Abstract

A milling device (74, 96, 134) is provided for machining a slot (45) into an inner surface of a casing (42) for a gas turbine engine (11). The milling device (74, 96, 134) includes a frame assembly (76, 98, 136) including multiple structural guides (88, 132) configured to engage structural features (66) on the inner surface of the casing (42) to maintain an axial position of the milling device (74, 96, 134) relative to a longitudinal axis (36) of the casing (42). The milling device (74, 96, 134) also includes a milling cutter (78, 100, 138) coupled to the frame assembly (76, 98, 136). The milling device (74, 96, 134) is configured to be displaced in a circumferential direction (34) relative to the longitudinal axis (36) to machine the slot (45), via the milling cutter (78, 100, 138), along the inner surface of the casing (42) in the circumferential direction (34).

Description

Background technique [0001] The subject matter disclosed herein relates to gas turbine systems, and more particularly, to systems and methods for machining slots into casings of gas turbine systems. [0002] Gas turbines are used to generate electricity for a variety of applications. Typically, these gas turbines are tested and validated before they are used (eg, in a power station). Effective testing and validation can improve the efficiency and productivity of gas turbines as well as power plants. However, installation of equipment used to perform testing and validation on gas turbine engines can be labor intensive and time consuming. Contents of the invention [0003] Certain embodiments commensurate in scope with originally claimed subject matter are outlined below. These embodiments are not intended to limit the scope of the claimed subject matter, but these embodiments are intended only to provide a brief summary of possible forms of the subject matter. Indeed, the...
