Abstract
A blade having a concavely shaped leading edge is cut. The blade has first and second side faces, a tip profile and a root profile. Each profile has a first and second profile side corresponding with the first and second side faces. The cutter is positioned between the first root profile side and the first tip profile side. The tip profile and root profile are followed with two cutter portions of the cutter along the first root and tip profile sides toward the leading edge to cut the first side face. One of the cutter portions is translated around to the second profile side before the other cutter portion is translated to the second profile side, causing the formation of the concave leading edge. The tip and root profile is followed with the cutter, along the second profile side away from the leading edge to cut the second side face.
