Abstract: A laser ablation method for engraving a workpiece with a texture by a laser beam emitted by a laser head integrated in a machine tool comprising: a. generating a plurality of machining layers based on the geometry of the workpiece to be machined in succession; b.

Abstract: A method for computing a machining toolpath applied for laser machining process, in which a laser beam is emitted by a laser head installed in a laser machine tool for ablating the material of a part for forming a pattern thereon.

Abstract: The present invention relates to a method for defining a sequence of relative positionings of a laser head 1 in relation to a part for the machining of a texture etched on the two-dimensional or three-dimensional surface 7 of the part modelled by a 3D meshing, comprising: a step 100 of definition of N machining layers intended to be performed in succession, a step 200 of definition, for each machining layer, of patches intended to be each machined from a single position of the laser head 1, comprising closed patches 15, the boundary of which is not affected by the laser ray 2, a step 300 of validation of the closed patches 15, successively from the machining layer 1 to the machining layer N. Open patches whose boundary is affected by the laser ray 2 being defined for any areas which could not be machined from validated closed patches 15. Optionally, the method also comprises a step 400 of merging of the validated closed patches 15 into groups 50 of patches.
