NURBS blend curve

 I'm working on a design using a planar cam, where the cam follower follows one circular path, them moves outward to another radius, then back in again.  I have circular arcs for the inner and outer segments trimmed to where the constant radius sections end, and I added a NURBS blend curve to join them... it curves out very slightly coming off the inner arc, then bends around to be tangent to the outer arc.

The question is, will a NURBS blend give the minimum acceleration to the cam follower or is there a better way to construct the path?
