数值控制装置
摘要：
本发明涉及能够生成考虑到了移动时间，并且避免干涉的工具路径的数值控制装置。数值控制装置在决定工具从开始点到切削开始位置的移动路径中，首先，生成不与干涉物发生干涉且从开始点到切削开始位置的移动距离短的最短路径，接下来，生成一条以上的相比于该最短路径拐点数更少的代替路径。并且，分别计算最短路径的移动时间和代替路径的移动时间，将移动时间比最短路径短的代替路径决定为移动路径。
摘要（英）：

A numerical controller first creates a shortest path which does not interfere with an interfering object and shortens a movement distance from a start point to a cutting start position, and then, creates one or more alternative paths having a smaller number of break points than the shortest path when determining a movement path of a tool from the start point to the cutting start position. Then, each of a movement time along the shortest path and a movement time along the alternative path is calculated, and the alternative path having the shorter movement time than the shortest path is determined as the movement path.
