Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plane figure definition circuit in a numerical control device.

When defining a figure, there are the following.

Example 1. Straight line segment (in the case of Figure 1) GotXx'iYylFl* Example 2. Arc line segment (radius specified arc, in case of Figure 2) Ga4
(Ga3) xo
, yo are the coordinates of the starting point, x1 and y1 are the coordinates of the end point, r1 is the radius, i1 and j1 are the coordinates of the center of the arc, and f1 is the feed rate.

In FIGS. 2 and 3, the arrow on the arc indicates Go2 (clockwise rotation).

In FIG. 2, the starting point (xc, yo) and the ending point (xl.

I have drawn two types of arcs connecting yl), which are distinguished by the positive or negative sign of the radius; if it is positive, it is an arc that is less than a semicircle, and if it is negative, it is an arc that is more than a semicircle.

In conventional figure definition circuits, the end point coordinates must be specified because of the above definition, and these data must be determined before input. For this reason, when the figure becomes complicated, the time and labor required to calculate the intersection point to determine the coordinates of the end point increases. Also, X, Y, R.

The disadvantage was that addresses I and J had to be entered for each numerical value setting, which required extra key operations.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional method, and it allows figure definition even if the end point coordinates are not necessarily determined, and also allows data input by displaying the address as a head item. The purpose is to simplify the previous work and the work at the time of data entry.

An embodiment of the present invention will be described below.

In Fig. 4, (1) is an input means, (2) is a display means, and (3) is a display means with six head items: end point coordinates, radius/vector angle, arc center coordinates or vector components, and modifiers. Display control means (4) divides the planar figure into straight line segments and circular arc line segments and sets the known data by sequentially or appropriately using the addresses displayed on the display means. (5) is a means of calculating using set data for unknown data for which no numerical value has been given;
(6) is a central processing means, and (7) is a memory.

In the above configuration, the address displayed on the display is the same as the head item for straight line segments and circular arc line segments.

Of these, Figures 1 and 6 to 8 are related to straight line segments, and Figure 1 (A-1) is the same as the conventional figure definition method, and the end point coordinates are given. Figures 6 to 9 show the figure definition methods that can be added with this invention. Figures 5 (A-2) and 9 (A-3) are given one end point coordinate and a vector angle; Figure 8 (A-4)
, FIG. 9 (A-5) shows one end point coordinate and a vector component given.

Also, Figures 2, 3, and 10 to 13 relate to circular arc segments, where Figure 2 (A-6) is a conventional radius specified circular arc, and Figure 3 (A-7) is a conventional circular arc. 10 to 13 are figure definition methods that can be added with this invention. Figure 10 (A-8)

In all of the figure definition methods that can be added, the end point coordinates are not given, and the modifier P is used.

Figures 14 to 16 relate to straight line segments, and the first

Y212, j2 In this invention, to define a figure, the figure is divided into straight line segments and circular arc line segments, and for the specification of the straight line segments and circular arc line segments, all end point coordinates are specified instead of the conventional method. For straight line segments, end point coordinates (X, Y), vector angle θ, vector components (I, J), modifier P; for circular arc components, end point coordinates (X, Y), radius R, arc center coordinates. Six addresses (I, J), modifier P can be used to set known data sequentially or as appropriate, and unknown data for which no numerical value has been given is calculated using known data. It allows you to define shapes.

Therefore, when setting data, refer to the figure definition pattern in Figure 5 and set known data or data that is easy to find in sequence or as appropriate according to the address, and the end point coordinates may not necessarily be found. It is now possible to define shapes without having to do so.

In addition, in the above embodiment, the address displayed on the display is the same as the head item for straight line segments and circular arc segments, but it is divided into straight line segments and circular arc segments as follows. May be displayed.

For a straight line segment: XYθI, rP (CNR10NG) For a circular segment: XYRIJP (CNR10NO) As described above, according to the present invention, when defining a planar figure, it is no longer necessary to specify the end point coordinates as in the past. In comparison, even if the end point coordinates are not necessarily determined, it is possible to define the end point by calculating the end point coordinates using other data. Since it can be displayed in advance, input for defining a figure can be made easy.

Detailed Description of the Invention The present invention relates to a plane figure definition circuit in a numerical control device. When defining a figure, there are the following. Example 1.

In Figure 3 of the 11EIH, xo and yo are the coordinates of the starting point, and Xl and 7N are the coordinates of the ending point. rl is the radius, il and jl are the coordinates of the center of the arc, and fl is the feed rate. In FIGS. 2 and 3, the arrow on the arc indicates the case of GO2 (clockwise rotation). In Figure 2, two types of arcs connecting the starting point (xo, yo) and the ending point (xl, yt) are drawn, and these are distinguished by the sign of the radius (positive or dog), and if it is positive, it is a semicircle. In the case of the following circular arcs, in the case of a dog, the circular arc is more than a semicircle.2 In conventional figure definition circuits, the end point coordinates must be specified due to the above definition, and these data must be determined before input. It was necessary for me to be there. For this reason, when the figure becomes complicated, the time and labor required to calculate the intersection point to determine the coordinates of the end point increases. Also, X, Y, R. This invention was made in order to eliminate the above-mentioned drawbacks of the conventional device, which had the disadvantage of having to input addresses 1 and J for each numerical value setting, which required extra key operations. The purpose is to simplify the work before data input and the work at the time of data input by making it possible to define a figure even if the end point coordinates are not necessarily determined and by displaying the address as a head item. Hereinafter, one embodiment of the present invention will be explained. In FIG. 4, (1) is an input means, (2) is a display means, and (3) is a head item on this display means, the radius or vector of an arc of end point coordinates.

The shapes are the same as those in FIGS. 1, 2, and 3, respectively. 1 to 3 and FIGS. 6 to 13 belong to the above-mentioned A type (those whose figures can be defined using input data). Of these, Figure 1. Figure 6H Figure 9 relates to straight line segments, and Figure 1 (A

It is a given. In addition, Fig. 2, Fig. 3, Fig. 10H, Fig. 13 are related to circular arc segments, Fig. 2 (A-6) is a conventional radius specified circular arc, and Fig. 3 (A-7) is a conventional circular arc. 10 to 13 are figure definition methods that can be added with this invention. , Figure 10 (A-8

Figures 14 to 18 show the above-mentioned B type (the input data alone is insufficient, but it is possible to define the figure using the data of the 9th order line segment). This is a figure definition method that can be added with this invention, in which the end point coordinates are not given and the modifier P is used. ,

Figure 19H and Figure 24 belong to the above-mentioned C type (the figure definition (2) has extra data, but that data is used for the figures before and after it). A modifier P is used in the figure definition method that can be added with this invention. Figures 19 and 20 are related to straight line segments.

G code xyR/θ Got is θ Ga4X2Y2r where X, Y are the end point station marks, and R/θ is the radius (in the case of a circular arc segment) or the vector angle (in the case of a straight line segment).

I, J), and the modifier P, which allow known data to be set by using each of the six addresses sequentially or as appropriate, and unknown data for which no numerical value has been given can be calculated using known data. It is possible to define shapes. For this reason, when setting data, refer to the figure definition pattern in Figure 5 and set known data or desired data sequentially or appropriately according to the address. It is now possible to define a figure even if the coordinates have not been determined. In the above example, the address displayed on the display indicates the head item that is common to straight line segments and circular arc line segments. However, straight line segments and circular arc line segments may be displayed separately as shown below. According to the present invention, when defining a planar figure, the end point coordinates can be calculated using other data even if the end point coordinates are not necessarily determined, compared to the conventional method that always specifies the end point coordinates. In addition, unlike conventional methods where addresses were specified together with numerical data, the address can be displayed in advance, making it easier to input data to define nine shapes. 4.
