Abstract
Methods and apparatus for cutting a groove in a structure are disclosed. Large structures such as steam turbines have pumping grooves or similar features which may be machined using the simplified methods and apparatus disclosed. In a preferred embodiment, a milling head affixed to a magnet which may be selectively activated is provided. Additional clamping means are also provided which are affixed to the magnet and engage the structure to further affix and align the apparatus in place. The milling head is positioned at the location of the groove and held fast by the magnet; the additional clamping means ensure the apparatus stays in place while the groove is being cut. The apparatus disclosed may be operated by a single operator using conventional power sources and without the need for extensive set up, fixturing and the like normally associated with milling operations of this nature.
