    • Disclosed is a numerical controller capable of foreseeing the occurrence of interference during operation of a machine and securely preventing the interference. An advanced position calculating section determines advanced time for the next interference check, based on an end time point of an interference check by an interference checking device and the sum of a time required for the interference check, a time required for communication, a time required for decelerating and stopping a movable part, and a predetermined float. Further, an advanced position of the movable part at the advanced time is calculated based on pre-read program data and is outputted to the interference checking device. The interference checking device performs the interference check at the advanced position. If it detects interference, the interference checking device delivers an axis stop signal to a motion command output section, thereby stopping a motion command and decelerating and stopping the movable part. Since interference check timing is settled in accordance with the time required for the interference check, the occurrence of interference can be securely prevented without delay or advance.
    • 公开了一种数字控制器,其能够预见机器操作期间的干扰发生,并可靠地防止干扰。 高级位置计算部分基于干扰检查装置的干扰检查的结束时间点和干扰检查所需的时间之和,通信所需的时间,所需的时间,确定下次干扰检查的高级时间 用于减速和停止可移动部件和预定浮子。 此外,基于预先读取的程序数据计算可动部件在高级时间的高位置,并将其输出到干扰检查装置。 干扰检查装置在高级位置进行干扰检查。 如果检测到干扰,则干扰检查装置向运动指令输出部输出轴停止信号,从而停止运动指令,减速停止可动部。 由于根据干扰检查所需的时间来确定干扰检查定时,所以可以在不延迟或提前的情况下可靠地防止发生干扰。
