Static and dynamic calibrations and actual cutting tests have confirmed that the main performance figures of the dynamometer meet the specifications recommended by CIRP.

经静态及动态的标定和实际的切削试验证实，该测力台的主要性能指标符合CIRP的规定。

The two different definitions of the axis of rotation are discussed. One is the definition of the CIRP text and the other is that of the instantaneous center of rotation.

评论了机床主轴转轴的两种不同定义，其一是CIRP统一文件的回转轴线定义，另一是瞬时回转中心线的定义，指出这两种定义均有不妥之处。
