摘要： In a method and apparatus for grinding a workpiece, a rotating workpiece and a rotating grinding wheel are relatively moved toward and away from each other, and at least first and second grinding steps are performed at high and low infeed rates, respectively. Further, back-off grinding is performed between the first and second grinding steps. A target workpiece diameter to be obtained at the end of the back-off grinding is first provided. During the rough grinding, prediction is repeatedly performed to obtain a workpiece diameter which would be obtained at the end of the back-off grinding if the back-off grinding were started instantaneously. The workpiece diameter is predicted taking account of a delay in the movement of the grinding wheel. The back-off grinding is started when it is judged that the predicted workpiece diameter becomes equal to the target workpiece diameter.

摘要： An apparatus for detecting a residual grinding amount includes first and second feelers adapted to contact the peripheral surface of a workpiece such that they move, in accordance with a variation in the diameter of the workpiece, in opposite directions each perpendicular to the direction of deflection of the workpiece, and a first displacement detector for detecting relative displacement between the first and second feelers. The apparatus also includes a third feeler adapted to contact the peripheral surface of the workpiece such that it moves, in accordance with the variation in the diameter of the workpiece as well as a variation in the deflection of the workpiece, in the direction of deflection of the workpiece, and a second displacement detector for detecting displacement of the third feeler. The residual grinding amount is calculated based on the displacements detected by the first and second displacement detectors.

摘要： A numerically controlled machine tool for machining a non-circular workpiece according to profile data. The numerical controller of the machine tool memorizes the ideal profile data calculated from the ideal final shape of the workpiece, and the execution profile data calculated from the ideal profile data and compensated for position error due to the follow delay of the machine tool. The machine tool is controlled according to the execution profile data during grinding the workpiece with cut-in feed and spark-out grinding. The numerical controller has the capability of measuring position change of the main spindle and the tool slide during spark-out grinding. Then, the numerical controller ascertains whether or not the follow delays of the main spindle and the tool slide are within a prescribed tolerance depending on the measured position change and the ideal profile data.

摘要： A numerical controlled grinding machine for grinding a workpiece, in which a thermal displacement taking place between a wheel head and the workpiece, is detected with the workpiece not being subjected to the bending due to a grinding resistance. The thermal displacement is calculated from the difference between the present position of the wheel head detected by a position detector and the theoretical position thereof converted from the diameter of the workpiece measured by an in-process measuring device. The position data for the wheel head stored in a numerical controller is compensated for the calculated thermal displacement for use in the subsequent control of feed movement between the workpiece and the wheel head.
