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.

Machine tool health monitoring method

A method for determining locations of supporting points for a machine tool is proposed. Multiple test coordinate sets in relation to the machine tool are used in cooperation with corresponding deformation index values for multiple components of the machine tool to obtain a deformation index equation that relates to assessed deformation of the components in response to different coordinates for the supporting points. The deformation index equation is used to acquire an optimal coordinate set for the supporting points.
