Abstract

A machine tool health monitoring method which is to use a predetermined plurality of vibration sensors on a plurality of components of a machine tool and to drive motors of the machine tool to excite the machine tool using an electronic device while the health status of the machine tool is good, and then to perform a diagnostic process to obtain a characteristic cluster consisting of a plurality of modals, and then to define the characteristic cluster as a sample health characteristic cluster. The diagnostic process includes the procedures of vibration transmissibility obtaining, singular value decomposition, curve fitting and modal establishing. In addition, excite the machine tool and proceed the diagnosis process to obtain a current health characteristic cluster. Finally, the current health characteristic cluster is compared with the sample health characteristic cluster to judge whether the machine tool is healthy or not.

Abstract

An electricity supply tool holder for a machining center is provided, and has: a holder body, a stationary coil portion, a rotating coil portion, a lateral fixing portion, and an electrical machinery. The stationary coil portion is provided with a primary coil therein; the rotating coil portion is correspondingly provided with a secondary coil therein; and the lateral fixing portion is fixed on a side of the stationary coil portion used for removably combining with a machining center. When the tool holder is rotated, an external electric power/signal can be transmitted through the lateral fixing portion to the primary coil, then inducing the secondary coil, then the electric power/signal is transmitted to the electrical machinery. Additionally, the lateral fixing portion can be switched into a locked position to temporarily limit rotation, so that it can be used in a machining center of an Automatic Tool Changing (ATC) system.

Abstract

A machine tool of high-frequency vibration is provided. A main shaft structure of the machine tool comprises a rotating shaft, the end of which is provided with a tool holder chuck for fixing a tool holder; the upper portion of which is provided with a rotating coil portion; the main shaft structure is correspondingly provided with a stationary coil portion; and the tool holder is provided with a high-frequency vibration module. By non-contact coils, an external electric power/signal can be transmitted into the high-frequency vibration module to avoid a wear phenomenon in a contact-rotating electrode. Because the inductive coil is arranged outside of the tool holder, the manufacturing cost of the tool holder is reduced, and the convenience of changing the tool holder is increased. Moreover, the machining stability and efficiency of the tool holder are improved by a control method of sensing/feedback signals with wireless transmission.
