A gearbox having an integral wet brake assembly is provided to replace the prior gearbox assembly of an underground mining machine. The bitstream can include different syntax related to time, frequency and spatial domains. The treatment planning system iteratively determines the twist angle of the archwire at each appliance position along the length of the archwire and incrementally adjusts the orientation and the position of each tooth based on the determined twist angles until the twist angle at each position along the archwire is within a defined tolerance of zero. In this way both the speed of a feed-forward arrangement and the accuracy of a feedback arrangement can be achieved.
