Abstract:
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.
