<p>A method of forming a slot (4) in an disc (3) for use in a gas turbine. The method includes providing a rough formed slot (4) with a V configuration and then milling the slot (4) using a conical milling tool (6) or an angled cylindrical tool to provide undulations in the wall of the slot (4). The milling tool (6) traverses through the slot (4) following a trochoidal path.</p> |
