Abstract
In a preliminary study on the machining accuracy of a jig boring operation, the structure of a modified universal milling machine was found defective. A project investigating possible design defects for the future refinement of the structure was conducted using a proposed simulated physical model. Two methods, one being computer-analytic and the other time-domain experimental, were introduced to help the design of a simplified spindle-head-column physical structure. The model was constructed graphically in a CAD workstation with the aid of finite element analysis (FEA). The structural dynamics was verified by a time-domain experimental modal analysis (TMA) method. In an automatic modeling procedure, the mathematical analogy of the structure and the related parameters of each dynamic mode were identified in sequence.
