Machine tools and methods for machining turbine rotor assemblies are disclosed. Some machine tools include a drill arm that pushes off of a turbine stage that is adjacent to a turbine stage to be machined. Some machine tools include a clamping arm that secures the machine tool to a turbine stage to be machined and an adjacent turbine stage. Some methods include pushing-off of a turbine stage that is adjacent to a turbine stage to be machined. Some methods include securing a machine tool to a turbine stage that is adjacent to a turbine stage to be machined. Some methods include monitoring at least one of a current delivered to a first motor and a voltage applied to the first motor and controlling a second motor in response to the monitoring. Some methods include sequentially machining a turbine stage with cutting tools having increasing lengths and/or diameters.
A method for machining a turbine rotor assembly with a machine tool, wherein the turbine rotor assembly includes a plurality of turbine stages, wherein each turbine stage is defined by a turbine wheel and a plurality of turbine blades extending from the turbine wheel, wherein each turbine blade is coupled to a respective turbine wheel by one or more pins, and wherein the plurality of turbine stages includes a first turbine stage to be machined, a second turbine stage that is adjacent to the first turbine stage, and a third turbine stage that is adjacent to the first turbine stage and opposite the second turbine stage, the method comprising:
