A method for finishing a part having excess material includes generating one or more surfaces on a model of the part to be machined, creating a machining tool path drive geometry, using the machine tool path drive geometry and one or more surfaces on the model to be machined to generate machining tool paths on the surfaces; and running tool paths on the part in a fixture. Each stage comprises a peak finder arranged to find at least one peak of the input signal exceeding a threshold level, and to make a list comprising information on a number of the highest peaks or information on each peak; a peak selector adapted to receive the list and to receive, from each preceding stage, a list with information on unreduced peaks and the stage number. The coils have a different sensitivity with respect to a field generated by the sample. The group formatter forms a group of enhanced data having head, body, and tail regions and inserts the expanded data and transmission parameters into the body region. The metal insert aids in the alignment and installation of the seal.
