The dynamic stability of a workpiece in a fixture is a critical indicator of machining fixture performance and is affected by a variety of factors. This paper presents a parameter effect analysis of fixturing dynamic stability in machining based on a previously developed stability model. The effects of four major factors - spindle speed, static coefficient of friction, fixture layout, and clamping forces - on the dynamic stability of a fixtured workpiece are investigated and the predominant effects are identified. Further, the effect of imprecision of the static coefficient of friction on the fixturing dynamic stability is examined. A numerical example is presented and insightful interpretations are given.
