In anticipation of the Gaia astrometric mission, a sample of spectroscopicbinaries is being observed since 2010 with the Sophie spectrograph at theHaute--Provence Observatory. Our aim is to derive the orbital elements ofdouble-lined spectroscopic binaries (SB2s) with an accuracy sufficient tofinally obtain the masses of the components with relative errors as small as 1% when combined with Gaia astrometric measurements. In order to validate themasses derived from Gaia, interferometric observations are obtained for threeSB2s in our sample with F-K components: HIP 14157, HIP 20601 and HIP 117186.The masses of the six stellar components are derived. Due to its edge-onorientation, HIP 14157 is probably an eclipsing binary. We note that almost allthe derived masses are a few percent larger than the expectations from thestandard spectral-type-mass calibration and mass-luminosity relation. Ourcalculation also leads to accurate parallaxes for the three binaries, and theHipparcos parallaxes are confirmed.
