A method for machining at least one workpiece surface to apply a texture pattern to at least one section of the workpiece surface using a laser, based on image data specifying an image of the texture pattern applied to the at least one section of the workpiece surface and model data specifying a three-dimensional geometry of a surface form corresponding to the at least one section of the workpiece surface. Control data and segment data are generated based on the image and model data. The control data specify one or more segment sequences for each track line. Each segment sequence has track segments where the laser guides the texture pattern application to the at least one section of the workpiece surface; wherein the track segments of a segment sequence include one or more laser track segments where the laser travels in the switched-on state at a constant machining setpoint speed.

In a method for machining workpieces within a machining machine a tool is moved relative to a workpiece (1). The tool or the workpiece (1) travels at a predeterminable travel speed in a travel direction which is predetermined by a movement path (3). The movement path (3) is divided into machining portions (4) and acceleration portions (5). Within the machining portions (4), the workpiece is machined between a starting point (6) and an end point (7) of the machining portion (4) at a predeterminable machining travel speed in a machining travel direction. The travel speed is adjusted along the acceleration portion (5), which is defined by the end point (7) of a first machining portion (11) and the starting point (6) of a second machining portion (12), such that the predetermined machining travel speed is reached at the starting point (6) of the machining portion (4).
