Among a few items with world wide competitiveness are the semiconductor and the LCD. Grinding/polishing is the most significant process in manufacturing semiconductor wafers and LCD panels, the most critical quality of which is the precision rate of the machined surfaces. It is well known that the control of the vibrations is the major factor in maintaining superb machined surfaces. In this paper the dynamic properties of a grinding machine have been investigated through the frequency analysis test and the computer simulation to deduce ideas of design modifications for improved stability. The alterations have been applied to the simulation model, which is supposed to have identical dynamic property with the original structure, to identify the effects and to finally achieve the satisfactory level of stability. The result shows that the machine can have much improved stability with relatively simple design changes, and also can improve the surface quality of the products.

The manufacturing process of the semiconductor is guided by the controller, which is supposed to sense the unexpected shocks and/or vibrations to shutdown the hard disk and the whole system in order to prevent the malfunction. This feature of controller would shutdown the system due to the instability of the controller itself as well as the instability of the manufacturing system. And consequently will cause significant losses. In this study the structure of a controller has been investigated to find ways to suppress the vibrations from the structure. The frequency response test and the computer simulation has been implemented to find the structure with improved stability. The result of the study shows that the relatively simple design alterations can eliminate most of the vibrations.

The productivity and the precision machining are the major concerns of the machine tools, and the importance of those features will be even more emphasized with the needs of the modern industries. In this paper the dynamic properties of a lathe have been investigated through the frequency analysis test and the computer simulation to minimize the transmission of vibration generated during the machining process. The modifications have been applied to the original structure to suppress the vibration transmission and further for the structure to achieve less vibrations and higher precision machining. The result shows that the machine can have much less vibrations with simple design alterations for minor expenses, the result can also be readily applied to many similar machines for improved stability.
