Abstract

The cutting locus of a cutter in a wood working machine is calculated by the coordinate value of the vertical cutting locus, which cuts the wood from front to rear or from right to left, and the horizental cutting locus, which cuts from up to down. The center of the shaft spindle moves in any direction. A microcomputer calculates the coordinate value of the cutting locus by an input value from the rotating radius of the shaft spindle. The cutters always cut the wood plane vertically on this locus. This calculated value improves the processing work.

본 발명은 목공기계에 관하여, 특히 가공면을 곡면형상으로 절삭하는 절삭방법에 관한 것이다.TECHNICAL FIELD The present invention relates to a woodworking machine, and more particularly, to a cutting method for cutting a machining surface into a curved shape.

종래에 있어서, 목공기계에 의하여 가공재의 표면을 입체적으로 절삭하는 경우 칼날부분은 가공면에 대하여 수직적으로 상하하는 것뿐이므로 곡면에 단차(段差)가 생겨서 곡면형상으로 아름답게 절삭할 수가 없었다.In the prior art, when the surface of a workpiece is three-dimensionally cut by a woodworking machine, since the blade portion is only vertically up and down with respect to the processing surface, a step is generated on the curved surface, so that the cutting surface cannot be cut beautifully.

본 발명은 절삭부분에 적응한 복수의 칼날부분의 각각 그것에 대하여 이 칼날부분이 피가공물에 대해서 전후 좌우방향으로 절삭, 즉 피가공물의 수직면 절삭이동하는 궤적도와, 그 이동에 따라서 상하방향으로 절삭, 즉 피가공물의 수평면 절삭이동하는 궤적도와의 좌표값에 의하여 칼날부분의 절삭이동궤적을 연산하고, 여기에 칼날부분을 부착한 주축 스핀들의 중심이 피가공물에 대하여 전후. 좌우. 상하방향으로 이동하며, 또한 전기한 주축스핀들이 선회각도 이동가능한 가공기의 전기한 선회반지름을 데이터 입력하는 것에 의하여 가공기에 배설한 전기한 칼날 부분이 항상 가공면에 대하여 수직(직각)으로 위치하면서 절삭이동하는 궤적의 좌표값을 마이크로컴퓨터에 의하여 연산하고, 이 수치에 의하여 전기한 가공기를 작동하여서 복합적인 곡면을 절삭하는 것이다.According to the present invention, a plurality of blade portions adapted to the cutting portion are cut in the front, rear, left, and right directions with respect to the workpiece, that is, the trajectory of cutting the vertical plane of the workpiece, and cutting in the vertical direction according to the movement. In other words, the cutting movement trajectory of the blade part is calculated based on the coordinate value of the trajectory diagram of the cutting plane of the workpiece, and the center of the spindle spindle with the blade part attached to the workpiece. Right and left. By inputting data of the turning radius of the machine, which moves up and down and the spindle spindles can also move the turning angle, the cut edge placed on the cutting machine is always cut perpendicular to the machining surface. The coordinate value of the moving trajectory is calculated by a microcomputer, and the complex machine is cut by operating the machine described by the numerical value.

본 발명은 수직면의 절삭이동궤적과, 수평면의 절삭이동궤적과의 좌표값에 의하여 칼날부분의 절삭이동 궤적을 연산하고, 칼날부분을 전후. 좌우. 상하방향으로 이동시켜서 칼날부분을 부착한 주측스핀들이 선회이동 가능한 가공기의 선회반지름을 데이터 입력하여, 칼날부분을 항상 가공면에 대하여 직각으로 위치하면서 절삭하는 궤적의 좌표값을 마이크로 컴퓨터에 의하여 연산하고, 이들의 수치로서 가공기를 작동시키는 곡면절삭방법이다.The present invention calculates the cutting movement trajectory of the blade portion based on the coordinates of the cutting movement trajectory of the vertical plane and the cutting movement trajectory of the horizontal plane, before and after the blade portion. Right and left. By inputting the turning radius of the machine where the main spindles attached to the blade part can be pivoted by moving up and down, the micro coordinates calculate the coordinate value of the trajectory that cuts the blade part at right angles to the machining surface. This is a curved cutting method for operating the machine with these numerical values.

본 발명의 방법을 실시하는 1예로서 목공용 루우터기계는 제1도에 표시하는 바와 같이 좌표판독기(1), 마이크로 컴퓨터(2), NC테이프작성기(3), NC 장치(4), 가공기(5)를 갖추고, 가공기(5)는 칼날부분을 회동하는 모우터를 방사상으로 배설한 헤드(6)와, 이 헤드(6)를 선회하는 서어보모우터(7)를 배설한 지지체(8)와, 지지체(8)의 상하작동용 서어보모우터(9)를 설치한 접동체(10) 및 접동체(10)의 좌우작동용 서어보모우터(11) 및, 피가공물(W)을 재치고정한 테이블(T)의 전후작동용 서어보모우터(12)에 의하여 구성되어 있다.As an example of implementing the method of the present invention, a woodworking router machine includes a coordinate reader (1), a microcomputer (2), an NC tape maker (3), an NC device (4), a processing machine, as shown in FIG. (5), the processing machine (5) has the head (6) which radially provided the motor which rotates the blade part, and the support body (8) which provided the servo motor (7) which turns this head (6). And the sliding body 10 provided with the servomotor 9 for vertical operation of the support body 8, the servomotor 11 for left and right operation of the sliding body 10, and the workpiece W It is comprised by the servo motor 12 for back and front operation | movement of the table T.

그리고 칼날부분(M3)이 피가공물(W)에 대하여 전후, 좌우방향으로 절삭이동하는 궤적을 표시하는 평면도(제2(a)도)와 그 이동에 따라서 상하방향으로 절삭이동하는 궤적을 표시하는 단면도(제2(b)도)를 좌표판독기(1)에 설치하고, 전기한 평면도 궤적을 x, y 좌표로서, 단면도 궤적을 x, z 좌표로서 가공순서에 따라 그 좌표값을 판독하며, 이 수치를 마이크로컴퓨터(2)에 입력한다.In addition, a plan view (second (a) diagram) showing the trajectory of the cutting edge M 3 cutting back and forth and the left and right directions with respect to the workpiece W and the trajectory of the cutting movement in the vertical direction in accordance with the movement are shown. A cross sectional view (second (b)) is installed in the coordinate reader 1, and the coordinate values are read out according to the processing order as the plan view trajectory as the x and y coordinates and the cross sectional trajectory as the x and z coordinates. This value is input to the microcomputer 2.

마이크로 컴퓨터(2)는 원호의 크기 및 직선의 길이를 점(좌표값)으로서 지시하는 것에 의하여 선(線)으로서 연산하는 것으로, 제2(a)도에 있어서 반지름이 동일하다고 볼 수 있는 원호(A)의 점(a)(시작되는 점), 점(b)(중간점), 점(c)(마지막도착점)의 3점의 x, y 좌표값을 동일하게(c) 내지(g)의 각 점에 대하여 곡선지시후 데이터를 입력하는 것에 의하여 원호((A), (B), (C)가 곡선으로서 연산되고, 직선은 점(g), 점(h)의 2점의 x, y 좌표값을 직선지시 후 데이터를 입력하는 것에 의하여 직선(D)으로서 연산하며, 이것을 점(h) 내지 점(a)까지 반복하여서 데이터를 입력하는 것에 의하여 칼날부분(M1)(제5도 참조)의 전후. 좌우방향의 절삭이동궤적이 마이크로컴퓨터(2)에 부설한 그래픽 디스플레이 장치(2')로 표시되어 나온다.The microcomputer 2 calculates the size of a circular arc and the length of a straight line as a point (coordinate value), and computes it as a line, and in FIG. 2 (a), the circular arc which can be regarded as having the same radius ( The same x and y coordinate values of three points (a) (starting point), point (b) (middle point) and point (c) (last arrival point) of A) are the same as (c) to (g). The circular arcs ((A), (B), and (C) are calculated as curves by inputting data after curve instruction for each point, and the straight lines are x, y of two points of point (g) and point (h). The coordinate value is calculated as a straight line D by inputting data after directing the straight line, and the blade portion M 1 is repeated by inputting data by repeating this from the points h to points a (see Fig. 5). The cutting movement trajectory in the left and right directions is displayed by the graphic display device 2 'attached to the microcomputer 2.

다음에 제2(b)도에 의하여 칼날부분(M1)이 전기한 이동(X)방향에 따라서 상하방향으로 절삭이동하는 궤적의 x, z 좌표값을 전기한 조작과 동일하게 행하여서 그래픽 디스플레이장치(2')로 표시되어 나온다.Next, as shown in FIG. 2 (b), the graphic display is carried out in the same manner as the operation in which the x and z coordinate values of the trajectory which is cut and moved in the vertical direction along the moving (X) direction that the blade portion M 1 has been posted. It is indicated by the device 2 '.

이것에 의하여 칼날부분( M1)의 전후. 좌우. 상하방향의 절삭이동궤적이 수치로서 얻어진다.This is before and after the blade portion (M 1 ). Right and left. The cutting movement trajectory in the vertical direction is obtained as a numerical value.

이 칼날부분(M1)의 절삭이동궤적은 마이크로컴퓨터(2)에 어느 일정의 과대반지름을 보유하는 곡선으로서 연산파악한 경우는 직선으로서 표시되어나오는 지시를 부여하는 것에 의하여 궤적선상의 임의의 점의 좌표값을 모두 곡선으로 3점씩 데이터를 입력하는 것에 의해서도 가능하다.The cutting movement trajectory of the blade portion M 1 is a curve having a certain excessive radius on the microcomputer 2, and when a calculation is found, an instruction is displayed as a straight line. It is also possible to input data of 3 points by a curve in all coordinate values.

다음에 칼날부분(M1)은 절삭할 때에 직선으로 이동하기 때문에 그 이동량(j)을마 이크로컴퓨터(2)에 입력한다.Next, since the blade portion M 1 moves in a straight line when cutting, the moving amount j is inputted into the microcomputer 2.

이것은 칼날부분의 최소이동량으로서 직선궤적의 이동인 경우는 좋으나, 곡선적 궤적의 이동인 경우는 절삭가공면이 다각형으로 되기때문에 이 이동량은 원호지름에 의하여 한층더 적은 이동량으로 연산수정한다(제4도참조).This is the minimum amount of movement of the blade, which is good for linear trajectory movement. However, in the case of curved trajectory movement, the cutting surface becomes a polygon, so this movement amount is calculated and corrected by a smaller movement amount by the circular arc diameter (fourth). See also).

위에서 설명한 각 데이터는 피가공물(W)을 절삭하는 칼날부분(M1)의 소위 절삭점의 궤적데이터이며, 가공기(5)에 배설한 각 서어보모우터에 의하여 이동하는 점(p)(이하 기계점이라 칭한다)은 제2(a)도에 있어서 칼날부분(M1)의 x, y 방향의 이동궤적중의 점(k)에 있어서 기계점(p)은 그 점(k)의바로위에 위치하고, 제2(b)도에 있어서의 동일한 x 좌표위치의 궤적중의 점(k')에 있어서의 기계점(p)은 피가공물에 대하여 수직위에 위치하고 있다.Each data described above is the locus data of the so-called cutting point of the blade portion M 1 for cutting the workpiece W, and the point p (hereinafter referred to as a machine) moved by each servomotor disposed on the machine 5. In Fig. 2 (a), the machine point p is located directly above the point k at the point k in the movement trajectories of the blade portion M 1 in the x and y directions. The machine point p at the point k 'in the locus of the same x coordinate position in FIG. 2 (b) is located perpendicular to the workpiece.

이것에 의하면 곡선을 절삭하는 경우(제2(b)도)는 칼날부분이 (M1)피 가공물에 대하여 수직으로 접하면서 절삭하기 때문에 소망하는 곡면을 얻을수가 없었다.According to this configuration if a cutting curve (Claim 2 (b) Fig.) Was not obtained the desired surface, because cutting with the blade in contact with the vertical part (M 1) with respect to the processing member.

즉 곡면절삭과정에 있어서 항상 칼날부분(M1)이 가공곡면에 대하여 직각, 바꾸어 말하면 가공곡면의 법선(法線)위에 전기한 기계점(p)이 위치하는 것에 의하여 소망하는 곡면을 얻을수가 있다.In other words, in the surface cutting process, the blade part M 1 is always perpendicular to the machined surface, in other words, the desired machined surface can be obtained by placing the machine point p on the normal of the machined surface. .

따라서 위에서 설명한 데이터에 절삭점에서 기계점(p), 즉 가공기(5)에 배설한 서오보모우터(7)에 의하여 헤드(6)가 선회하는 선회반지름(m)을 마이크로컴퓨터(2)에 데이터를 입력시키는 것에 의하여(제5도)곡선궤적(n)의 점(k)에 있어서의 선회각도(α) 및 기계점(p')의 x, z 좌표를 연산한다.Therefore, in the above-described data, the turning point m of the turning of the head 6 by the servo motor 7 disposed at the cutting machine 5 at the cutting point, that is, on the machine 5 is transmitted to the microcomputer 2. By inputting (Fig. 5), the turning angle α at the point k of the curve trajectory n and the x and z coordinates of the machine point p 'are calculated.

이것들에 의하여 가공기(5)에 있어서의 기계점(p')의 x, y, z 및 칼날부분의 경사각도의 수치, 즉 기계점의 궤적을 얻는 것으로서, 칼날부분(M2), (M3)…의 각각 그것에 대해서의 그 수치를 연산한 후 NC 테이프작성기에 의하여 NC 테이프로하고, NC장치에 설치해서 가공기를 작동하는 것에 의하여 처음부분에 기재한 곡면을 보유하는 제품을 얻을수가 있다.As the value of the tilt angle of the x, y, z and the blade portion of the instrument point (p ') of the processing machine (5) also by them, that is, to obtain the trajectory of the instrument point, the blade part (M 2), (M 3 )… After calculating the numerical value for each of them, the NC tape maker makes NC tape, and installs the NC machine to operate the processing machine to obtain the product having the curved surface described at the beginning.

또한 좌표판독기, NC 테이프작성기등의 기기(機器)는 이들의 능력을 갖추어 놓은 다른 기기로 바꾸어 놓을 수 있는 것은 말할것까지도 없다.It goes without saying that machines such as coordinate readers and NC tape writers can be replaced with other machines equipped with these capabilities.

또한 제2(b)도에 있어서, 칼날부분(M1)의 곡면궤적을 그래픽디스플레이장치(2)에 연산하여 표시되어 나올때에 반지름을 동일하게하는 원호를 토대로하여서 연산하였으므로, 제5도에 표시하는 그 중심점의 x, z 좌표는 이미판명하고 있으며, 따라서 점(k)까지의 거리(ok)와, 선회반지름(m)의 데이터입력에 의하여 그 연장선위(법선)의 점(p')(선회반지름(m'))까지의 거리는 판명하고, 점(k)의 x, z 좌표와 점(o)의 x, z 좌표의 차에 의하여 ko, ok가 판명되는 것에 의하여 직각 3각형을 형성하며, 따라서 각도(α)(α')는 대향각이기 때문에 점(p')의 x, z 좌표 및 그 각도, 즉 가공곡면에 대한 칼날부분(M1)의 각도가 연산된다.In addition, in FIG. 2 (b), when the curved surface trace of the blade portion M 1 is calculated and displayed on the graphic display device 2, it is calculated based on an arc having the same radius. The x and z coordinates of the center point are already known. Therefore, the point p 'of the extension line (normal) is determined by the data input of the distance ok to the point k and the turning radius m. The distance to the turning radius (m ') is known, and a right triangle is formed by determining ko and ok by the difference between the x and z coordinates of the point k and the x and z coordinates of the point o. Therefore, the angle α (α ') is the opposite angle, so the x and z coordinates of the point p' and its angle, ie the angle of the blade portion M 1 with respect to the machining surface, are calculated.

또한 도면표시 실시예는 복수의 칼날부분을 보유하는 헤드가 선회하는 형식의 목공용 루우터기계에 실시하였으나, 칼날부분을 병렬시킨것에도 적용할 수 있다.In addition, although the drawing display embodiment was implemented in the woodworking router machine of the type which the head which hold | maintains a plurality of blade parts turns, it is applicable also to a parallel blade part.

본 발명에 의하면 복합곡면의 절삭이 자동적으로 행하여져서 참신한 표현의 제품이 용이하게 얻어진다.According to the present invention, the composite curved surface is automatically cut, whereby a product of novel expression is easily obtained.
