A machine tool system includes a machine tool main body for machining a workpiece supported on a table by using a tool detachably attached to a spindle, and an information processing apparatus. The machine tool main body includes a rotary tool magazine in which multiple grips each capable of holding the tool to be attached to the spindle are provided along the circumferential direction, and an image pickup device that is arranged in the tool magazine and configured to take an image of multiple members in a machining area of the machine tool main body. The information processing apparatus includes a geometric feature calculating unit configured to calculate the shapes and the arrangement state of the multiple members in the machining area, based on image data of the image taken by the image pickup device.

Provided is a numerical control device capable of positioning a tool tip position in three-dimensional space with high accuracy. A numerical control device (1) includes a position compensator (5) and an error data storage (10). The error data storage (10) stores therein error data relating to angular errors (Eax, Eay, Eaz) around an X-axis, angular errors (Ebx, Eby, Ebz) around a Y-axis, and angular errors (Ecx, Ecy, Ecz) around a Z-axis in the X-, Y-, and Z-axes. The position compensator (5) calculates, based on commanded positions (Ix, Iy, Iz), the error data, and tool length data for a tool to be used, modification amounts (Mx, My, Mz) that vary in accordance with the tool length, modifies compensation amounts (Cx, Cy, Cz) for the commanded positions (Ix, Iy, Iz), and compensates for the commanded positions (Ix, Iy, Iz) with the modified compensation amounts.

An augmented reality simulation device includes: extension information display means for displaying a virtual object; relation information acquisition means for acquiring first relation information which is information that specifies relation between the virtual object and control axes of a numerical controller and second relation information which is information that specifies settings of the control axes and relation between the control axes; conversion means for converting a movement amount in a first coordinate system which is a coordinate system of the control axis to movement information in a second coordinate system which is a coordinate system for allowing the extension information display means to display the virtual object on the basis of the first relation information and the second relation information; and calculation means for calculating a display position and a display angle of the virtual object based on the movement information in the second coordinate system after the conversion.

The invention relates to a method for determining a position of a work piece and of a tool in a machine tool, in which a work piece is clamped at the machine tool, in which the tool is subsequently inserted into a rotatable spindle shaft by means of a tool holder and the spindle shaft is set into rotation, in which an electrical voltage is applied between the work piece and the tool, in which the tool and the work piece are displaced with respect to one another, and in which a variation in the applied voltage is determined in the event of a contact between the tool and the work piece, and the respective position of the work piece and/or of the tool is determined and recorded in a computing program for control/regulation of the machining of the work piece.

An adaptive workpiece support system comprising a wear plate comprising a precision datum face and a plurality of tool holes, and accessories interactive with the plurality of tool holes of the wear plate to support, locate, and hold a workpiece against the wear plate for machining the workpiece. The plurality of tool holes is laid out in a grid and extending through the precision datum face, a thickness of the wear plate, and a backside face of the wear plate. The wear plate is configured to locate a workpiece relative to three axes of a machine.

A switch housing body has a base and a sidewall having an axis and extending from the base to a rim and having a pair of axial slots. A switch cap has: a cap body having a top web; and a sidewall extending from the top web to a rim and having a pair of holes. A shaft passes through the pair of axial slots and pair of holes. A spring biases the cap axially away from the housing from a compressed condition to an extended condition. A cap electrical contact and a housing electrical contact have an electrically closed condition at the compressed condition.

The technology disclosed in the present disclosure is a method for correcting a yaw of an X-Y stage, including: moving an XY moving body in an X-axis or Y-axis direction using an actuator; measuring a yaw, which is a rotational displacement of the moved XY moving body, using a sensor; calculating, by a controller, a rotational stiffness value to be corrected, using the measured yaw data; and adding yaw correction flexures having a stiffness corresponding to the rotational stiffness value to be corrected to the X-Y stage.
