摘要: In theory, the five-axis numerical control (NC) machining of sculptured surfaces can be classified into facing milling and cylindrical (or side milling). general, first one, using flat-end cutter, is suitable for large surfaces, e.g. blade hydraulic turbine, whose binding relations with drive surface (DS) check (CS) are simple, second has wide applications small middle dimensional DS CS more complex, such as integral turbine wheels. practice, one suffers difficulties than which mostly related to gouge avoidance, interference avoidance tool strength. This paper, on basis theories differential geometry analytical geometry, describes research algorithms toolpath generation cutter. The approach includes (a) single point offset (SPO) algorithm, (b) double (DPO) algorithm cutter location data (CLDATA) calculation milling.
