A tool cutting edge measuring device that is mounted on a horizontal lathe and multitasking machine includes contact type sensors and an arm. The sensors are configured to measure cutting edge positions of tools in a machining chamber and the arm is movable between an advance position and a retracted position. The arm advances into the machining chamber at the advance position and retracts from the machining chamber at the retracted position. The arm has distal ends provided with two branching units branched into the X-axis direction and the Z-axis direction at the advance position and the sensors are mounted to the respective branching units.

An apparatus capable of accurately determining a robot coordinate system of a robot configured to be moved along an axis. The apparatus of setting the robot coordinate system of the robot configured to be moved along a first axis includes a coordinate system acquisition section configured to determine, from positions of two robot coordinate systems preset along the first axis, a position of another robot coordinate system to be set between the positions of the two robot coordinate systems by calculation. Further, a method of setting a robot coordinate system of a robot configured to be moved along a first axis includes determining, from positions of two robot coordinate systems preset along the first axis, a position of another robot coordinate system to be set between the positions of the two robot coordinate systems by calculation.

A machine tool includes a main spindle movably supported in an axial direction, and two gang tool posts disposed opposed to each other with an axis of the main spindle located therebetween. Each of the two gang tool posts is supported movably in X and Y directions that are perpendicular to the axial direction of the main spindle. Each of the two gang tool posts is provided with tools arranged parallel to each other in the Y direction. One of the two gang tool posts is movably disposed in a Z direction that is a same direction as the axial direction of the main spindle. Any one of the two gang tool posts is integrally provided with a turning tool base that turnably supports tools about a Y-axis along the Y direction.

The present disclosure provides a numerical control machine and a cutting method. The numerical control machine includes a workpiece seat for fixing a workpiece, a cutting tool, a non-contact measurement component for measuring a contour of a surface to be machined of the workpiece, a power component and a control component. The workpiece seat is rotatable relative to the cutting tool or the non-contact measurement component under driving of the power component, and/or the cutting tool is rotatable relative to the workpiece seat under the driving of the power component. Both the cutting tool and the non-contact measurement component are mounted on the numerical control machine, and distances from the workpiece seat to both is adjustable. The control component is electrically connected with the non-contact measurement component and the power component.

A tool alignment device for mounting on a tool having a stop, especially on a drilling and/or countersinking tool having a single-piece tool shaft and a stop, for alignment of a drill hole and/or countersink to be introduced or for alignment of a finishing step in relation to a normal to the surface of a workpiece, comprising a main part and a through hole. Upon mechanical contact between the tool alignment device and the surface of the workpiece, a signaling device is actuated and emits alignment signal(s) during alignment in an alignment direction, and the stop of the tool can be accommodated in the main part, which comprises a guide device which establishes a connection between a stop sleeve of the stop and the tool alignment device such that the stop can be aligned in the alignment direction. Also, a drilling, milling and/or countersinking tool having a stop.
