ABSTRACT:
A machining system includes a support configured to retain an article, such as a rotor disk, having an area, such as a surface of a slot in the disk. A cutting tool, for example, a broach, is movable relative to the support to cut the area. A heating member, such as a laser, is configured to locally heat the area of the article. In one example, the cutting tool includes a body having a cutting edge. The heating member is supported by the body and is configured to provide heat adjacent to the cutting edge. The cutting edge cuts the locally heated area while the area is still heated.
