    • The diameter, the orientation flat width/notch depth and the length of the block 10p are measured by the measuring devices 71a, 71b and 71c respectively and then the machining errors .DELTA.Dp, .DELTA.Wp and .DELTA.Lp in the measured values against the set values are calculated at the error calculation unit 833. Then .DELTA.Dp, .DELTA.Wp and .DELTA.Lp are stored in memory at the memory unit 834 in correspondence with the identification codes IDi and IDj of the grinding device 5i (i=1-N) and the cutting device 6j (j=1-M) that performed the machining. Then at the average value calculation unit 835, the average values of .DELTA.Dp and .DELTA.Wp for each of the grinding devices 51-5N and the average value of the .DELTA.Lp for each of the cutting devices 61-6M are calculated. The average values of .DELTA.Dp and .DELTA.Wp are supplied to the corresponding grinding device 5i as the diameter correction value and the width/depth correction value respectively and the average value of .DELTA.Lp is sent to the corresponding cutting device 6j as the length correction value from the transmission unit 836.

    • In a numerical control grinding machine using a grinding wheel made of cubic boron nitride, a computerized numerical controller controls the infeed movement of a wheel head to effect a rough grinding, a drifty grinding and a fine grinding on a rotating cylindrical workpiece. The drifty grinding due to a spring-back motion which is caused by a flexed workpiece is initiated in response to a sizing signal from a sizing device which measures the workpiece diameter varying momentarily during the grinding operation and is terminated upon the expiration of a predetermined time which is sufficient to vanish the variation of the workpiece diameter. A sizing device measures the actual diameter thereafter, and the sizing signal is compensated in order to approximate the actual diameter to a desired set size which is the sum of a finish diameter and a predetermined allowance for the subsequent fine grinding operation, as the number of the workpieces increases. That is, the numerical controller diminishes a set size which determines the time point to issue the sizing signal from the sizing device, toward the desired set size on a step-by-step basis with the increase in number of the workpieces ground.
    • 在使用由立方氮化硼制成的砂轮的数控磨床中,计算机化数值控制器控制轮头的进料运动,以便在旋转的圆柱形工件上进行粗磨,精磨和细磨。 由弯曲工件引起的由回弹运动引起的驱动磨削响应于来自尺寸测量装置的施胶信号而启动,该尺寸测量装置测量在研磨操作期间瞬间变化的工件直径,并且在预定时间期满时终止 这足以消除工件直径的变化。 尺寸测量装置此后测量其实际直径,并且对尺寸信号进行补偿,以将实际直径近似为期望的设定尺寸,即作为后续精磨操作的精加工直径和预定余量之和的所需设定尺寸为 工件增加。 也就是说,随着工件数量的增加,数字控制器减小了设定尺寸,该尺寸确定了从尺寸调节装置发出尺寸信号的时间点,逐步地朝着期望的设定尺寸。

    • An automatic control for a grinding system is disclosed for controlling the advancement of a grinding wheel into a workpiece to provide a substantially constant time span between the termination of the operation of the feed means which advances the grinding wheel and the attainment of the final size of the workpiece for each workpiece machined. The control generates a reference time span and if the actual time span deviates by more than a preselected time period from the reference time span, the control develops a control signal adjusting the advancement of the grinding wheel during the grinding of the following workpiece.

    • An apparatus for evaluating the shape of a three-dimensional object by comparing direct measurements of the surface of an actual worked version of the object with its ideal shape. A representation of an ideal surface of the object based upon reference data is set within a given space. A worked surface of the object is also set within the given space, based upon measurements of the worked surface at several measurement points. A processor calculates the intersection point on the ideal surface of the line extending from each of the measurement points that perpendicularly intersects the ideal surface. The distance between each intersection point and its corresponding measurement point is calculated to evaluate the precision of the worked surface.
