Investigation of machining stability in micro milling considering the parameter uncertainty

摘要: Micro milling can fabricate miniaturized components using micro end mill at high rotational speeds. A major obstacle that limits the productivity in machining operations is presence of machine tool chatter. The analysis stability plays an important role characterizing cutting process, estimating life and optimizing process. But majority traditional models used to predict chatter assume parameters remain unchanged. In reality, affecting vary with spindle speed dynamic characteristic system. numerical experimental method present investigate process considering parameter uncertainty. robust model based on analytical developed, edge theorem zero exclusion condition are used. verified experimentally for mic...
