It relates to a zero point return method according to.
주지된 바와 같이, CNC 공작기계 등과 같이 컴퓨터 수치제어방식의 각종 공작기계에서 절삭가공 공정을 수행하거나 작업 도중 공구를 새롭게 교체할 때에는 기계적인 원점 위치와 제어기내의 좌표계산 기준점을 일치시키기 위한 제로점 조정을 설정해야 하는데, 현재 대부분의 CNC 공작기계에서 이를 수행하기 위해서는 제어패널에 구비된 축 선택바를 조작하여 X축·Y축·Z축을 순차적으로 선택하고, 이후 제로점을 설정하기 위한 '0'키이 및 입력버튼(Input Button)을 눌러 제로점을 복귀시켰다.As is well known, when performing a cutting process on various machine tools of a computer numerical control method such as a CNC machine tool or when a tool is newly replaced during operation, zero point adjustment is made to match the mechanical reference point and the coordinate calculation reference point in the controller. In order to do this in most CNC machine tools, the axis selection bar provided in the control panel is used to select the X, Y, and Z axes in sequence, and then the '0' key for setting the zero point. And the Input Button were pressed to reset the zero point.
그런데, 상기와 같은 제로점 설정작업은 작업자가 X축·Y축·Z축의 각각을 선택하기 위한 축 선택바를 조정한 후 키이패드중 ZERO버튼 및 입력버튼(Input button)을 순차적으로 입력하기 때문에 버튼 조작의 번거로운 점이 있었다. 이는 작업자가 절삭공정 수행시에 통상 장갑 등을 착용한 채 작업을 하기 때문에 버튼 입력시 누르고자 하는 버튼 이외의 버튼이 조작될 염려가 있어 작업시간이 지체되는 것을 초래하게 되는 문제점이 있었다.However, in the zero point setting operation as described above, since the operator adjusts the axis selection bar for selecting each of the X, Y, and Z axes, the ZERO button and the Input button of the keypad are sequentially input.

Figure is a view showing a state in which the identification code generating pad is provided to recognize the identification code.
이에 도시된 바와 같이, 일반적인 CNC 밀링머신의 제어패널에 제로점복귀단축버튼(100)을 장착시키는 바, 그 제로점복귀단축버튼(100)은 통상적으로 제공되는 X축·Y축·Z축뿐만 아니라 4차원, 5차원적인 가공물에 대한 절삭가공시에 그에 대응되는 제로리턴스위치의 개수만큼 제로점복귀단축버튼이 구성된다.As shown in the figure, a zero point return short button 100 is mounted on a control panel of a general CNC milling machine, and the zero point return short button 100 is normally provided only with X, Y, and Z axes. Rather, the zero point return button is configured as many times as the number of zero return switches corresponding to the four-dimensional and five-dimensional workpieces.
그리고, 상기 제로점복귀단축버튼(100)이 조작되었을 때 마이크로프로세서 (120)가 어느 축에 대한 단축버튼인지를 인지할 수 있도록 각각의 단축버튼에 대한 식별코드를 발생하는 식별코드발생패드(110)와, 상기 식별코드발생패드(110)에서 발생된 식별코드와 기 설정된 식별코드를 비교한 후 어느 축에 대한 단축버튼인지를 판단하는 마이크로프로세서(120) 및, 상기 마이크로프로세서(120)의 제어동작에 따라 상기 조작된 단축버튼에 대한 제로점 복귀를 실행하는 제로점복귀프로그램 (130)으로 구성된다.And, when the zero point return shortcut button 100 is operated, the identification code generation pad 110 for generating an identification code for each shortcut button so that the microprocessor 120 can recognize the shortcut button for which axis And a microprocessor 120 for determining which axis is a shortcut button after comparing the identification code generated by the identification code generating pad 110 with a predetermined identification code, and control of the microprocessor 120. The zero point return program 130 executes zero point return for the operated shortcut button according to the operation.
여기서, 상기 식별코드발생패드(110)는 제로점 복귀 단축버튼(100)의 하방향에 장착되며, 어느 하나의 단축버튼이 눌려지면 식별코드발생패드(110)의 대응되는 부분으로부터 소정 식별코드가 발생되는 구성을 갖는다.Here, the identification code generation pad 110 is mounted in the downward direction of the zero point return shortcut button 100, and when any one of the shortcut buttons is pressed, a predetermined identification code is generated from a corresponding portion of the identification code generation pad 110. It has a generated configuration.
그와 같이 제어패널상에 구성된 제로점 복귀 단축버튼이 조작되었을 때 제로점으로 복귀되는 과정을 도 1내지 도 3을 참조하여 설명하기로 한다.The process of returning to the zero point when the zero point return shortcut button configured on the control panel is operated will be described with reference to FIGS. 1 to 3.
먼저, CNC 밀링머신을 이용하여 소정 밀링 가공작업을 수행하는 도중에, 밀링공구가 파손되어 새 밀링공구로 교체 하거나, 또는 피가공물에 대한 어느 하나의 공정이 완료된 후에는, 반드시 축의 좌표값에 대해 제로점 복귀명령을 수행해야 하는바, 모든 축에 대한 제로점 복귀를 위해 작업자가 제어패널에 구비된 제로점복귀 단축버튼(100)을 조작한다(단계200).First, during a certain milling operation using a CNC milling machine, the milling tool is broken and replaced with a new milling tool, or after any one process for the workpiece is completed, always zero to the coordinate value of the axis. As a point return command should be performed, the operator operates the zero point return shortcut button 100 provided in the control panel to return the zero point to all axes (step 200).
그와같이 단축버튼(100)이 조작되면, 그 단축버튼(100)의 하방향에 구비된 식별코드발생패드(110)는 조작된 단축버튼의 접촉에 따라 소정 식별코드를 발생하게 된다. 예를 들어 설명하면, X축에 대한 단축버튼이 눌러지면 '001'의 식별코드가 발생되고, Y축 및 Z축 단축버튼이 눌러지면 '010', '011'과 같은 식별코드가 발생되는 것이다. 물론, 상기 식별코드에 대한 정의, 예컨대 'X축-001, Y축-010, Z축-011'와 같이 각각의 축에 대한 식별코드는 소정 메모리(도면 미도시)에 기 설정되어 저장되어 있다(단계210).As such, when the shortcut button 100 is operated, the identification code generation pad 110 provided in the downward direction of the shortcut button 100 generates a predetermined identification code according to the contact of the operated shortcut button. For example, when the shortcut button for the X axis is pressed, an identification code of '001' is generated, and when the Y and Z axis shortcut buttons are pressed, identification codes such as '010' and '011' are generated. . Of course, the definition of the identification code, for example, the identification code for each axis, such as 'X axis-001, Y axis-010, Z axis-011' is pre-set and stored in a predetermined memory (not shown) (Step 210).
그에 따라, 만약 X축 단축버튼이 눌려지면 식별코드발생패드(110)로부터 '001'의 식별코드가 발생되어 마이크로프로세서(120)로 인가되며(도 2참조), 그 마이크로프로세서(120)는 소정 메모리에 기억된 식별코드와의 비교에 따라 현재 눌러진 단축버튼이 X축 단축버튼임을 확인한다.Accordingly, if the X-axis shortcut button is pressed, an identification code of '001' is generated from the identification code generating pad 110 and applied to the microprocessor 120 (see FIG. 2), and the microprocessor 120 is predetermined. According to the comparison with the identification code stored in the memory, confirm that the currently pressed shortcut button is the X axis shortcut button.
이후, 마이크로프로세서(120)의 제어신호에 따라 제로점복귀프로그램(130)이 액세스되고, 그 제로점복귀프로그램(130)의 명령 수행에 따라 상기 조작된 단축버튼에 대한 축의 좌표값을 제로점으로 복귀시키게 된다(단계 220, 230). 상기 제로점은 CRT에 표시되어 이를 확인할 수 있게 한다(단계 240).Thereafter, the zero point return program 130 is accessed according to the control signal of the microprocessor 120, and the coordinate value of the axis for the operated shortcut button is zero as the command of the zero point return program 130 is executed. It is returned (steps 220 and 230). The zero point is displayed on the CRT to confirm this (step 240).
그러나, 에러발생으로 인해 제로점 복귀가 실행되지 않으면(단계 230에서 아니오), 상기 에러발생상태를 CRT에 표시하고(단계 250), 만약 작업자가 다시 단축버튼을 조작하게 되면 상기 단계 200으로 복귀되어 전술한 과정을 반복하게 된다(단계 260).However, if the zero point return is not executed due to an error (NO in step 230), the error occurrence state is displayed on the CRT (step 250), and if the operator operates the shortcut button again, the process returns to step 200. The above process is repeated (step 260).
즉, 본 발명은 제어패널에 별도 제공된 제로점복귀단축버튼을 조작하면 그 조작된 제로점복귀단축버튼이 어느 축에 대한 단축버튼인지를 판단한 후 해당 축 좌표값을 제로점으로 복귀시키게 된다.That is, in the present invention, when the zero point return short button is separately provided to the control panel, it is determined whether the operated zero point return short button is a shortcut button and the corresponding axis coordinate value is returned to the zero point.
한편, 상기에서는 제로점 복귀를 위한 단축버튼이 X축,Y축, Z축 등과 같이 각각 제공된 상태에서 설명하였지만, 하나의 제로점복귀단축버튼만을 제공한 상태에서 그 단축버튼이 눌러졌을 때 한번에 모든 축에 대해 축 좌표값을 제로점으로 복귀할 수 있도록 상기 제로점복귀프로그램을 재설정할 수 있다.Meanwhile, in the above, the shortcut buttons for returning to the zero point have been described in the state of being provided such as the X axis, the Y axis, and the Z axis, respectively, but when the shortcut button is pressed in the state where only one zero point return shortcut button is provided, all The zero point return program can be reset to return the axis coordinate values to the zero point for the axis.
즉, 도 4와 같이 하나의 제로점복귀단축버튼이 조작되면 제로점복귀프로그램에 저장된 명령에 의해 제어패널에 제공된 축의 좌표값을 순차적으로 제로점으로 복귀시키는바, X축에 대한 제로점을 복귀시킨 후 Y축, Z축에 대한 제로점을 순서대로 복귀시킬 수 있는 것이다(단계 300 내지 단계 320).That is, when one zero point return short axis button is operated as shown in FIG. 4, the coordinate values of the axes provided to the control panel are sequentially returned to the zero points by the command stored in the zero point return program, and the zero point for the X axis is returned. After that, the zero points for the Y and Z axes can be returned in order (steps 300 to 320).
이상에서 설명한 바와 같이, 본 발명에 따르면 제로점복귀단축버튼이 별도 제공된 상태에서 그 단축버튼 조작시 해당 축에 대한 좌표값을 프로그램명령에 따라 자동으로 복귀시킬수 있음으로써, 종래 기술에 비해 제로점 복귀 과정이 보다 간단하게 진행되어 작업능률을 향상시킬수 있는 효과가 있다.As described above, according to the present invention, when the zero point return short cut button is separately provided, the coordinate value for the corresponding axis can be automatically returned according to the program command when the shortcut button is operated, and thus, the zero point return is compared with the prior art. The process is made simpler, which has the effect of improving work efficiency.
