、Ｙｄ）が定盤[Industrial Application Field] The present invention relates to a numerical control data processing method for correcting numerical control data when cutting, printing, etc. on a steel plate using a cutting machine, a printing machine, etc. [Prior art] Generally, as shown in Fig. 3, a rectangular transparent section is cut out from a steel plate (2) placed on a surface plate (1) using a laser cutting machine or the like. When making a transparent hole (3), consider that the transparent hole (3) is a rectangle ABCD, and as shown in Figure 4, align the point A of the rectangle with the origin 0 of the XY plane, and In the state where the X-axis coordinates are aligned, each point mA on the XY plane mK and G of each point A and D
(0, O), B(X+, 0). Derive C(X irises, Y+) l D(o + Y+),
The coordinates of the derived points A and D are input in advance to the numerical control means (hereinafter referred to as N0 means) as numerical control data (hereinafter referred to as NC data) for cutting the steel plate (1). Then, the coordinates of the points A and D, which are the NO data inputted to the N0 means, are converted into coordinates with the installation point of the cutting machine as the origin based on the relative position of the cutting machine with respect to the surface plate (1). , the cutting machine is moved along the line connecting the actual points A and D on the steel plate (2) represented by the converted coordinates, and the cutting machine is moved from the steel plate (2) to the point shown in FIG. The area surrounded by the dashed line is cut out to form a rectangular hole (3)
is installed transparently. [Problem to be solved by the invention] However, the No. data entered in advance is the data when the steel plate (2) is placed at the normal position parallel to the surface plate 11). If the cutting machine is placed in the position of
) will be automatically installed transparently, but the steel plate (2) is not parallel to the surface plate [1] and deviates from its normal position, causing the surface plate (1)
), if the cutting machine is moved according to the No. data manually entered in advance, the steel plate (2) will be cut through by the angle of deviation of the steel plate (2) from the surface plate (1). There is a problem in that the position of the provided through hole (3) deviates from the expected position, and similarly when printing with a printing machine, the actual printed position of the character deviates from the expected position. There's a problem. Therefore, after placing the steel plate (2) on the surface plate (1), the steel plate (2) is manually shifted using a crowbar or the like to make the steel plate (2) parallel to the surface plate (1). However, each time the steel plate (21) is shifted, it is necessary to measure whether the steel plate (2) is parallel to the surface plate 11 using a convex or tape measure, which is very time-consuming and reduces work efficiency. , Moreover, the alignment accuracy is poor, the cutting accuracy is poor,
This has the disadvantage of causing a decrease in printing accuracy, etc. In addition, after placing the steel plate (2) on the surface plate (1), it is
It is also considered that an automatic positioning device for the edge end position called ``Control'' is used to automatically position the steel plate (2) so that it is parallel to the surface plate 11).
Since the alignment accuracy of the EPC described above is not so high as about ±]Osm, the above-mentioned manual alignment is eventually required, and there is a problem that it is impossible to improve work efficiency, cutting accuracy, and printing accuracy. [Means for Solving the Problems] The present invention has been made with the above-mentioned points in mind, and includes a numerical control means that cuts a steel plate in a state where it has been placed in advance on a regular position on a surface plate. , multiple cutting by printing machine, etc. When numerical control data for printing etc. is input and the steel plate placed on the surface plate deviates from the normal position, the rotation angle detection means detects the deviation of the steel plate from the normal position. This numerical control data processing method is characterized in that a rotation angle is detected, and a processing means corrects the numerical control data input to the numerical control means by the 1d rotation/color. [Operation] Therefore, in this invention, when the steel plate placed on the surface plate is not parallel to the surface plate but is deviated from the normal position,
The deviation rotation angle of the steel plate from the normal position is detected by the rotation angle detection means, and the numerical control data for cutting, printing, etc. of the steel plate placed at the normal position is inputted in advance to the numerical control means by the processing means. is corrected by the rotation angle,
The cutting machine, printing machine, etc. are controlled by the numerical control means according to the new numerical control data that has been corrected. [Embodiment] Next, FIG. 1 and FIG. 2, which show one embodiment of the present invention, will be described. Now, as shown in Figure 1, a steel plate (21 is a surface plate + 1) K
The steel plate (3) is inserted into the rectangular through hole (3) similar to that shown in Fig.
2), the rotation angle detection means detects the rotation angle of the steel plate (2).
The distances dz and dz from the left side surface of the surface plate (1) at a point P+ at a predetermined distance l from the rear end of the left side surface of the steel plate (2) and at a point P2 at a predetermined distance l from the front end of the steel plate (1) are respectively measured.
1 and the surface plate jtt is calculated by the detection means according to the following equation. 0w 1dt-d21 /D (rad) or θ-tu-' ldt -d21 / D (') where D is the point P+, the foot of the perpendicular line hanging from P2 to the left side of the surface plate (1), /, P 21.Next, a processing means (not shown) converts the rectangle ABCD shown in FIG. 4 on the XY plane into the rotation angle θ.
The coordinates ~D' are derived for each point of the rectangle A'B'σd rotated by The coordinates A' (0, 0), B' (
Xb, Yb), σ(Xc, Yc), D'(Xd
, Yd) is the surface plate

は非常に顕著である。[1] Based on the relative position of the cutting machine to [1], the coordinates are converted to the origin with the installation point of the cutting machine as the origin. By the NO means, the cutting machine is moved along the line connecting the actual points on the steel plate (2) represented by the converted coordinates, and the steel plate (2) is deviated from the normal position by the rotation angle θ. Even if the trap is placed on the surface plate (1), the first
The part surrounded by the dashed line in the figure is cut out, and the steel plate (2
) is in the normal position, and a through hole (3) of the same shape is provided in the same position. At this time, when the rotation angle θ detected by the rotation angle detection means is 30° (rad), the lengths L+ of the sides AB and Be of the rectangle ABCD shown in FIG. L2 for each L+ = 100 countries IL2 = 70 (to)

The coordinates of D are corrected by the rotation angle θ, and the coordinates of each point A' to d obtained through the correction process are used as new NC data. It goes without saying that the above-mentioned NC data correction process is performed in the same way when printing by a printing machine. [Effects of the Invention] As described above, according to the numerical control data processing method of the present invention, when the steel plate (2) is placed on the surface plate (1) with a deviation from the normal position, the steel plate (2) ) can be cut at the same position as when the steel plate (2) is at the normal position, and predetermined characters can be printed at the same position, without aligning the steel plate (2) to the normal position. It is possible to improve work efficiency, and it is also possible to significantly improve cutting accuracy and printing accuracy compared to the conventional method, and the effects are very remarkable.
