In order to prevent a router machine feed drive system from transient operational vibration, this paper presents vibration analysis and dynamic design optimization of a rack and pinion typed feed drive system for a router machine. The feed drive system was mathematically idealized as a 5-degree-of-freedom lumped parameter model. Stiffness parameters of motor-shaft, rack and pinion gears, and machine structure were appropriately considered in the modeling. Computational experiment was carried out to obtain vibrations of the feed drive system during its transient speed operation. Furthermore, optimum design parameters were successfully obtained by using a Genetic Algorithm based design optimization method.
