Abstract
A tool damage detection device includes: a data acquisition unit that acquires load data indicating a load of a spindle and rotational speed data indicating a rotational speed of the spindle in a cutting feed section; an extraction unit that extracts, from the load data, evaluation data to be used for evaluation of occurrence of damage to a tool based on the rotational speed data; a detection unit that detects occurrence of damage to the tool using the evaluation data; and an output unit that outputs data indicating occurrence of damage to the tool when the detection unit detects the damage to the tool.
Claims9
A tool damage detection device, comprising:
- a data acquisition unit that acquires load data indicating a load of a spindle and rotational speed data indicating a rotational speed of the spindle in a cutting feed section;
- an extraction unit that extracts, from the load data, evaluation data to be used for evaluation of occurrence of damage to a tool based on the rotational speed data;
- a detection unit that detects the occurrence of damage to the tool using the evaluation data;
- an output unit that outputs data indicating the occurrence of damage to the tool when the detection unit detects the damage to the tool;
- and
- a control unit that issues an alarm indicating the occurrence of damage to the tool when the detection unit detects the damage to the tool, and stops an operation of the tool when the alarm is issued.
A computer-readable non-transitory storage medium storing an instruction that causes a computer to:
- acquire load data indicating a load of a spindle and rotational speed data indicating a rotational speed of the spindle in a cutting feed section;
- extract, from the load data, evaluation data to be used for evaluation of occurrence of damage to a tool based on the rotational speed data;
- detect the occurrence of damage to the tool using the evaluation data;
- output data indicating the occurrence of damage to the tool when the damage to the tool is detected;
- issue an alarm indicating the occurrence of damage to the tool when the damage to the tool is detected;
- and
- stop an operation of the tool when the alarm is issued.
