Analysis in Behavior of Machining-Center Spindle

摘要

Machining-center spindle is composed of double shafts for having Automatic Tool Changer. As the spindle speed dose come to the high-speed domain, the unstable phenomenon is observed. But the behavior of the inserted shaft can not be observed directly. Then, computer simulation in the vibrating behaviors of the internal shaft is carried out, and the suppression of the above behavior is investigated.
