数值控制装置以及NC程序制作装置
Abstract:
一种数值控制装置以及NC程序制作装置。本发明提供一种能够对于各种材质的被加工物使工具寿命提高，并且能够进行倍率值的变更的数值控制装置。数值控制装置(10)具备：变化幅度存储部(11)，按照被加工物的材质存储进给速度或者主轴转速的倍率值的变化幅度；设定部(13b)，基于与加工中的被加工物的材质相应的倍率值变化幅度ΔRv来设定倍率值；以及控制部(13c)，基于倍率值来变更进给速度或者主轴转速。
Abstract(English):

A numerical control unit is provided that can change an override value according to various workpiece materials and can extend the tool life. A numerical control unit (10) includes a variation storage unit (11) that stores a variation in override value of a feed speed or a spindle speed for each workpiece material, an override value setting unit (13b) that sets the override value based on the variation (”Rv) in override value according to the material of a workpiece being machined; and a control unit (13c) that changes the feed speed or the spindle speed based on the override value.
