The laser code carving machine body 21 is used for etching the first tracing code in the tracing code data set stored in the cache subunit 22 on an object, and removing the tracing code after the etching is finished. Specifically, the first tracing code D1 in the tracing code data set is etched on the object, and after the etching is completed, the tracing code D1 is removed. At this time, the first tracing code is changed into D2, and when the laser code carving machine body 21 is etched next time, the first tracing code is changed into D2.

Specifically, the laser lithography code machine etches the first tracing code D1 in the tracing code data set on the object, and after the etching is completed, removes the tracing code D1. At this time, the first traceback code is changed into D2, and when the laser lithography code machine is etched next time, the first traceback code is changed into D2. The laser code etching machine finishes etching with the first tracing code every time, removes the first tracing code after the etching is finished, continues etching the next object, and performs the steps repeatedly in the way to realize automatic high-speed code etching.
