1. A method to produce a ceramic matrix composite part, the method comprising:
providing a ceramic fiber preform, the ceramic fiber preform including a three-dimensional framework of a plurality of ceramic fibers;
prior to melt infiltration, adding a layer of machinable stock to only a target area of the ceramic fiber preform, wherein the target area comprises less than a total surface area of the ceramic matrix composite part;
melt infiltrating the ceramic fiber preform;
forming the ceramic matrix composite part by cooling the melt infiltrated ceramic fiber preform;
machining the part in the target area where the machinable stock is located; and forming a precision feature in the machinable stock disposed on the target area.
