A method and an apparatus for detecting and correcting a spatial position of a workpiece held in a positioning device, wherein a machining head having at least one sensor and position sensor is fed into at least one measuring position. Contactless sensing of an actual position of a measuring point of the workpiece is carried out at the measuring position using the machining head and the sensed actual position is compared with an expected nominal position and deviation values between the actual position and the nominal position are ascertained. The ascertained deviation values are compared with an admissible tolerance value and the machining head is fed to a contour when the ascertained deviation is within the admissible tolerance value, or the machining head and the workpiece are oriented with respect to one another and to the contour such that a deviation of the actual position is within the admissible tolerance values following orientation.

Provided is a clamp system with enhanced functionality achieved by detecting the behavior of an object to be clamped, using a stroke-end position detector that has been used for switching stroke operations. A clamp device 1 has an output member 12 which executes a stroke movement causing a change in the distance by which a coil 15 is inserted into a hole 14 having a bottom. A converter 23 outputs a measurement value of the inductance of the coil 15. The inductance of the coil 15 when a work W has been clamped by the output member 12 is stored in a work clamp point memory 22e, and a clamp area indicating a variation range permitted with respect to a work clamp point is set in a clamp area memory. During processing of the work, a control unit 2 measures the inductance of the coil 15, determines whether the work clamp point is within the range of the clamp area, and, if the range is exceeded, issues a signal indicating an emergency stop.

A measuring apparatus for measuring a planar relative motion between a tool attacher and a work attacher of a machine tool includes at least one image capturing element capable of performing image capturing at a first position, a second position, and a third position, which are not located on the same line. The image capturing elements at the first position, the second position, and the third position are caused to capture a first point, a second point, and a third point, respectively, arranged on at least one plane of an XY-plane, an XZ-plane, and a YZ-plane. The image capturing element at the second position and the image capturing element at the third position are caused to capture the first point, the image capturing element at the first position and the image capturing element at the third position are caused to capture the second point, and the image capturing element at the first position and the image capturing element at the second position are caused to capture the third point. Based on the image capturing result, a value indicating the planar relative motion between the tool attacher and the work attacher is calculated.

A machine tool includes a frame with two opposite frame sections, a number of leg elements arranged on the frame, and a first carriage having a first linear axis. The first carriage is guided on the two opposite sections of the frame and is displaceable in a first direction. A second carriage of a second linear axis is guided on the first carriage and is displaceable in a second direction A tower element has a third linear axis, which is retained on the second carriage. A machining element is retained on the tower element and is displaceable in a third direction, and a tool spindle is arranged on the machining element for receiving a tool.

The present disclosure is directed to calibrating position detection for a tool. The tool can use a sensor to detect a first value of a parameter. The tool can use a motor to extend the working member of the tool towards a working surface. The tool can include a base.

The tool can determine a z-axis position of the working member relative to the working surface.

A machine tool includes a mounting table, a tool, a shade detector, and a tool controller. A workpiece is placed on the mounting table. The tool includes a tip. The shade detector is fixed on the mounting table, provides an optical path of a laser light, and detects a shade state of the laser light. The tool controller is connected to the mounting table via a supporting structure and controls an orientation and a position of the tool. A reference point associated with the tool is provided to the tool controller. The tool controller corrects a position of the tip based on a difference between a position obtained by calculation of the reference point in the case where the tip is matched with a measurement position P of a laser light and a position of the reference point when the tip portion is actually matched with a measurement position while keeping the orientation of a tool.
