Abstract
In a numerical control device for machine tools, a tool path is determined for a workpiece according to the machining data, and is divided into machining units, and the amount of machining for each machining unit is calculated to set a tool feeding speed data thereby to control the tool feeding speed of the machine tool.
Claims8
A numerical control device for controlling numerical control machine tools adapted to perform three-dimensional machining operations, which comprises:
- machining-locus calculating means for determining a tool path according to machining data such as machining dimensions;
- machining-unit forming means for dividing said tool path thus determined into machining units;
- machining-amount calculating means for calculating the amount of machining of a workpiece for each of said machining units of said tool path;
- speed parameter setting means for setting a tool feeding speed parameter according to said amount of machining thus calculated or the like;
- and
- tool feeding speed calculating means for controlling a tool feeding speed according to said tool feeding speed parameter thus set.
