The invention relates to a method for producing a groove (10) in a workpiece (12), in which a liquid-abrasive mixture (22) is injected in an injection direction (14) from a nozzle (24) to produce the groove (10) and is sprayed against the workpiece (12) while the nozzle (24) is moved relative to the workpiece (12) in a direction of movement (26), a sliding shoe (28) being provided which with the nozzle (24) into the Movement direction (26) is moved relative to the workpiece (12), thereby diverted on the workpiece (12) and covers at least an already produced portion (T) of the groove (10) during its production.
