In this research, important mechanical characteristics of Compliant Press-Fit Pin and PTH are studied through the analysis of deformation mechanisms of Press-Fit Pin and PTH by elastic-plastic finite element method. The direct data for the optimal design of pin was obtained without interfere with the criterion on insertion force and retention force. Also, the insertion force and retention force of new type pin were measured by precision type tensile testing machine and it revealed good agreement with analytical results.<br/> In conclusion. it is believed that above results will contribute satisfactorily to the practical design of Press-Fit Pin.

Ultrasonic Machining process is an efficient and economical means of precision machining on glass<br/> and ceramic materials. However, the mechanics of the process with respect to crack initiation and<br/> propagation, and stress development in the ceramic workpiece subsurface are still not well understood.<br/> In this research, we investigate the basic mechanism of chemical assisted ultrasonic machining(CUSM)<br/> of glass through the experimental approach. For the purpose of this study, we designed and fabricated<br/> the desktop micro ultrasonic machine. The feed is controlled precisely by using the constant load<br/> control system. During the machining experiment, the effects of HF(hydrofluoric acid) characteristics<br/> and machining condition on the surface roughness and the material removal rate are measured and<br/> compared.
