摘要： In a grinding machine, a retraction grinding is performed after a first advance grinding. Within a rotational range for a cylindrical workpiece to rotate from a present rotational phase to a target rotational phase in the retraction grinding, target grinding resistances in respective rotational phases are generated based on residual grinding amounts in the respective rotational phases of the cylindrical workpiece. Then, the retraction grinding is performed and controlled to make a grinding resistance detected by a force sensor agree with the target grinding resistances in respective rotational phases.

摘要： A control unit that relatively moves a headstock and tailstock and a tool to thereby machine a peripheral surface of a workpiece in a radial direction executes control such that a relative feed speed of the tool in the radial direction in a transitional state where an amount of warpage of the workpiece in the radial direction at a machining position increases is faster than a relative feed speed of the tool in the radial direction in a steady state where an amount of warpage of the workpiece in the radial direction at the machining position is constant. By so doing, it is possible to reduce a machining time at the time of the start of machining.

摘要： A circular or non-circular workpiece is ground in a plurality of grinding steps, including a final finish grinding step. A grinding wheel is caused to effect profile generation movement in synchronism with rotation of the workpiece and in accordance with profile data derived from the target shape of the workpiece. In each grinding step, the grinding wheel is advanced in such a manner that the grinding wheel causes cut-in movement within a predetermined cut-in angle defined on the workpiece. After completion of the final finish grinding step, the grinding wheel is retracted over a predetermined back-off angle defined on the workpiece. The retraction is effected in accordance with composite data obtained through combining the profile data and back-off data. The back-off angle is greater than the cut-in angle employed during the final finish grinding step.
摘要翻译：在多个研磨步骤中研磨圆形或非圆形工件，包括最后精加工步骤。导致砂轮与工件的旋转同步并且根据从工件的目标形状导出的轮廓数据来实现轮廓产生运动。在每个研磨步骤中，砂轮以这样的方式前进，使得砂轮在限定在工件上的预定切入角度内引起切入运动。在完成最终精磨步骤之后，将砂轮缩回到在工件上限定的预定的后退角度上。根据通过组合简档数据和退避数据获得的复合数据实现缩回。后退角度大于在最终精磨步骤期间使用的切入角度。

摘要： In a swivel device, a swivel head provided with a plurality of tool spindles thereon is mounted on a support base to be turnable about a swivel shaft being upright on the support base. An annular space portion is formed between the support base and the swivel head in coaxial relation with the swivel shaft. The tool spindles each mounting a grinding wheel are arranged on the swivel head to extends in a horizontal plane which crosses the annular space portion at about a mid position in the vertical direction of the annular space portion. A direct drive motor is built in the annular space portion so that a driving center of the direct drive motor is at almost the same height as the horizontal plane including the axes of the grinding wheels. Thus, the swivel device can lower the positions of the rotational axes of the grinding wheels and is rigid against inclination caused by grinding resistance acting on the grinding wheels.

摘要： In a truing method and apparatus, an analyzing method is employed to calculate a truing shape from which a grinding surface having been trued with a grinding wheel being rotated at a low rotational speed during a truing operation is deformed to a desired shape due to centrifugal expansion depending on a rotational speed difference when the grinding wheel is rotated at a high rotational speed during a grinding operation. Then, with the grinding wheel being rotated at the low rotational speed, the grinding surface is trued with a truing roll to the calculated truing shape. As a result, the grinding surface of the grinding wheel being rotated at the low rotational speed is trued with the truing roll taking into consideration the centrifugal expansion of the grinding surface which takes place when the grinding wheel is rotatated at the high rotational speed during the grinding operation subsequent to the truing operation.
