Integrated planning for precision machining of complex surfaces. Part 2: Application to the machining of a turbine blade die

The applications of the proposed cutting-path-adaptive-feedrate strategy, described in part 1 of this paper, to real three-dimensional complex surfaces are examined. Its applications to the aerospace, automobile, and die-mold industries are of particular interest. As an example, the proposed strategy is used in planning the machining of a turbine blade die. This process consists of rough milling (using the stock material), and the subsequent semi-finish and finish milling operations. Computer simulations along with experimental verifications are presented in this paper.
