摘要： An apparatus which moves a tool back and forth in synchronism with rotation of a workpiece with respect to the workpiece to machine the workpiece into a non-circular shape. The tool is attached to a tool mount placed on a tool mount table which is connected to be moved in a direction perpendicular to the axis of a spindle by a motor. The tool is connected to be moved in a direction perpendicular to the axis of the spindle with respect to the tool mount by a high speed actuator. Profile generating movement of the tool is thus provided by a combination of movement provided by the motor and movement provided by the high speed actuator. The high speed actuator is controlled in accordance with high frequency components included in profile data while the motor is driven in accordance with low frequency components included in the profile data. As a result, the responsiveness in profile generating movement of the tool is improved, and high speed machining of a non-circular workpiece is enabled.

摘要： A method and a system for recognizing the location of a cylindrical shaft is provided for use in positioning an end effector of an industrial robot which handles said shaft. In the method and system, a multilevel gray image of the cylindrical shaft which is generated by a change coupled device (CCD) image sensor is first differentiated, and the absolute values of picture elements constituting the differentiated gray image are then binarized on the basis of a threshold value so as to extract an accentuated pattern image which is inherent to the shape of the cylindrical shaft. The accentuated pattern image thus extracted is then collated with a reference accentuated pattern image (template) so as to generate a normal curve signal which has its peak point at a position where the axis of said cylindrical shaft is located. The normal curve data is then binarized on the basis of another predetermined threshold value to generate a single strip image. The center of the single strip image is calculated to determine the location of the cylindrical shaft.

摘要： An apparatus for machining a non-circular workpiece such as a piston wherein a tool is moved back and forth against the workpiece in accordance with profile data defining a desired final shape of the workpiece while the workpiece is rotated at a predetermined speed. The tool is moved by a composite movement of a linear motor driven in accordance with low frequency command values, and a piezoelectric actuator driven in accordance with high frequency command values. A numerical controller of the apparatus calculates the low frequency command values using a first Fourier series and the high frequency command values using a second Fourier series. Coefficients of the first and second Fourier series are determined using least square method in such a way that errors contained in the low and high frequency command values becomes within a predetermined limit.

摘要： A positioning controlling device for improving the machining accuracy of a work of a non-circular shape. A control axis is driven in accordance with an input function consisting of position instruction data corresponding to a machining shape of a work, and a response function of the position of the control axis is measured actually. Then, a transfer function of the servo system is determined from Fourier transformation of the input function and Fourier transformation of the response function, and a corrected input function with which a response function of the control axis ideally corresponds to the machining shape of the work is obtained from the transfer function. Even if the control axis is driven in accordance with the corrected input function, a response function obtained does not correspond to the ideal machining shape of the work. Therefore, the calculations for obtaining an input function described above are sequentially executed until a response function obtained converges to the ideal machining shape. As a result, even if the servo system has a non-linearity, if the control axis is controlled in accordance with an input function finally obtained in this manner, then a response function then corresponds to the ideal machining shape.

摘要： An apparatus for machining a non-circular workpiece, wherein the profile data of plural sections of the workpiece stored in the profile data storage means are transformed into the frequency functions of 1 to n degree which is a function of the rotary angular velocity of the workpiece. The calculation means finds the amplitudes and the phases of each degree of the frequency function of each of plural intermediate sections by means of the interpolation according to the position between selected two sections based on the frequency functions of the selected two sections so as to obtain high frequency functions and low frequency functions which are then converted to high frequency and low frequency profile data. The machining apparatus actuates a linear motor in accordance with the high frequency profile data and actuates a PZT actuator in accordance with the low frequency profile data. The actuations of these actuators are accomplished in a synchronized relationship with the rotation of the workpiece to machine the workpiece into a non-circular shape whose sectional shape changes with respect to its axial position.

摘要： In a superabrasive grain setting method, a two-dimensionally developed coordinate preparation step is taken, wherein a non-cylindrical area of a mounting surface where a tangential line to the mounting surface in a plane including the axis of the manufacturing mold crosses with the axis of a manufacturing mold is developed into a circular-arc belt-like surface, and a plurality of mounting points are set on the circular-arc belt-like surface in a grid pattern in dependence on mounting positions for superabrasive grains. Then, a rectification step is taken, wherein the grid pattern of the mounting points is rectified in predetermined angular ranges so that the mounting points do not make consecutive point lines in the circumferential direction of the circular-arc belt-like surface. A mounting step is thereafter taken of mounting the superabrasive grains on the mounting surface of the manufacturing mold based on the grid pattern rectified at the rectification step.
