    • A numerical controller capable of reducing machining time in synchronization control machining. A workpiece already rough-machined into a shape of a gear and a tool are rotated in synchronism. Proximity limit distance Lt ensuring that the workpiece and the tool do not interfere with each other, approach amount Ap required to bring the workpiece and the tool into a positional relationship for performing normal gear machining (condition in which the workpiece engages with the tool), and phase shift amount corresponding to the depth of cut are given as commands. In parallel with approach motion, phase adjustment motion for making the workpiece face a tooth space of the tool is performed. When the approach motion progresses by the proximity limit distance Lt, if the phase adjustment is completed, the approach motion is continued without interruption. If not, the approach motion is interrupted, and resumed after the phase adjustment is completed. After the approach motion is completed, phase shift is performed to give a cut, and machining is performed. When cutting loads become a certain value or smaller, it is determined that the machining is completed. Since the approach motion and the phase adjustment are performed concurrently and completion of machining is automatically determined, the machining time can be reduced.
    • 一种能够减少同步控制加工中的加工时间的数值控制器。 已经粗加工成齿轮和工具的工件的工件同步旋转。 接近极限距离Lt确保工件和工具彼此不干涉,使工件和工具进入正常齿轮加工(工件与工具接合的状态)所需的位置关系所需的接近量Ap, 并且相应于切割深度的相移量作为命令给出。 与进场运动并行,执行用于使工件面对工具的牙齿空间的相位调整运动。 当接近运动进行接近极限距离Lt时,如果相位调整完成​​,则连续运动不间断地继续。 如果没有,则进场运动中断,并在相位调整完成​​后恢复运行。 进场动作结束后,进行相移切断,进行加工。 当切削负载变为一定值或更小时,确定加工完成。 由于进行运动和相位调整同时进行,并且自动确定加工完成,因此可以减少加工时间。
