Abstract
This paper presents the results of three measurements of dynamic consistency in machine tool spindles. First the effect of reclamping and of the rotational orientation of a tool in a single spindle (40,000 rpm 40 kW) was evaluated. Then 5 different spindles of the same model (20,000 rpm 75 kW) were compared, first with a flexible tool and then with a stiff tool. It was seen that in all the tests the natural frequencies did not vary greatly, but that in some situations the damping showed significant variability. The effect of this damping variation on stability and cutting performance is evaluated for both conventional and for high speed machining.
