Based on finite-element method and experiment research, rack performance of TK42300 CNC boring-milling machine was researched through analyzing static, dynamic and thermal features of the first design pattern. Weak link of machine structure de- sign was identified. After optimization, sample machine was trial-produced. The test result demonstrates the perforrnance of the ma- chine is good.机架是数控机床重要部件之一，对机床的精度有非常重要的影响。采用有限元分析和实验研究相结合的方法，对TK42300型数控龙门镗铣床的机架性能进行深入研究，分析首轮设计图样的静态、动态、热性能特征，识别机床结构设计中的薄弱环节，进行优化、改进后试制样机。实测机床性能良好，模拟设计取得了实效。
