Near Net-Shape Five-axis Face Milling of Marine Propellers

다국어 초록 (Multilingual Abstract)

We present an optimal cutter location (CL) data computation for face-milling of large marine propellers composed
of CL point optimization and CL path optimization on a given tool path. The CL point optimization at a single
cutter contact (CC) point is conducted by maximizing the effective radius of the face milling cutter, while the CL
path optimization on a series of CC points is performed by conforming deviation of the tool-swept surface from the
design surface between consecutive CL data to a given machining tolerance. The proposed algorithm was
implemented and applied to the machining of a large marine propeller which proved effective from a quantitative
point of view, and is used on the shop floor in a Korean ship building company.
