After completion of the process analysis, it defines the process line, calculates the basic points' coordinates of parts profile.
在完成了工艺分析和确定了加工路线后，最关键的就是零件轮廓的基点计算。

After give out the coordinates of cam profile, the paper uses cubic spline interpolation to approximate the cam profile, which make theoryly result more practicable.
