A method for automatically minimizing an undesirable motion of a workpiece during a machining operation, and a universal adaptive machining chatter control fixture that operates in accordance with the method. The method comprises the steps of mounting the workpiece to an active, supporting structure, and then machining the workpiece. During the step of machining, an undesirable motion of the workpiece is sensed in the supporting structure. Thereafter, a compensating motion is applied to the supporting structure for minimizing the undesirable motion of the workpiece. The chatter control fixture can be attached to various types of machine tool devices, without requiring that the machine tool devices be retrofitted, and operates to minimize undesirable motions of the workpiece independently of the machine tool devices.

[ What is claimed is:] [1.]1. A method of minimizing an undesirable motion of a workpiece during a machining operation, comprising the steps of:mounting the workpiece to a supporting structure;machining the workpiece and, during the step of machining;sensing, in the supporting structure an undesirable motion of the workpiece, said sensing step including a step of detecting an acceleration of the supporting structure and optionally also acoustic vibrations produced as a result of the undesirable motion, and wherein said step of sensing is performed by sensing accelerations of at least one of the workpiece and the supporting structure, along the x, y, and z axes; andgenerating a compensating motion in the supporting structure for minimizing the undesirable motion of the workpiece, wherein the compensating motion is generated based on the detected acceleration and optionally also the acoustic vibrations.
