ENGRAVING DEVICE, COMPUTER PROGRAM FOR ENGRAVING TO BE APPLIED FOR ENGRAVING DEVICE, AND MANUFACTURING METHOD OF PROCESSED MATERIAL ON WHICH DESIRED IMAGE IS FORMED BY AGGREGATION OF POINT-MARK

摘要

PROBLEM TO BE SOLVED: To form a desired image on a workpiece in a short period of time and also to improve quality of an image formed on the workpiece by engraving a line drawing portion in the image such as a straight line and a curved line as a smooth continuous line.;SOLUTION: An engraving device 10 is equipped with a carriage 30 that holds a line marking tool 31 to engrave line marks on a surface of the workpiece WK, and a carriage 40 that holds a point marking tool 41 to engrave point marks on the surface. The line marking tool 31 and the point marking tool 41 are actuated based on the line mark engraving data and the point mark engraving data which are generated by an outside computer unit 60. Based on image data showing the desired image, the outside computer unit 60 generates both the line mark engraving data to engrave the line drawing portions, which are outline portions OL1, OL2, and the point mark engraving data to engrave a picture portion PI, and outputs them to the engraving device 10.;COPYRIGHT: (C)2008,JPO&INPIT
