacuum is applied to the vacuum grippers, which enables the vacuum grippers to grip the surfaces of the workpiece. The linear actuators are driven to reposition the workpiece on the fixture to reduce the offset between the two below a threshold value. When in position, the fixture secures the workpiece in place for subsequent machining operations that may be performed on the workpiece.

A device system with a device stand, a drilling device arranged displaceably on the device stand for carrying out drilling and a feed device for displacing the core drilling device along the device stand. The feed device has a manual feed device, designed for example as a handwheel or a lever, and the device system has a control device for evaluating measured values. The feed device or the manual feed device e has a sensor for determining measured values, the measured values being used for evaluation and transmitted to the control device, and a starting point and/or an end point of the drilling being detected by the control device through a sudden change in drilling parameters. In a second aspect, the invention relates to a method for determining a depth of a bore, the bore being produced with the proposed device system.

There is provided a processing apparatus including a holding table having a holding surface for holding thereon a workpiece with a plurality of devices formed in respective areas demarcated on a face side of the workpiece by a plurality of projected dicing lines, a processing unit that processes the workpiece held on the holding table, an image capturing unit that captures an image of the workpiece held on the holding table, a moving unit that moves the holding table relatively to the processing unit and the image capturing unit in horizontal directions along the holding surface, a touch panel that displays thereon the image captured by the image capturing unit, and a control unit. The control unit detects a line in an image positioned within an allowable region based on a contact line traced on the image displayed on the touch panel and registers the detected line.

A device for determining an approach of a tool to a workpiece in a machine tool with internal cooling supply includes a measuring arrangement, having a measuring graduation arranged in a rotationally fixed manner on a shaft and at least one position sensor arranged in a fixed manner relative to the shaft, and a data processor. The position sensor is adapted to scan the measuring graduation and to generate position values therefrom that indicate a position of the shaft. The position values are fed to the data processor, which, by evaluating a progression of the position values when the tool approaches the workpiece, determines that the tool is located in an approach area relative to the workpiece, and signals, by an approach signal, when the tool reaches an approach position relative to the workpiece, in which the tool is close to the workpiece without touching it.
