The invention relates to a method for machining a locking groove (9) into a groove flank (5, 6) of a panel comprising an upper and a lower side, whereby the locking groove is provided in the part of the joint groove (4) surrounded by the groove flanks, whereby the locking groove is machined by means of a rotating milling tool (12), comprising a drive (14), a milling head (13), a transmission device (11) for the rotational movement and a mounting for the milling head. The milling has a free radius (r) at least on the mounting side due to the mounting and, during the machining of the locking groove, the milling head (13) has at least a significant proportion of the free radius (r) thereof, in particular, the entirety thereof located in the part of the joint groove surrounded by groove flanks.
