A dynamic synthesis model, which consist of a base, column, feed drive, and floor foundation, is developed for the enhancement of the performance of machining centers. By using this model, several countermeasures to enhance the dynamic performance are investigated. A thermal synthesis model is investigated for the fitness enhancement as well.(1)For the enhancement of the dynamic fitness, design strategies for anti-vibration of base-column-feed drive system are proposed. Improvement of the installation, reduction of the column mass, and driving scheme at center of gravity can provide good positioning accuracy.(2)By adding IIR filters in the velocity loop of the CNC-Servo system, positioning accuracy is improved without changing machine stricture. Second order der IIR filters are investigated to show their anti-vibration mechanism and performance. In the case of lower damping system, robustness is found to be major problems.(3)Dual actuation driving systems are investigated whether it can improve the dynamic performance of the total machine. The dual actuation system can improve the positioning accuracy without much increment of weight and cost, so it can contribute to the enhancement of the dynamic fitness.(4)Thermal synthesis is difficult to be established. In a ball screw on which thermal recourse moves and a high speed spindle, typical temperatures and thermal displacements are measured. Thermal distributions and displacements are modeled as the product of thermal modes and time functions in the stationary conditions.

开发了由基础，柱，进料驱动器和地板基础组成的动态合成模型，以增强加工中心的性能。通过使用此模型，研究了一些对策以增强动态性能。还研究了一种适应性增强的热合成模型。（1）提出了提高动态适应性的增强，提出了抗底柱供气驱动系统的抗振动的设计策略。改进安装，减少柱质量和重心的驾驶计划可以提供良好的定位精度。（2）通过在CNC-Servo系统的速度环中添加IIR过滤器，可以提高定位精度而无需更改机器狭窄。研究了二阶Der IIR过滤器，以显示其抗振动机制和性能。在较低的阻尼系统的情况下，发现鲁棒性是主要问题。（3）对双重驱动驾驶系统进行了研究，是否可以改善总机器的动态性能。双重驱动系统可以提高定位精度而不会增加重量和成本，从而有助于增强动态适应性。（4）很难建立热合成。在弹药辅助移动和高速主轴的球螺钉中，测量了典型的温度和热位移。热分布和位移建模为在固定条件下的热模式和时间函数的乘积。
