METHOD OF MILLING TURBINE VANE PROFILES ALONG THEIR MAIN AXIS

摘要

The invention relates to a process for milling a turbine-blade profile which extends along a main axis from a workpiece. The turbine blade has a convex suction side and a concave pressure side. The suction side is milled with a milling cutter which rotates about an associated axis of rotation and which has an circular and flat endface defined by a rotating configuration with at least one cutting edge. The milling cutter and the workpiece are moved relative to one another approximately perpendicularly to the main axis. The cutting edge of the milling cutter is located in the endface, and the endface is oriented tangentially to the suction side surface to be milled. The pressure side is milled by with a rotating milling cutter whose rotary axis intersects a plane perpendicular to the main axis at an acute angle.
