Abstract: The invention relates to an apparatus 100 for machining a workpiece with a laser beam 101. The apparatus 100 comprises a machining unit 102 configured to provide a pressurized fluid jet 103 and to couple the laser beam 101 into the fluid jet 103. It further comprises a motion unit 104 configured to rotate the machining unit 102 around an x-axis and/or y-axis, a determining unit 105 configured to determine a first angle between the fluid jet 103 and the y-axis and/or a second angle between the fluid jet 103 and the x-axis, and a processing unit 106 configured to control the motion unit 104 to rotate the machining unit 102 around the x-axis based on the first angle and/or around the y-axis based on the second angle.
