Automated reheat stop valve seat restoration

An automated method for restoring an end surface of a cylindrical component of a turbine engine by cutting a profile into the end surface, comprising:

• installing a base of a cutting device against an inner diameter of a cylindrical component of the turbine engine so that the cutting device is entirely secured and supported by the base on the interior of the cylindrical component;
• aligning the base to the end surface of the cylindrical component;
• positioning a cutting head of the cutting device to a desired position to enable the cutting of the profile by moving the cutting head via a controller a radial and/or an axial distance to the desired location and setting a path extent including an axial distance and a radial distance using the desired location for the cutting head from a graphical user interface;
• activating a motor of the cutting device to rotate the cutting head about a central axis of the cylindrical component to cut the end surface of the cylindrical component;
• creating a profile of the end face by the cutting of the end surface via the motor,
• controlling the motor by a controller of the cutting device, the controller including a processor;
• generating the graphical user interface through a display device allowing a user to visually select and input control parameters for the cutting device;
• receiving inputs from the user through the graphical user interface corresponding to the input control parameters,
• wherein upon activation of the motor, the cutting device is guided along a circumferential direction against the end surface,
• wherein the cutting device is entirely disposed within the interior of the cylindrical component, and
• wherein the controller is configured to control the cutting head via the processor based at least in part on the inputs received through the graphical user interface so that the cutting head is guided by the motor to precisely cut a contoured profile into the end surface described by the path extent utilizing the same cutting head.
