A process to produce a workpiece surface or a groove inner surface on a rod-shaped, especially cylindrical workpiece. From the workpiece, a rotary tool is supposed to be produced. The material removal is done using laser beam pulses, which are directed through a deflection device onto points of incidence within a pulse area with a specified outside contour on the workpiece. Multiple machine axis drives position the workpiece and the deflection device relative to one another so that the pulse area is oriented essentially at right angles to the emission direction of the laser beam pulses and at right angles to the section of the tool surface that has already been produced and that borders the pulse area. While the material is being removed, the at least one machine axis drive moves the pulse area relative to the workpiece along a specified path of motion while maintaining the orientation.
