Methods and apparatus for machining components

A milling machine comprising:

• an assembly for machining a seal wire groove into a gas turbine rotor blade that includes a dovetail, said assembly comprising:
• a base portion;
• a body portion coupled to said base portion;
• a first set of retainers removably coupled to said body portion, said first set of retainers comprising an upper portion having a profile that substantially mirrors a portion of a first dovetail, and a lower portion having a profile that substantially mirrors an opposite side of the first dovetail, wherein said first set of retainers slidably couple to said body portion, such that said first set of retainers can be replaced by a second set of retainers that are configured to retain a second dovetail that is different from the first dovetail;
• a locking mechanism comprising a first end, a second end opposite said first end, a central portion that couples said first end to said second end, and a handle coupled to said second end, said locking mechanism configured to secure said lower portion within said body portion;
• and
• a grinding wheel configured to machine at least one seal wire groove into said dovetail.
