在很多轻工机械、机电一体化装置中，凸轮机构或凸轮组机构有大量的应用，由于凸轮轮廓与从动件是点接触或线接触，容易磨损，磨损后从动件不能按预期的运动规律进行工作，所以很有必要对凸轮轮廓进行测量并加以曲线拟合和误差分析来反映凸轮的现有状态。本文提出了一种检测方法，能够对凸轮表面磨损程度进行在线、非拆卸、直接检测，并可以对凸轮组之间的相对位置进行检测。对于检测结果，先利用非均匀B样条法对检测数据进行曲线拟合，再经过误差分析得出被测凸轮的理论曲线，进而确定误差值大小。该方法具有测量精确、易于操作、实用性强等优点，可有效反映凸轮轮廓状态。

The cam mechanism has a large number of applications in many light industrial machineries and mechatronics devices. Because the cam contact with a follower with a point or a line, it is easy to abrase and the abrasion can cause that the follower does not work as expected movement .In this paper, a detection method which can detect the abrasion degree of the cam surface online and non-demolition is proposed. For the data, the Non-Uniform Rational B-Spline (NURBS) is used to fit the curve and the theoretical curve is determined after error analysis,and then the error value is confirmed. The method is accurate,simple,practical and it is effective to show the condition of cam profile.
