Abstract
The purpose is to provide a numerical control device that can easily suppress the occurrence of burrs. The numerical control device comprises: an analysis unit that analyses a processing program for processing a workpiece in a machine tool; and a corner specifying unit that specifies the corner that causes burrs on the workpiece based on the analyzed processing program.
Claims6
A numerical control apparatus for controlling a machine tool that machines a workpiece, comprising:
- a processor,
- wherein the processor is configured to:
- analyze a machining program for machining the workpiece in the machine tool;
- identify a protruding corner part that causes burrs to occur on the workpiece, based on the analyzed machining program;
- analyze a positional relationship of the workpiece in the machining program based on a direction of a release operation of releasing a tool of the machine tool from a cutting end position, in the machining program;
- identify the protruding corner part based on the positional relationship of the workpiece in the machining program and a change in a movement direction of a program command path of the machining program;
- modify the machining program to machine the protruding corner part in a curved shape;
- and
- control the machine tool to machine the workpiece based on the modified machining program.
