摘要： There are provided a concentric machining device and method. The concentric machining device is used to machine the outer curcumferential surface of a cylindrical body having an inner diameter and an outer diameter with respect to the center of the inner diameter so that the center of the outer diameter is identical with the center of the inner diameter. In the concentric machining device, the cylindrical body is mounted in a mounting means installed in a rotating means. The rotating means rotates the mounting means and the cylindrical body according to a rotation control signal. A photographing means photographs the cross-section of the cylindrical body. A controlling means generates the rotation control signal to rotate the rotating means at a predetermined angle when the cylindrical body is mounted, calculates an eccentricity being the difference between the inner diameter center of the cylindrical body and a rotation center of the rotating means from information about the photographed cross-section received from the photographing means, and generates a machining control signal corresponding to the eccentricity. A transferring means transfers the machining control signal, and an adjusting means adjusts the position of the cylindrical body according to the machining control signal received from the transferring means so that the inner diameter center of the cylindrical body is identical with the rotation center of the rotating means.

摘要： A device is provided for measuring roundness of a mechanical object even if the mechanical object performs an orbit movement. The orbital movement and the surface roundness are separated. It is even possible to divide the orbital movement into an x component and a y component. The measurement is accomplished in a single measurement. After measuring it is possible to decide what to indicate: the orbit of the mechanical object, the deviation from a nominally round surface, or the combination of both. This is possible since once the data has been obtained it is then possible to use the data once or a number of times to indicate the orbit of the mechanical object, the deviation from a nominally round surface, or the combination of both.

摘要： An apparatus for detecting machining conditions in a machine tool has a magnetic bearing for magnetically supporting a work spindle or a tool spindle. An exciting current detector is provided for detecting an exciting current of an electromagnet of the magnetic bearing. The exciting current corresponds to various machining conditions including the conditions when the machine tool starts operating, the tool contacts the workpiece to follow various unfinished faces, and a machining face condition of the workpiece during machining. The detection signals from the exciting current detector are inputted to a plurality of frequency band pass filters to discriminate the machining conditions. Comparators are provided to compare the output signals from the frequency band pass filters with a predetermined set of reference values, and comparative judgment signals are inputted to a control unit, thereby controlling the machine tool to automatically perform appropriate machining operations.

摘要： A method is described for grinding a composite workpiece to form a component having concentric and eccentric cylindrical regions. The method comprises mounting the workpiece in a computer controlled grinding machine having a grinding wheel the advance and withdrawal of which is controllable by a program entered into the controlling computer, loading a wheelfeed controlling program into the computer, relatively positioning the grinding wheel and the workpiece to align the wheel with a first selected region of the workpiece, advancing the grinding wheel towards the selected region so as to grind the surface thereof, controlling the wheelfeed so as to maintain grinding contact between the grinding wheel and the workpiece so as either to grind a concentric cylindrical region thereon or an offset cylindrical region thereon as required, information about each selected region of the workpiece being stored in the computer and addressed as appropriate so that the wheelfeed can be controlled appropriately depending on whether a selected workpiece region is to be ground as a concentric or an offset cylindrical region. The method allows a workpiece having both concentric and offset cylindrical regions thereon to be ground using a single grinding machine under computer control without demounting the workpiece from the machine. A computer controlled grinding machine is described as are programs for controlling the machine.

摘要： A method and apparatus for treating a circumferential edge of a part are described. The method includes the steps of (1) mapping the circumferential edge of the part with a measuring device, either directly or differentially from a known shape profile; and (2) using the measured data to more accurately follow the circumferential edge of the part during subsequent treatment processing steps, thereby improving the accuracy of the treatment process and compared with a non-mapped treatment process.

摘要： An object is mounted and rotated on a rotary table. An encoder outputs a rotary angle signal corresponding to the rotary angle of the rotary table. A detection head outputs a displacement detection signal while tracing the surface of the object. The detection head moves within a plane including the axis of rotation, so as to oppose the outer or inner surface of the object. When the detection head is opposed to the inner surface of the object, the positive and negative signs of the displacement detection signal is reversed, while at the same time a 180.degree. angle is added to the rotary angle signal. By utilizing the reversed displacement detection signal and the corrected angle correction signal, the obtained result can be displayed through a displaying processing common to the processing for the outer surface.

摘要： The invention is a method for positioning a conveying mechanism having a holding portion for semiconductor wafers. Respective provisional position coordinates of an orienting teaching standard position and a container teaching standard positions are inputted into a controlling unit in advance. A wafer to be conveyed precisely positioned with respect to and held by the holding portion is conveyed and placed on the rotating orienting device according a control based on the provisional coordinates of the orienting teaching standard position. A posture detector then detects the eccentric volume and eccentric direction of the wafer. Appropriate position coordinates are made by amending the provisional coordinates. Then, a wafer to be conveyed precisely positioned with respect to the container teaching standard position is conveyed and placed on the rotating orienting device according a control based on the provisional coordinates of the orienting teaching standard position. A posture detector then detects the eccentric volume and eccentric direction of the wafer. Appropriate position coordinates are made by amending the provisional coordinates.

摘要： It is assumed that an element to be detected 2a in a position sensor is mounted on a rotary shaft with the center O′ of the element to be detected eccentric from a center of rotation O by a distance d. When the rotary shaft is rotated at a fixed speed, the positions at angles 0° and 180° are accurately detected by a sensor 2b, while the positions at angles 90° and 270°, the sensor detects the positions P1′ and P3′, instead of P1 and P3 which are originally to be detected, resulting in undulation of detected positions as shown in FIG. 3(b). The peak value of the unduration and an angle of rotation at which the peak value is found are determined. An amount of eccentricity d is found from the peak value, a detection error with respect to the command position (angle) is found from the amount of eccentricity d and the angle at which the peak value is found, and correction the by detection error is made with respect to the command position, providing a corrected command position to a motor.
