Electric spark recording |
摘要 |
A graphic recording technique is disclosed for the enlargement of a relief configuration. A micro-stylus is used to scan the configuration laterally while measuring vertical irregularities in the surface; and a recorder stylus is synchronized therewith to record the scan. A series of scans are provided where each successive scan is offset from the previous scan to produce a topographical representation of the relief configuration from the recorder stylus. Vertical movements of the micro-stylus along the surface of the relief configuration are reproduced by the recorder stylus as movements on the ordinate axis in combination with the scan offset thus producing a two dimensional graphical display of a three dimensional relief configuration. Hidden contours of the relief configuration are accurately suppressed by causing the recorder stylus to stop recording at the boundary of a previously written scan area and to begin recording once the previously recorded area has been departed.
