    • PROBLEM TO BE SOLVED: To shorten a working time in a working by synchronous control. SOLUTION: A workpiece 1 roughly worked to be in a gear shape is synchronously controlled by a tool 2, so as to be rotated at the same speed. An approach limit distance Lt for preventing an interference between the workpiece 1 and the tool 2, an approach amount Ap for obtaining a normal gear working state (the engagement of the workpiece with the tool), and a phase shift amount corresponding to an amount of cutting in are commanded. A phase matching operation where the teeth of the workpiece face the gear grooves of the tool is performed in parallel with an approach operation. When a distance becomes the approach limit distance Lt, the approach operation is performed as it is when the phase matching operation is completed. The approach operation is stopped when the operation is not completed, and restarted after the completion of the phase matching operation. After the approach operation is completed, phase shift is performed, so as to give a cut-in for working. The completion of the working is determined when a cutting load becomes not more than a fixed amount. The approach operation is performed in parallel with the phase matching operation. Since the completion of the working is automatically determined, the working time is shortened. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:通过同步控制缩短工作时间。 解决方案:粗加工成齿轮形状的工件1由工具2同步控制,以便以相同的速度旋转。 用于防止工件1和工具2之间的干涉的接近极限距离Lt,用于获得正常齿轮工作状态(工件与工具的接合)的接近量Ap和与 砍伐被命令。 执行工件的齿与工具的齿轮槽的相位匹配操作,与进近操作并行执行。 当距离成为接近极限距离Lt时,在相位匹配操作完成时进行接近操作。 当操作未完成时,接近操作停止,并且在完成相位匹配操作之后重新启动。 在接近操作完成之后,进行相移,以便进行切入。 当切割负载变得不大于固定量时,确定加工完成。 进行操作与相位匹配操作并行执行。 由于工作完成自动确定,工作时间缩短。 版权所有(C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To adjust operation of a gear grinding machine so as to positively correcting a tooth profile error or a total alignment error on a ground gear if any.
      SOLUTION: To correct the tooth profile error on the ground gear, a grinding tool angle of a screw-shaped grinding tool 3 is corrected by dressing with a dressing apparatus 10. To correct the total alignment error on the ground gear, that is, to correct a helix angle of the gear, synchronizing operation of Z-direction movement of the screw-shaped grinding tool 3 with rotational movement of a table 4 for mounting the gear is adjusted. The correction of the total alignment error by the synchronizing operation inevitably generates tooth profile deformation, therefore the tooth profile error is corrected by dressing in consideration of the tooth profile deformation.

    • 要解决的问题:调整齿轮磨床的操作,以便积极地校正齿轮齿轮的齿廓误差或总的对准误差(如果有的话)。

      解决方案:为了校正齿轮的齿廓误差,用修整装置10修整螺丝状研磨工具3的研磨工具角度。为了校正地面齿轮上的总对准误差, 为了校正齿轮的螺旋角度,调整螺旋形磨削工具3的Z方向运动与用于安装齿轮的工作台4的旋转运动的同步操作。 通过同步操作校正总对准误差不可避免地产生齿廓变形,因此考虑到齿廓变形来修整齿廓误差。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To synchronize two shafts with each other even when abnormality occurs in communication lines between a control device and motors.SOLUTION: In a first synchronization system of a synchronization control device (1), movement instructions synchronized with each other for a first motor (23) and a second motor (13), which are generated by a movement instruction generation part (9) are supplied to a first amplifier (22) and a second amplifier (12) via a first communication line (11) and a second communication line (21) respectively. In a second synchronization system switched from the first synchronization control system, the first motor (23) is decelerated by a deceleration instruction generated by a deceleration instruction generation part (29), and the second motor (13) is decelerated synchronously with the first motor by a movement instruction generated on the basis of a position feedback value which is supplied to the second amplifier (12) via a third communication line (31) and is controlled by the first motor (23).
