Abstract

PURPOSE:To make an operator recognize clearly the corresponding relation between the program code shown at a code display part and the operating locus of a machine tool plotted at a plotting part. CONSTITUTION:It is decided whether the operating locus of a machine tool set based on an input program code can be plotted at a plotting part or not (S3). If so, the program code is shown in a white color at a code display part (S4) and also the operating locus of the machine tool set based on the displayed program code is drawn at the drawing part (S5). It not, the program code is shown in red at the code display part (S6).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program code input for numerically controlling the operation of a machine tool and a display device for displaying the operation trajectory of the machine tool.

[0002]

2. Description of the Related Art Conventionally, in a system in which a program code input from a personal computer is transferred to a machine tool and the operation of the machine tool is numerically controlled, the input program code and the operation trajectory of the machine tool based on the program code are displayed. There is a display device. The display device is provided with a code display section and a drawing section. The input program code is displayed on the code display section, and the operation trajectory of the machine tool based on the program code is displayed on the coordinate axes of the drawing section. It is drawn as a line segment.

[0003]

In the above-mentioned conventional display device, the operator can visually recognize the program code and the movement trajectory of the machine tool. However, with the program code displayed in the code display section,
The correspondence with the movement trajectory of the machine tool drawn in the drawing section is not clear, and it is determined whether the movement trajectory of the machine tool is actually drawn in the drawing section based on the program code displayed in the code display section. , It is difficult to make the operator clearly recognize. Therefore, when an impractical program code is input due to an operator's input error and the operation trajectory of the machine tool cannot be displayed on the drawing unit, the operator is made to recognize the existence of such a program code. It may not be possible.

The present invention provides a display device which allows an operator to clearly recognize the correspondence between the program code displayed on the code display section and the motion trajectory of the machine tool drawn on the drawing section. It is an object.

[0005]

A display device according to the present invention includes a code display portion capable of displaying a program code input for numerically controlling the operation of a machine tool, and an operation locus of the machine tool based on the program code. It is determined whether or not the motion trajectory of the machine tool can be drawn on the drawing unit based on the drawing unit and the program code. If it is possible, the program code is coded in a predetermined color. Control that causes the display unit to display the operation locus of the machine tool in the drawing unit and, if it cannot be drawn, displays the program code in the code display unit in a color different from the drawable program code. And means.

[0006]

The present invention will be described below with reference to the illustrated embodiments.
FIG. 1 is a diagram showing a CRT display device of a personal computer which is an embodiment of the display device according to the present invention. In this figure,
The CRT display device 10 is provided with a code display unit 11 and a drawing unit 12, and the code display unit 11 and the drawing unit 12 are controlled by the control device 20, respectively. The control device 20 numerically controls the machine tool 30 via the drive circuit 16 based on the program code input from the keyboard 15.

On the code display portion 11, a program code input from the keyboard 15 and transferred to the machine tool 30 can be displayed in a combination of letters and numbers.
In the drawing unit 12, the operation locus of the machine tool 30 numerically controlled based on the transferred program code, the coordinate axis 1
3 (X axis, Y axis, and Z axis) can be drawn with a line segment 14.

In the control device 20, it is judged whether or not the motion locus of the machine tool 30 based on the inputted program code can be drawn in the drawing section 12, and if the drawing is possible, the program code is changed. For example, while being displayed in white on the code display unit 11, the movement trajectory of the machine tool 30 is drawn by the line segment 14 on the drawing unit 12. When the drawing is not possible, the program code is displayed on the code display unit 11 in, for example, a red color different from the drawingable program code.

FIG. 2 is a flow chart for displaying the program code and the operation trajectory of the machine tool 30 on the code display unit 11 (FIG. 1) and the drawing unit 12 (FIG. 1).

In step S1, the program code is read. In step S2, the content of the read program code is confirmed. In step S3, it is determined whether or not the motion locus of the machine tool 30 can be drawn on the drawing unit 12 based on the program code whose contents have been confirmed in step S2.

When it is determined in step S3 that the drawing is possible, the program code is displayed in white on the code display portion 11 in step S4, and then in step S5.
In step S4, the operation locus of the machine tool 30 based on the program code displayed in step S4 is drawn by the drawing unit 12.
Is drawn with a line segment 14 (FIG. 1).

On the other hand, if it is determined in step S3 that the drawing is not possible, the program code is displayed in red in the step S6, which is different from the white of the drawable program code, in the code display section 11, and the drawing is performed. I don't know.

As described above, according to the above-described embodiment, when the motion locus of the machine tool 30 based on the input program code can be drawn on the drawing unit 12, the program code is white and the code display unit 11 is used. When it is not possible to draw, the program code is displayed in red on the code display section 11, so the program code displayed on the code display section 11 and the machine tool drawn on the drawing section 12 are displayed. It is possible for the operator to clearly recognize the correspondence with the movement locus of 30. As a result, even when an actually impossible program code is input due to an input error, the program code will be
It is possible for the operator to clearly recognize that the movement trajectory of the machine tool 30 is not reflected in the drawing.

[0014]

As described above, according to the present invention, the operator can clearly recognize the correspondence between the program code displayed on the code display section and the motion trajectory of the machine tool drawn on the drawing section. You can
