摘　　要：在建立了形位公差国家标准之后,一般仍用尺寸公差或线轮廓度公差评定凸轮,用径向圆跳动公差评定凸轮的方法优于前两者,更适合于凸轮的评定。径向圆跳动公差评定时,凸轮的误差(测量)值和公差(评定)值都是径向值,便于测量、处理和评定,方法简便、直观。After the establishment of national standard on geometric tolerance, the dimensional or line profile tolerances are still adopted to evaluate the cam. To evaluate cam with radial circular run out tolerance is a better method than above-mentioned two methods. Because the value of measurement error and tolerance evaluation value are both radial values. It is easy to measure, treat, and evaluate and it is simple and visual.
