Methods and apparatus for forming an aperture (102) in a composite component (100) are provided. For example, a method (200) for forming an aperture (102) in a ceramic matrix composite (CMC) component (100) comprises, based on a final dimension of the aperture (102), selecting a tool (106) having a tool (106) size and a cutting surface (108); selecting an angle at which to cut the component (100) with the tool (106); cutting a back surface (110) of the component (100) with the tool (106), the cutting surface (108) positioned at the angle; repositioning the tool (106) relative to the component (100); and cutting the aperture (102) through to its final dimension. The tool (106) may be a core drill (106) with a diameter within a range of 60% to 90% of the aperture (102) final dimension. The angle may be within a range of 10° to 60° with respect to the back surface (110). The aperture (102) may be cut through to its final dimension from a front surface (112) of the component (100).
