| 摘要 |
The present invention relates to a laser ablation method for engraving a surface (7) of a two or three dimensional workpiece with a texture (16) by a laser beam (2) of a laser machining head (1). Surface engraving is performed in one or more layers (17.1, 17.2) which are machined sequentially. Each defined layer (17.1, 17.2) to be machined is subdivided into one or more patches (11) intended to be sequentially machined using the laser beam (2). According to the present invention, a borderline (18) of at least one patch (19) is determined to follow a path on the layer (17.1, 17.2, 17.x) which will not be affected by laser beam (2) engraving of the laser machining head (1). |
