摘　　要：对HSK工具系统的定位精度进行了实验研究,揭示出夹紧力和刀柄锥面与主轴孔锥面之间阻力的相互依存关系及其对定位精度的影响。利用弹性力学理论和材料力学理论及有限元法对高转速下工具系统的精度进行了理论分析和数值模拟,指出增大夹紧力是保证高转速下HSK工具系统精度的关键,为确保高速加工可靠性和安全性提供了理论依据。Experimental researches were done with the positioning precision of HSK tool systems. Through these researches, the relation between clamping force and shank taper, the the influences of clamping-forces on positioning precision were shown. Based on theory of elastic mechanics and mechanics of materials and finite element method, theoretical analysis and digital simulation and calculation were done. The increase of clamping forces is the key to assure the precision of tool systems in high-speed machining. The paper offers theoretical basis for the reliability and security of high-speed machining.
