Abstract
A control device, which controls a machine tool capable of alarm stop based on abnormality in machining load, includes: a photographing unit which photographs chips produced as a result of machining of a workpiece; a reference model determination unit which determines in advance a reference model of chips for determining as abnormality in machining, based on images of chips photographed within a predetermined period before alarm stop, in response to an occurrence of alarm stop; and a judgment unit which judges as abnormality occurrence in machining, in a case of a degree of similarity in chips photographed at a predetermined timing in machining later, relative to a reference model of chips that was determined.
Claims6
A control device which controls a machine tool capable of alarm stop based on abnormality in machining load, the control device comprising:
- a camera which photographs chips produced as a result of machining of a workpiece;
- and
- a processor, the processor being configured to:
- determine in advance a reference model of chips for determining as abnormality in machining, based on images of chips photographed within a predetermined period before alarm stop;
- and
- judge as abnormality occurrence in machining, in a case of a degree of similarity in chips photographed at a predetermined timing in machining later, relative to the reference model of chips that was determined, wherein
- the processor initiates compensating the reference model being determined, based on images of chips photographed within a predetermined period before a new alarm stop, in response to an occurrence of the new alarm stop.
A non-transitory computer readable medium storing a program for causing a computer to operate as a control device which controls a machine tool capable of alarm stop based on abnormality in machining load, the program causing the computer to function as:
- a photographing unit which photographs chips produced as a result of machining of a workpiece;
- a reference model determination unit which determines in advance a reference model of chips for determining as abnormality in machining, based on images of chips photographed within a predetermined period before alarm stop, in response to an occurrence of alarm stop;
- and
- a judgment unit which judges as abnormality occurrence in machining, in a case of a degree of similarity in chips photographed at a predetermined timing in machining later, relative to the reference model of chips that was determined, wherein
- the reference model determination unit initiates compensating the reference model being determined, based on images of chips photographed within a predetermined period before a new alarm stop, in response to an occurrence of the new alarm stop.
