A method for the chip-producing machining of a gear wheel workpiece in a machine uses a cutting tool having at least two geometrically defined cutting edges, which produce material in chip form on the gear wheel workpiece during chip-producing machining. The chip-producing machining is defined by method parameters. The method includes computer-assisted analysis of the production of chips on the multiple cutting edges of the cutting tool and computer-assisted ascertainment of relative forces which will occur on the multiple cutting edges of the cutting tool during the production of chips. The method further includes optimizing the chip-producing machining to prevent the relative forces from exceeding a predetermined limiting value or reaching a limiting range. The optimization step includes providing adapted method parameters by modifying at least one of the method parameters. Chip-producing machining of the gear wheel workpiece is performed using the adapted method parameter(s).
