The classical Lhemann-Filhes method solves graphically the problem of the spectroscopic binaries orbit determination through the radial velocities curve. In this paper, the useful properties of spline functions are used in order to formulate a method, similar to the classical Lhemann-Filhes one, which allows the use of the computer for obtaining the orbit automatically. An application to the pairs HD111980 and HD149414 is made.
