Problem: Creating a Barrel Cam in Solidworks

Hello everyone
I'm working on a project which is making barrel cam profile,
for making barrel cam I have 2 pairs of 3d spline, each pair make a 3d plain as a support for the follower.
The problem is when I'm trying to make a plain between this splines a deviation about 1 degree will be added, In other words Solidworks make a small slope in plains which make it impossible for CNC machine to create the part
how should I correct this little deviation in plains?

You can make it by using a split line and surface to create the path for cut-sweep, that is it.

Not sure what I am doing but this could be a way
