摘　　要：为了掌握凸轮轮廓线的特征函数,加快消化和吸收国内外凸轮先进设计技术,介绍了近年来凸轮反求的研究方法,指出了数据处理在凸轮反求中的作用,分析了数据处理的必要性,阐述了数据处理的一般方法及逆向CAD软件数据处理的局限性。针对传统反求方法中存在制造误差、使用误差及测量误差,导致所反求的数据与原始凸轮精度有出入的问题,提出了以名义速度、名义加速度及名义跃动来分析凸轮轮廓线的运动规律,并给出了其数学求解依据,绘制了数据处理流程图,并通过凸轮轮廓高精度反求实例验证了论文方法的可行性,应用效果的显著性。In order to work out the eigenfunction to promote the assimilation of the advanced designing technology both at home and abroad, introduction is given to the methods of back seeking precision cam profile in recent years while the importance of the data processing in the back seeking process. Indispensability of data processing is highlighted when general methods of data processing is introduced with the limitation of the back data processing of CAD software. Considering the errors of the conventional back seeking method regarding the manufacturing error, application error and test error, resulting in the inconsistency of the data between the primal data and the back seeked data,it is pointed out that analysis of the motion law of the cam profile can be done with nominal speed, nominal acceleration and nominal bounce. The mathematic solution is given plus the data chart. The practice of the back seeking process attested to the feasibility of the paper and the significance of the application.
