Description
本發明是有關於一種加工機的檢知系統與方法，且特別是有關於一種加工機之旋轉中心的檢知系統與方法。The present invention relates to a detection system and method for a processing machine, and more particularly to a detection system and method for a center of rotation of a processing machine.
在一般五軸加工機中，有三個線性軸與兩個旋轉軸。主軸側的運動方向有X軸及Z軸，工作台側的運動方向有Y軸、A軸以及C軸。其中A軸為繞X軸旋轉的方向，C軸為繞Z軸旋轉的方向。In a typical five-axis machine, there are three linear axes and two rotary axes. The movement direction of the main shaft side has an X-axis and a Z-axis, and the movement direction of the table side has a Y-axis, an A-axis, and a C-axis. The A axis is the direction of rotation about the X axis, and the C axis is the direction of rotation about the Z axis.
使用五軸同動加工、四軸同動加工或傾斜面加工等與旋轉軸中心位置有關的功能時，必須將加工機(工作台側)的旋轉中心位置設定在數值控制器內。以使控制器依照旋轉中心的位置來進行旋轉軸與線性軸之間的同動計算。因此，旋轉中心位置量測的準確與否，直接影響到五軸加工機的加工精度。When using a function related to the center position of the rotary shaft, such as five-axis simultaneous machining, four-axis simultaneous machining, or inclined surface machining, the rotation center position of the machining unit (table side) must be set in the numerical controller. In order to make the controller perform the calculation of the same motion between the rotary axis and the linear axis according to the position of the rotation center. Therefore, the accuracy of the measurement of the center position of the rotation directly affects the machining accuracy of the five-axis machining machine.
然而，五軸加工機之工作台側之兩個旋轉軸(A軸和C軸)之實際旋轉中心的位置，常因刀具進刀時撞到被加工的工件或使用者的操作不當而產生偏離，造成與控制器原設定的旋轉中心位置間的偏差。其中，當A軸的實際旋轉中心位置與原設定的旋轉中心位置有誤差時，刀具尖點 在工作台側旋轉後，便會有Y軸方向及Z軸方向的誤差量產生，而此些誤差量會直接影響到被五軸加工機加工之工件的尺寸精度。However, the position of the actual rotation center of the two rotary axes (A-axis and C-axis) on the table side of the five-axis machine often deviates due to the improper operation of the workpiece or the user when the tool enters the tool. , causing a deviation from the original center of rotation of the controller. Wherein, when there is an error between the actual rotation center position of the A-axis and the originally set rotation center position, the tool cusp When the table side is rotated, the amount of error in the Y-axis direction and the Z-axis direction is generated, and the amount of error directly affects the dimensional accuracy of the workpiece processed by the five-axis machining machine.

請參照第1圖與第5圖，第5圖係繪示依照本發明之一實施方式的加工機之旋轉中心的檢知方法的流程圖。首先，安裝圓球體124於工作台102a上(步驟200)，其中工作台102a具有至少一個旋轉軸(例如：A軸和C軸)。接著，安裝量測探頭140於主軸102b朝向圓球體124之一端142(步驟210)，其中主軸102b係設置於工作台102a的上方，並具有朝工作台102a移動之第一線性軸(例如：Z軸)。然後，針對每一個旋轉軸(例如：A軸和C軸)，重複進行一旋轉中心量測步驟220，以獲得每一個旋轉軸的旋轉中心。Referring to FIGS. 1 and 5, FIG. 5 is a flow chart showing a method of detecting the center of rotation of the processing machine according to an embodiment of the present invention. First, the spherical body 124 is mounted on the table 102a (step 200), wherein the table 102a has at least one axis of rotation (for example, an A-axis and a C-axis). Next, the measuring probe 140 is mounted on the main shaft 102b toward one end 142 of the spherical body 124 (step 210), wherein the main shaft 102b is disposed above the table 102a and has a first linear axis that moves toward the table 102a (for example: Z axis). Then, for each of the rotation axes (for example, the A axis and the C axis), a rotation center measurement step 220 is repeatedly performed to obtain the rotation center of each of the rotation axes.
在旋轉中心量測步驟220中，首先，沿著一旋轉軸(例如：A軸或C軸)分別轉動工作台102a至複數個角度(步驟222)。接著，當工作台102a轉動至每一個角度時，重複進行一球心量測步驟300，而獲得分別對應至此些角度之圓球體124的複數個球心座標值。然後，進行一旋轉中心計算步驟400，以根據此些球心座標值來計算出一個旋轉軸的旋轉中心的座標值。In the center of rotation measurement step 220, first, the table 102a is rotated to a plurality of angles along a rotation axis (for example, the A axis or the C axis) (step 222). Next, when the table 102a is rotated to each angle, a center of gravity measurement step 300 is repeated to obtain a plurality of spherical center coordinate values corresponding to the spheres 124 of the angles, respectively. Then, a rotation center calculation step 400 is performed to calculate a coordinate value of the rotation center of one rotation axis based on the spherical center coordinate values.
以下說明球心量測步驟300的流程。The flow of the core measurement step 300 will be described below.
在球心量測步驟300中，移動量測探頭140以碰觸到圓球體124上之至少三個第一位置，而獲得至少三個第一座標值(步驟310)。然後，根據此些第一座標值來計算出圓球體124的球心座標值(步驟320)。圓球體的公式為：(x-a)2 +(x-b)2 +(x-c)2 =R12 (1)In the core measurement step 300, the measurement probe 140 is moved to at least three first positions on the spherical body 124 to obtain at least three first coordinate values (step 310). Then, the spherical center coordinate value of the spherical body 124 is calculated based on the first coordinate values (step 320). The formula for a sphere is: (xa) 2 + (xb) 2 + (xc) 2 = R1 2 (1)
其中(a,b,c)為球心座標值，R1為球半徑。因此，理論上，在獲得圓球體124上之三個位置之座標後，將此三個座標值代入公式(1)便可獲得球心座標值(a,b,c)。然而，解公式(1)需耗費較多的計算時間。因此，本發明另提出一種球心量測步驟，以大幅地縮短計算時間。Where (a, b, c) is the spherical coordinate value and R1 is the spherical radius. Therefore, in theory, after obtaining the coordinates of the three positions on the spherical body 124, the three coordinate values are substituted into the formula (1) to obtain the spherical center coordinate values (a, b, c). However, solving equation (1) requires more computation time. Therefore, the present invention further proposes a spherical core measuring step to greatly shorten the calculation time.

First, the mobile measurement probe 140 touches the four first positions P2, P3, P4, and P5 on the spherical body 124, and obtains four first coordinate values of P2, P3, P4, and P5 and defines a circular shape. Where in an XYZ coordinate system, the first coordinate values are P2(x 2 , y 2 , z 2 ), P3(x 3 , y 3 , z 3 ), P4(x 4 , y 4 , z, respectively 4 ) and P5(x 5 , y 5 , z 5 ), z 2 =z 3 =z 4 =z 5 , the connection of P2 and P4 is parallel to the X-axis, and the connection of P3 and P5 is parallel to the Y-axis. Then, a first calculation step is performed to calculate a center coordinate value Oc(O cx , O cy , O cz ) of the circle according to the following relationship: O cx = (x 2 + x 4 )/2; )
Ocy =(y3 +y5 )/2； (3)O cy = (y 3 + y 5 )/2; (3)
Ocz =z2 =z3 =z4 =z5 。 (4)O cz = z 2 = z 3 = z 4 = z 5 . (4)
接著，移動量測探頭140以碰觸到圓球體124上位於圓心座標Oc(Ocx ,Ocy ,Ocz )之正z軸方向的一第二位置P6，而獲得一第二座標值P6(x6 ,y6 ,z6 )。然後，進行一第二計算步驟，以根據下列關係式來計算出圓球體124的球心座標值O(Ox ,Oy ,Oz )：Ox =Ocx ； (5)Then, the moving measuring probe 140 touches a second position P6 of the spherical body 124 on the positive z-axis direction of the central coordinate Oc (O cx , O cy , O cz ), thereby obtaining a second coordinate value P6 ( x 6 , y 6 , z 6 ). Then, a second calculation step is performed to calculate the spherical coordinate value O(O x , O y , O z ) of the spherical body 124 according to the following relationship: O x = O cx ; (5)
Oy =Ocy ； (6)O y =O cy ; (6)
Oz =z6 -R1 (7)O z =z 6 -R1 (7)
其中R1為圓球體124的半徑。Where R1 is the radius of the sphere 124.
以下說明旋轉中心計算步驟400的流程。The flow of the rotation center calculation step 400 will be described below.
在獲得工作台102a沿著一旋轉軸分別轉動多個角度後之複數個圓球體124的球心座標值，便可根據這些球心座標值來計算出此旋轉軸的旋轉中心的座標值。旋轉中心計算步驟400可分為初步量測步驟和標準量測步驟。初步量測步驟的使用時機是在使用者第一次進行量測時，或者是標準量測步驟無法正常執行完畢時使用，其中初步量測步驟的精確度低於標準量測步驟。以下分別針對A軸或C軸之旋轉中心來說明初步量測步驟和標準量測步驟。After obtaining the spherical coordinate values of the plurality of spheres 124 after the table 102a is rotated by a plurality of angles along a rotation axis, the coordinate value of the rotation center of the rotation axis can be calculated from the spherical center coordinate values. The rotation center calculation step 400 can be divided into a preliminary measurement step and a standard measurement step. The timing of the preliminary measurement step is used when the user performs the measurement for the first time, or when the standard measurement step cannot be performed normally, wherein the accuracy of the preliminary measurement step is lower than the standard measurement step. The preliminary measurement step and the standard measurement step are explained below for the center of rotation of the A-axis or the C-axis, respectively.
當開始量測A軸與C軸旋轉中心座標前，使用者須先對圓球體124(標準圓球)的位置進行第一次的量測。雖然圓球體124可隨使用者的意思任意放置在工作台102a上，但在量測開始時，加工機的A軸必須在0度的位置，且其C軸也要在0度的位置上。至於移動主軸102b來使量測探頭140接觸圓球體124，則可透過適當安排主軸102b的移動路徑來達成。Before starting to measure the center coordinates of the A-axis and the C-axis, the user must first measure the position of the sphere 124 (standard sphere) for the first time. Although the spherical body 124 can be arbitrarily placed on the table 102a as the user desires, at the beginning of the measurement, the A axis of the processing machine must be at a position of 0 degrees, and the C axis thereof must also be at a position of 0 degrees. As for moving the main shaft 102b to bring the measuring probe 140 into contact with the spherical body 124, it can be achieved by appropriately arranging the moving path of the main shaft 102b.
