Abstract

A marking apparatus with a CAD device which is highly productive due to the procedure of entering an image of a workpiece 1 as a marking diagram into the CAD device 40 and constructing a work program synthesizing the marking symbols/drawings onto the marking diagram. The position of the workpiece 1 can be adjusted by monitoring the screen because an image of the workpiece 1 is displayed on the display device 4N of the CAD device 40 as a marking diagram. Additionally, marking symbols/drawings of an arbitrary scale can be synthesized in cooperation with the marking diagram of the workpiece, since the scaling ratio of the image of the workpiece 1 is displayed on the display device 4N.

Claims

1. A marking apparatus with a computer-aided design device for processing markings onto a workpiece, comprising:

imaging means for taking an image of a workpiece to be marked with markings to be engraved thereon;

image display means for displaying said image of said workpiece, on a display device, taken by said imaging means along with said markings to be engraved onto said workpiece, for determining a necessity of adjusting a position of said workpiece;

program construction means for constructing a work program based on the displayed workpiece and markings;

engraving means for engraving markings onto said workpiece; and

control means for moving said engraving means in X and Y directions based on said work program.

2. A marking apparatus with a computer-aided design device for processing markings onto a workpiece, comprising:

imaging means for taking an image of a workpiece to be marked with markings to be engraved thereon;

an image entering section for converting said image taken by said imaging means into a bit-map file and outputting the converted file;

image display means for displaying said bit-map file, on a display device, along with markings to be engraved onto said workpiece, for determining a necessity of adjusting a position of said workpiece;

program construction means for constructing a first work program based on the displayed bit-map file and markings;

engraving means for engraving said markings onto said workpiece by pressing and moving a rapidly vibrating stylus over said workpiece; and

control means for constructing a second work program based on said first work program, then moving said engraving means in X and Y directions based on said second work program.

3. A marking apparatus with a computer-aided design device according to claim 2, wherein

said program construction means is capable of enlarging and contracting said marking symbol and drawing displayed on said display means based on inputted display scaling ratios.
