Abstract
A turbine blade machining method and a machining tool, which allow efficient machining of a through-hole running from the surface of a turbine blade to the interior thereof, and a turbine blade. This turbine blade machining method, in which a through-hole is machined in a turbine blade with a protective film formed on a surface of a substrate, has: an insertion step of inserting a machining tool, including a grinding region provided at a tip thereof, into the through-hole with such an orientation that the grinding region faces the surface of the through-hole; and a removal step of grinding the protective film laminated in the through-hole with the grinding region of the machining tool inserted into the through-hole, to remove the protective film laminated in the through-hole.
