DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a graphic display device and, more particularly, to a graphic display device which displays the contents of a numerical control (NC) machining program as the locus of a tool.
Conventional display devices of this kind are equipped with functions of displaying an NC machining program as well as a tool locus, but these displays are provided independently of each other, and hence do not bear a clear correspondence therebetween. Because of this, finding an error at a certain place along the tool locus being displayed and correcting the corresponding part (block) of the NC machining program is not easy because it is not easy to pick up or determine the associated block from the NC machining program; this is all the more difficult in the case where the tool locus is partly displayed on an enlarged scale.
SUMMARY OF THE INVENTION
An object of the present invention is to move a cursor along the tool locus being displayed on a screen and to display thereon, together with the tool locus, the NC machining program block corresponding to the locus at the position of the cursor, allowing ease in confirming the contents of an NC machining program on which the tool locus is based. An NC machining program is input into graphic form generating means, where it is interpreted and a series of graphic data necessary for displaying a tool locus are prepared. The graphic data thus produced are each stored in graphic data storage means, the contents of which are provided to a display unit for displaying the tool locus on a screen. Further, an NC machining program block for each graphic form is stored in a program storage means in correspondence to the starting point of the graphic form indicated by each graphic data. Upon application of a cursor move command, cursor control means refers to the contents of the graphic data storage means and moves a cursor along the tool locus being displayed. Program display control means detects whether the cursor has passed through the starting point stored in the program storage means and, if so, reads out of the program storage means the NC machining program block stored therein corresponding to the starting point, for display on the screen of the display unit 3.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 is a diagram of the arrangement of the graphic display device of the present invention. In FIG. 1, an NC machining program is input into graphic form generating means 1, where it is interpreted and a series of graphic data necessary for displaying a tool locus are produced. The graphic data thus produced are stored in graphic data storage means 2 and the contents thereof are provided to a display unit 3 for displaying the tool locus on a screen. An NC machining program block for each graphic form is stored in program storage means 4 with respect to the starting point of the graphic form indicated by the graphic data. Upon application of a cursor move command, cursor control means 5, with reference to the contents of the graphic data storage means 2, and moves a cursor along the tool locus being displayed. Program display control means 6 detects whether the cursor has passed through the starting point stored in the program storage means 4 and, if so, reads out of the program storage means 4 the NC machining program block stored therein corresponding to the starting point, for display on the screen of the display unit 3.
In FIG. 2, which illustrates the hardware structure of the present invention, a program memory 20 for storing an
