    • PROBLEM TO BE SOLVED: To provide a numerical control device which does not generate pile of deceleration when turning back at a boundary point, can realize accuracy improvement of the boundary point, can change speed at any interval which matches fluctuation control, and has a fluctuation operation function which can change speed at any interval in which a processing cycle time can be shortened while maintaining accuracy.SOLUTION: A fluctuation operation command code is analyzed, a top dead point location is set as Z, a bottom dead point location is set as Z, reference speed of fluctuation operation is set as F, a current location is acquired, and z is substituted by Z(SA100 to SA102). A current phase is calculated, current speed is calculated, and the location is updated (SA103 to SA105). It is determined whether termination is instructed, and the process is terminated if the termination is instructed. In addition, it is determined whether data change is instructed if the termination is not instructed. The process proceeds to a step SA101 when changing data. In addition, the process proceeds to a step SA102 when not changing data.
    • 要解决的问题:提供一种在边界点回转时不产生减速的数值控制装置,可以实现边界点的精度提高,可以随波动控制匹配的任何间隔改变速度,以及 具有可以在保持精度的同时缩短处理周期时间的任何间隔来改变速度的波动运算功能。 解决方案:分析波动运算命令代码,将上死点位置设定为Z U ,下死点位置设为Z L ,起动运转的参考速度设定为F B ,获取当前位置,z代入Z (SA100到SA102)。 计算当前相位,计算当前速度,并更新位置(SA103至SA105)。 确定是否指示终止,如果指示终止,则该过程终止。 此外,如果没有指示终止,则确定是否指示数据改变。 当改变数据时,处理进行到步骤SA101。 此外,当不改变数据时,处理进行到步骤SA102。 版权所有(C)2012,JPO&INPIT
