Description

공작기계의 공구이상 검출장치{Apparatus for detecting malfunction of tool for machine tool}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

본 발명은 공작기계의 공구이상 검출장치에 관한 것이다. 보다 상세하게 설명하면, 수치제어기능(Numeric Control)을 가지는 공작기계의 운전시에 발생할 수 있는 공구의 마모상태, 공구와 소재 간의 이상상태 또는 프로그램에 의해 동작되는 공작기계의 이상상태 등을 효과적으로 검출하기 위해 전류감지센서, 전압감지센서 이외에 유량센서 및 온도센서 등을 이용하는 공작기계의 공구이상 검출장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] More specifically, the present invention can effectively detect a wear state of a tool that may occur during operation of a machine tool having a numerical control function (Numeric Control), an abnormal state between a tool and a workpiece, or an abnormal state of a machine tool operated by a program And more particularly, to a tool abnormality detecting device for a machine tool using a flow sensor and a temperature sensor in addition to a current sensor and a voltage sensor.

최근 전자기술의 발달과 더불어 더욱 정밀하면서도 수치제어 기능을 가지는 공작기계가 다양하게 개발되어 사용되고 있다.With the recent development of electronic technology, machine tools having more precise numerical control functions have been developed and used.

특히 이러한 공작기계를 사용하여 소재를 가공하는 경우 통상 공구의 마모 정도, 또는 공구와 소재 간의 접촉상태나 공작기계에의 공구의 설치상태 등에 따라 가공 정밀도 등이 달라진다. Particularly, when machining a material using such a machine tool, the machining accuracy depends on the degree of abrasion of the tool, the contact state between the tool and the material, and the installation state of the tool on the machine tool.

따라서 이러한 공구 마모의 정도, 공구와 소재 간의 접촉상태 등을 확인하기 위해서는 작업자가 가공 후의 공작물의 가공상태 또는 공구의 마모 정도를 수시로 육안으로 확인하여야 하며, 또한 육안으로 공구의 마모상태와 공작물의 가공상태를 확인하는 경우에도 작업자의 숙련도에 따라 그 판단 결과가 다르고, 또한 공구를 공구대에 장착하는 상태도 작업자의 숙련도에 따라 다르며, 따라서 작업자에 따라 공작물의 가공 품질과 공구의 수명 등에 있어서 차이가 있다.Therefore, in order to check the degree of such tool wear and the contact state between the tool and the workpiece, the operator must visually check the machining state of the workpiece after machining or the degree of wear of the tool from time to time. Even if the state is checked, the judgment result is different according to the skill level of the worker, and the state in which the tool is mounted on the tool stand is also different according to the skill level of the worker. Therefore, depending on the worker, there is a difference in the working quality of the workpiece and the tool life have.

결국 공작기계의 공구를 이용해 소재를 가공할 때 사람의 육안이 아닌 객관적이고 정확한 방법으로 공작기계의 이상여부 등을 검출할 수 있는 시스템이 필요한 상황이다. As a result, when machining a material using a tool of a machine tool, it is necessary to have a system that can detect the abnormality of the machine tool in an objective and accurate manner, not a human eye.
