f得最小基圆对应的坐标位置大约为（4080）经计算取偏距e40mm，r0894mm
f4滚子半径及凸轮理论廓线和实际廓线为求滚子许用半径，须确定最小曲率半径，以防止凸轮工作轮廓出现尖点或出现相交包络线，确定最小曲率半径数学模型如下：
dxd2dyd232dxdd2yd2dydd2xd2
其中：
dxddsdesi
s0scosdyddsdecoss0ssi
d2xd22dsdecosd2sd2s0ssi
d2yd22dsdesi
d2sd2s0scos
利用上式可求的最小曲率半径，而后可确定实际廓线。理论廓线数学模型：
fxs0ssi
ecosys0scosesi

凸轮实际廓线坐标方程式：
xxrtyyrtdxddxd2dyd2dyddxd2dyd2
其中rt为确定的滚子半径。根据上面公式，利用matlab编程求解，其代码如下：
