일반적으로 NC(Numerical Control)공작기계는 수치와 부합으로 구성된 수치정보로 기계의 운전을 자동제어하는 공작기계를 말하며 복잡한 2차원 혹은 3차원의 형상을 가공하는데 용이하게 높은 정밀도로 단시간에 가공할 수 있도록 하는 것이다. 이러한 NC공작기계가 보급됨에 따라 복잡한 형상을 한 기계부품의 가공을 쉽게 실시할 수 있게 되어있다.In general, NC (Numerical Control) machine tool refers to a machine tool that automatically controls the operation of the machine with numerical information configured in accordance with the numerical value, and can be processed in a short time with high precision to easily process complex two-dimensional or three-dimensional shapes. To ensure that With the spread of these NC machine tools, machine parts with complex shapes can be easily processed.

본 발명은 상기 NC공작기계에 관련된 발명으로서 기계가공품을 3차원검사장치(CMM ; 3 Coordinate Measuring Machine)로 검사할 때 적용되는 것이다.The present invention is an invention related to the NC machine tool is to be applied when inspecting a machined product by a three-dimensional inspection machine (CMM; 3 Coordinate Measuring Machine).

이제까지 3차원적 측정은 정반위에서 직각자, 하이트게이지 또는 하이트 마이크로미터 등의 기준도구, 전기마이크로미터 또는 지렛대식 다이얼 테스트인디케이터 등의 측정도구, V블록, 스탠드, 및 각종 치공구를 이용하여 측정해 왔다.So far, three-dimensional measurements have been made with reference tools such as square, height gauge or height micrometers, measuring tools such as electric micrometers or lever dial test indicators, V-blocks, stands, and various tools on the face. .

이에 대해 3차원검사장치는 테이블 위에 측정물을 두고 기준으로 하는 면을 프로브의 측정자로 접촉하여 그 위치를 결정하고 측정물이 필요로 하는 곳을 프로브로서 순차적으로 더듬으로써 그 면에서 형체의 위치, 자세, 거리 등을 컴퓨터에 의해 구하고 그것들의 결과를 타이프라이터나 플로터 등으로 출력하게 되어있다.On the other hand, the 3D inspection apparatus places the workpiece on the table and contacts the reference surface with the probe's measurer to determine its position, and then stirs the spot where the workpiece is needed as a probe to position the shape, Postures, distances, etc. are obtained from a computer and the results are output to a typewriter or plotter.

한편 기계가공품을 상기 3차원검사장치로 검사시 제로포인트(Zero-Point)를 설정하고 검사에 들어가게 되는 바, 종래에는 도 3에 도시한 바와 같은 형상의 툴링볼(10 ; Tooling Ball)을 이용하여 이를 수행하였다.Meanwhile, when the machined product is inspected by the 3D inspection apparatus, a zero point is set and the inspection is performed. Conventionally, a tooling ball 10 having a shape as shown in FIG. 3 is used. This was done.

상기한 종래의 툴링볼(10)은 도 4에 도시한 바와 같이 검사홀(31)에 삽입하여 사용하게 되는 바, 검사홀(31)이 관통되지 않은 것이라면 도면에 화살표로 도시한 바와 같이 상기 검사홀(31) 내부의 공기압으로 인하여 툴링볼(10)이 밀려 나오는 상황이 발생된다. 이는 미세한 양의 움직임이지만 검사 데이터에 영향을 주게 되어 정확한 측정이 곤란하다는 문제점이 있다.The conventional tooling ball 10 is inserted into the inspection hole 31 to be used as shown in FIG. 4, and if the inspection hole 31 is not penetrated, the inspection as shown by the arrow in the drawing A situation in which the tooling ball 10 is pushed out due to the air pressure inside the hole 31 occurs. This is a minute amount of movement but affects the inspection data, which makes it difficult to accurately measure.

따라서 본 발명은 상기한 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 툴링볼을 검사홀에 삽입시 공기압으로 인하여 툴링볼이 밀려 나와 검사의 오차를 초래하는 것을 방지하기 위한 에어홀이 구비된 툴링볼을 제공하는 데 있다.Therefore, the present invention has been made in view of the above problems, an object of the present invention is provided with an air hole for preventing the tooling ball is pushed out due to the air pressure when inserting the tooling ball into the inspection hole to cause an error of inspection To provide a tooling ball.
