본 발명은 레이저 가공기 또는 가스절단기에 취부된 트레이싱 장치를 이용한 피어싱 제어방법에 관한 것으로서, 특히 가공소재 표면에 접촉되는 접촉감지부재를 가공노즐과 분리설치하여 피어싱 가공시 상승시키므로서 스패터의 퇴적으로 인한 작업불량을 효율적으로 방지할 수 있는 트레이싱 장치를 이용한 피어싱 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piercing control method using a tracing device attached to a laser processing machine or a gas cutting machine. In particular, a contact sensing member contacting a surface of a workpiece is separated from a processing nozzle and raised during piercing processing. The present invention relates to a piercing control method using a tracing device that can effectively prevent a malfunction caused by the work.
종래에는 레이저 가공기나 가스절단기에 의해서 절단가공을 수행함에 있어서, 먼저 가공노즐의 선단에 링형의 접촉감지부를 구비하고, 상기 가공노즐을 수치제어에 의해 피가공물의 표면에 소정의 간격으로 접근시켜 레이저 빔을 조사함으로써 피어싱 가공을 완료하였다. 여기서, 피어싱 가공이라함은 레이저를 조사하여 피가공물을 절단하기에 앞서 재료의 표면에 구멍을 뚫는 공정을 말한다. 이렇게 피어싱 가공이 완료된후 가공노즐 이송축에 의해 가공노즐을 이송하여 가며 절단가공을 수행하였다.Conventionally, in performing cutting by a laser processing machine or a gas cutting machine, first, a ring-shaped contact sensing unit is provided at the tip of the processing nozzle, and the processing nozzle is approached to the surface of the workpiece at a predetermined interval by numerical control to laser the laser. Piercing processing was completed by irradiating the beam. Here, the piercing processing refers to a process of drilling a hole in the surface of the material prior to cutting the workpiece by laser irradiation. After the piercing process is completed, the cutting nozzle was moved by moving the processing nozzle by the processing nozzle feed shaft.
이러한 종래의 절단가공을 첨부도면 제1도를 참조하여 구체적으로 살펴보면 다음과 같다. 여기서, 제1도는 종래의 절단가공 동작제어에 관한 플로우챠트를 나타내는 것이다.Looking at such a conventional cutting process in detail with reference to the accompanying drawings, Figure 1 as follows. Here, FIG. 1 shows a flowchart relating to the conventional cutting operation control.
사이클 스타트[단계 S10]에 의해 높이 제어 온(ON)상태로 구동되는 구동모터를 동작하고[단계 S11], 상기 구동모터에 의해 이송되는 가공노즐의 이송량을 검출하여 이를 설정된 량과 비교 판단하므로써 가공노즐의 이송을 완료시키고[단계 S12], 상기에서 가공노즐의 이송이 완료되면 레이저 빔이 조사되어 피어싱 가공을 수행하고[단계 S13], 피어싱의 가공이 종료되면 각 이송축을 제어하여 절단가공을 수행하고[단계 S14], 절단가공이 완료되면 각 축의 이송을 정지하고[단계 S15], 높이 제어를 오프(OFF)하고[단계 S16], Z측 이송을 실시하고[단계 S17], 가공노즐 이송을 종료[단계 S18]하게 된다.The driving motor driven in the height control ON state by the cycle start [step S10] is operated [step S11], and the machining is performed by detecting the feed amount of the machining nozzle fed by the drive motor and comparing it with the set amount. When the transfer of the nozzle is completed (step S12), and the transfer of the machining nozzle is completed in the above, the laser beam is irradiated to perform piercing processing [step S13]. [Step S14], when the cutting is completed, the feed of each axis is stopped [Step S15], the height control is turned off [Step S16], the Z-side feed is performed [Step S17], and the machining nozzle feed is performed. It ends (step S18).
이러한, 종래의 절단 가공법에 있어서는 절단가공을 하기전에 행하는 피어싱에 있어 발생되는 스패터가 접촉감지부와 피가공소재의 사이에 쌓이게 되어 다음동작 즉, 가공노즐이 절단동작으로 이송될시에 방해가 되고 그 간격이 변하게 되어 품질 불량의 원인이 된다. 또, 스패터는 그 자체로도 가공물의 소재에 잔존하게 되므로 품질불량이 되는 문제점이 있다.In such a conventional cutting method, spatters generated in the piercing before cutting are accumulated between the contact sensing unit and the workpiece to prevent the next operation, that is, when the processing nozzle is transferred to the cutting operation. The gap is changed, which causes quality defects. In addition, the spatter is left in the material of the workpiece itself, there is a problem that becomes poor quality.
본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 창안된 것으로서, 본 발명의 목적은 가스절단기나 레이저가공기의 피어싱 작업시 발생하는 스패터가 피가공물의 표면과 접촉감지부 사이에 퇴적되는 것을 방지하고 가공노즐의 선단과 가공소재 표면 사이의 거리를 일정한 간격으로 유지할 수 있는 트레이싱 장치를 이용한 피어싱 제어방법을 제공함에 있다.The present invention has been made to solve the above problems of the prior art, an object of the present invention is that the spatter generated during the piercing operation of the gas cutting machine or the laser processing machine is deposited between the surface of the workpiece and the contact sensing unit. The present invention provides a piercing control method using a tracing device that can prevent and maintain the distance between the tip of the processing nozzle and the surface of the workpiece at regular intervals.
상기와 같은 목적을 달성하기 위한 본 발명의 피어싱 제어방법은 솔레노이드의 흡착에 의해 접촉감지부재를 하강시켜 가공소재의 표면에 접촉시키는 단계와, 상기 접촉감지부재의 접촉이 완료되면 수치제어에 따라 구동모터를 작동시킴으로써 가공노즐의 선단과 피가공소재 표면 사이의 설정간격을 조절하는 단계와, 상기 가공노즐의 설정간격이 최적의 상태에 도달한후 상기 솔레노이드에 가해지는 전압을 차단하므로써 상기 접촉감지부재를 원래의 위치로 상승시키는 단계 및 사기 접촉감지부재가 상승된후 상기 가공노즐에서 레이저 빔이 조사되어 가공소재 표면에 피어싱을 실시하는 단계로 이루어진다.The piercing control method of the present invention for achieving the above object is a step of contacting the surface of the workpiece by lowering the contact sensing member by the adsorption of the solenoid, and driving under numerical control when the contact sensing member is completed Adjusting the set interval between the tip of the machining nozzle and the surface of the workpiece by operating a motor; and blocking the voltage applied to the solenoid after the set interval of the machining nozzle reaches an optimum state. Is raised to its original position and the laser beam is irradiated from the processing nozzle after the fraud contact sensing member is raised to pierce the surface of the workpiece.
이하에서는 첨부도면 제2도 및 제3도를 참조하므로써 본 발명의 피어싱 제어방법이 실현되는 구체적 수단 및 그 실행과정을 구체적으로 살펴보도록 하겠다. 여기서, 제2도는 본 발명에 적용되는 트레이싱 장치가 노즐헤드부에 취부된 상태를 도시한 것이고, 제3도는 본 발명에 따른 가공동작 제어에 관한 플로우챠트를 나타내는 것이다.Hereinafter, with reference to the accompanying drawings 2 and 3 will be described in detail the specific means and the implementation process of the piercing control method of the present invention. Here, FIG. 2 shows a state in which the tracing apparatus applied to the present invention is mounted on the nozzle head portion, and FIG. 3 shows a flowchart relating to the machining operation control according to the present invention.
제2도에 도시된 바와 같이, 가스절단기 또는 레이저 가공기의 가공헤드부(10) 하단부에는 가공노즐(11)이 부착되어 피어싱 작업시 레이저 빔을 조사하고 상기 가공헤드부(10)의 측단에는 트레이싱 장치(30)가 취부되어 있다. 또한, 상기 가공노즐(11)의 선단부에는 링형의 접촉감지부가 지지부재에 지지된채 상기 트레이싱 장치의 솔레노이드(38) 상단에 부착되어 접촉감지부재(36)를 형성하고 상기 트레이싱 장치(30)의 하우징 내부에는 상기 접촉감지부재(36)를 전자력에 의해 흡착하고 복귀시킴으로서 상,하 이동시키는 솔레노이드(38)가 내장되어 있다. 또한, 상기 트레이싱 장치(30)의 하우징 내부에는 가공노즐(11)과 피가공 소재 표면 사이에 최적의 설정간격에 대응하는 전압을 인가하는 전압가변기(34)가 내장되어 있다.As shown in FIG. 2, a processing nozzle 11 is attached to a lower end of the processing head 10 of a gas cutter or a laser processing machine to irradiate a laser beam during a piercing operation, and tracing at a side end of the processing head 10. The device 30 is mounted. In addition, the front end of the processing nozzle 11 is attached to the upper end of the solenoid 38 of the tracing device while the ring-shaped contact sensing portion is supported by the support member to form a contact sensing member 36 and the tracing device 30 Inside the housing, a solenoid 38 for moving up and down by adsorbing and returning the contact sensing member 36 by an electromagnetic force is incorporated. In addition, a voltage transformer 34 for applying a voltage corresponding to an optimum setting interval between the processing nozzle 11 and the workpiece surface is embedded in the housing of the tracing device 30.
따라서, 상기한 트레이싱 장치(30)를 취부한 가스절단기 또는 레이저 가공기의 피어싱 작업은 아래와 같은 동작으로 이루어진다. 피어싱 작업 개시명령에 따라 상기 트레이싱장치 내부의 솔레노이드(38)에 전압이 인가되고 상기 솔레노이드에 전자력이 발생하여 접촉감지부재(36)를 흡착시킴으로써 접촉감지부재는 하강하여 피가공 소재의 표면에 접촉하게 된다. 이렇게 접촉감지부재의 접촉이 완료되면 상기 전압가변기(34)에 인가된 전압에 대응하는 설정간격에 따라 구동모터가 작동하므로써 가공노즐(11)이 최적의 설정간격을 이루는 지점으로 높이를 조절한다. 가공노즐의 높이의 조절이 완료되면 상기 솔레노이드에 가해진 전압이 끊어지면서 솔레노이드의 전자력이 상실되어 접촉감지부재는 위로 상승하게 된다. 접촉감지부재가 위로 상승된 후 가공노즐에서 레이저 빔이 조사됨으로서 가공소재에 대한 피어싱 작업이 수행된다. 이 경우 피어싱 작업중 발생하는 스패터(spatter)가 접촉감지부재와 가공소재표면 사이에 퇴적될 염려가 없어 이로인한 제품의 부량 및 접촉감지부재와 가공노즐의 손상을 방지할 수 있다.Therefore, the piercing operation of the gas cutting machine or the laser processing machine in which the tracing device 30 is mounted is performed as follows. A voltage is applied to the solenoid 38 inside the tracing device according to the piercing operation start command and an electromagnetic force is generated in the solenoid to absorb the contact sensing member 36 so that the contact sensing member is lowered to contact the surface of the workpiece. do. When the contact of the contact sensing member is completed as described above, the driving motor operates according to the setting interval corresponding to the voltage applied to the voltage variable valve 34, thereby adjusting the height to the point where the machining nozzle 11 achieves the optimum setting interval. When the adjustment of the height of the processing nozzle is completed, the voltage applied to the solenoid is cut off and the electromagnetic force of the solenoid is lost, and the contact sensing member is raised upward. After the contact sensing member is lifted up, the laser beam is irradiated from the processing nozzle to perform a piercing operation on the workpiece. In this case, the spatter generated during the piercing operation may not be deposited between the contact sensing member and the surface of the workpiece, thereby preventing the quantity of the product and the damage of the contact sensing member and the processing nozzle.
상기한 과정을 첨부도면 제3도를 통해 보다 상세하게 살펴보면 다음과 같다. 먼저, 가공기를 기동하는 사이클 스타트 단계[단계 S10]를 통하여 접촉부재가 요구된 위치로 다운되었는지를 비교판단하고[단계 S10-1], 접촉부재가 요구된 위치로 다운되지 않았을 때[단계 S10-2]를 거쳐 높이 제어 온(ON)에 따라 Z축 이송을 실시하고[단계 S12], 상기 단계에서의 설정간격 제어가 완료되면[단계 S12-1]를 통해 높이 제어 오프(OFF)로 Z축 이송을 정지하고, [단계 S12-2]에 의해 접촉감지부재를 상승으로 퇴피시키고, [단계 S13]을 통해 가공노즐에 레이저 빔을 조사하여 피어싱 가공을 완료하고, 다시 [단계 S13]을 통해 접촉감지부재를 다운하여 높이 제어 온(ON)상태로 하고, [단계 S14]를 통해 각 이송축의 이송으로 절단가공을 진행하고, [단계 S15]를 통해 가공완료되면 축 이송을 정지한다.The above process will be described in more detail with reference to FIG. 3 as follows. First, a comparison is made as to whether or not the contact member is down to the required position through the cycle start step (step S10) of starting the machine, and when the contact member is not down to the required position [step S10-. 2] Z-axis feed is carried out in accordance with the height control ON [step S12], and when the setting interval control in the above step is completed [step S12-1], the Z-axis to the height control OFF (step) The transfer is stopped, the contact sensing member is retracted by the rising by [Step S12-2], the laser beam is irradiated to the processing nozzle through [Step S13] to complete the piercing process, and the contact is again made through [Step S13]. The sensing member is turned down to the height control ON state, the cutting process is performed by the feed of each feed shaft through [Step S14], and the axis feeding is stopped when the processing is completed through [Step S15].
상술한 바와같이 본 발명에 의하면 피어싱시 접촉감지부재의 보호가 가능하고 접촉감지부재에 의한 스패터 자국을 없앨 수가 있어 고품질의 가공물을 얻을 수가 있다.As described above, according to the present invention, it is possible to protect the contact sensing member during piercing and to eliminate the spatter marks caused by the contact sensing member, thereby obtaining a high-quality workpiece.
