스윙암 방식이 큐세터(Q-Setter) 위치보상방법Swing-arm method is Q-Setter position compensation method

도면은 본 발명의 큐세터 위치보상방법을 수행하는 플로우 챠트이다.Figure is a flow chart for performing the cusetter position compensation method of the present invention.

본 발명은 NC선반의 공구위치를 측정하는 스윙암방식의 큐세터 위치보상방법에 관한 것이다.The present invention relates to a swing arm type cusetter position compensation method for measuring the tool position of the NC lathe.

종래에는 큐세터 아암을 하강시킨 후 사용공구의 오프셋을 측정하여 자동입력시키나, 스윙암방식의 하강위치는 주변환경에 따라 항상 일정하지 않고 또한, 볼 스크류의 열변위 및 유압과 유온의 차이에 의해서 위치정도가 변하므로 공구팁 마모량을 측정하여 자동입력하여 가공을 행하면 가공물은 불량일 경우가 매우 높다.Conventionally, the offset of the tool is automatically inputted after lowering the cusetter arm, but the swinging position of the swing arm method is not always constant depending on the surrounding environment. Since the accuracy of the position changes, if the tool tip wear is measured and automatically entered and processed, the workpiece is very bad.

본 발명의 목적은 상기와 같은 단점을 제거하기 위하여 큐세터 아암을 하강시킨 후 마스터 툴의 위치를 측정하고, 다음에 사용공구의 오프셋 값을 측정하여 정도보상 값을 자동입력하는 스윙암 방식의 큐세터 위치보상방법을 제공하고자 하는 것이다.An object of the present invention is to swing the cusetter arm in order to eliminate the above-mentioned disadvantages, and then to measure the position of the master tool, and then to automatically input the accuracy compensation value by measuring the offset value of the tool used. It is to provide a setter position compensation method.

상기 목적을 달성하기 위해 본 발명은 NC선반의 스윙암방식의 큐세터 위치보상방법에 있어서, 큐세터가 하강한 후에 마스터 툴의 X축값을 측정하여 오차범위내에 있으면 다음단계를 수행하고 그렇지 않으면 경보하고 디스플레이하는 단계(A), 상기 마스터 툴의 X축값이 오차범위내에 있으면 마스터 툴의 Z축값을 측정하고 다음 단계를 수행하며 그렇지 않으면 경보하고 디스플레이하는 단계(B), 상기 마스터 툴의 Z축값이 오차범위내에 있으면 실제 사용공구의 X축값을 측정하여 상기 마스터 툴의 X축 오프셋 값에 정도보상하고 다음 단계를 수행하며 그렇지 않으면 경보하고 디스플레이하는 단계(C), 실제 사용 공구의 Z축 값을 측정하여 상기 실제 사용공구의 Z축값이 오차범위내에 있으면 마스터 툴의 Z축 오프셋 값을 정도보상하고 그렇지 않으면 경보하고 디스플레이하는 단계(D)로 이루어지는 것을 특징으로 한다.In order to achieve the above object, the present invention, in the swing arm type cusetter position compensation method of the NC lathe, measures the X-axis value of the master tool after the cusetter descends and performs the following steps if it is within the error range, otherwise the alarm (A), if the X axis value of the master tool is within the error range, measure the Z axis value of the master tool and perform the next step; otherwise, alarm and display (B), the Z axis value of the master tool If it is within the error range, measure the X-axis value of the actual tool, compensate for the X-axis offset value of the master tool, perform the following steps, otherwise alarm and display (C), measure the Z-axis value of the actual tool If the Z axis value of the actual tool is within the error range, compensate the Z axis offset value of the master tool. It characterized by comprising the step (D) for displaying.

본 발명은 첨부된 도면을 참조하여 상세하게 설명한다.The invention will be described in detail with reference to the accompanying drawings.

도면에는 본 발명이 큐세터 위치보상방법이 플로우 챠트로 도시되어 있다.In the drawings, the present invention shows a cusetter position compensation method in a flow chart.

(A)단계에서는, 큐세터가 하강된 후에 측정센서를 이용하여 마스터툴의 X축값을 측정하고, 상기 마스터 툴의 X축값의 절대값이 오차범위내에 있으면 다음 단계를 수행하도록 하고, 오차범위보다 크면 경보를 울리고 오프셋값 과다를 디스플레이 한다.In the step (A), after the cusetter is lowered, the X-axis value of the master tool is measured by using a measuring sensor, and if the absolute value of the X-axis value of the master tool is within the error range, the next step is performed. If it is big, it will sound an alarm and display excessive offset value.

(B)단계에서는, 상기 (A)단계에서 측정한 마스터 툴의 X축값의 절대값이 오차범위내에 있으면 마스터 툴의 Z축값을 측정하고, 이 마스터툴의 Z축값의 절대값이 오차범위내에 있으면 다음 단계를 수행하도록 하고, 오차범위보다 크면 경보를 울리고 오프셋 값 과다를 디스플레이 한다.In step (B), if the absolute value of the X axis value of the master tool measured in step (A) is within the error range, the Z axis value of the master tool is measured, and if the absolute value of the Z axis value of the master tool is within the error range, Perform the following steps, and if it is larger than the error range, sound an alarm and display excessive offset value.

(C)단계에서는, 상기 (B)단계에서 측정한 마스터 툴의 Z축값의 절대값이 오차범위보다 작으면 실제사용공구의 X축값을 측정하고, 마스터 툴의 X축 오프셋 값에 이 값을 더하여 정도보상을 하며, 정도보상의 절대값이 오차범위보다 크면 경보를 울리고, 오프셋 값 과다를 디스플레이 한다.In the step (C), if the absolute value of the Z axis value of the master tool measured in the step (B) is smaller than the error range, the X axis value of the actual tool is measured, and this value is added to the X axis offset value of the master tool. If the absolute value of the accuracy compensation is greater than the error range, an alarm is sounded and the offset value is excessively displayed.

(D)단계에서는, 실제 사용 공구의 Z축값을 측정하고, 마스터 툴의 Z축 오프셋 값에 이 값을 더하여 정도보상을 하며, 정도보상의 절대값이 오차범위보다 크면 경보를 울리고, 오프셋 값 과다를 디스플레이 한다. 정보보상의 절대값이 오차범위내에 있으면 이 값을 Z축값에 입력한다.In the step (D), the Z axis value of the actual tool is measured, and the compensation is performed by adding this value to the Z axis offset value of the master tool.If the absolute value of the accuracy compensation is larger than the error range, an alarm is sounded and the offset value is excessive. Is displayed. If the absolute value of the information compensation is within the error range, enter this value in the Z-axis value.

상기의 큐세터의 위치보상에 대한 오차범위는 스윙암에 부착되어 있는 센서 자체의 오+CNC에서 신호 처리하기까지의 지연시간 오차+스윙암등에서 발생될 수 있는 기계적인 오차 등을 합친 값이다.The error range of the position compensation of the cue setter is a sum of the mechanical error that may occur in the delay time error until the signal processing by the error + CNC of the sensor itself attached to the swing arm + swing arm.

상기와 같은 본 발명의 큐세터 위치보상방법은 마스터 툴의 위치를 측정하고 실제사용공구의 오프셋값을 정도보상하여 스윙암 방식의 큐세터 위치변화에 대한 고려가 이루어지므로 보상값에 의한 정확한 입력으로 가공물의 불량을 줄이는 효과를 제공한다.As described above, the cusetter position compensation method of the present invention measures the position of the master tool and compensates the offset value of the actual tool, thereby considering the swing arm type cusetter position change. It provides the effect of reducing the defect of the workpiece.
