This paper presents the results following the researches concerning surfaces
kinematic generation using CNC machines.
The generation method of the revolutionary complex surfaces having three-
dimensional contouring (3D Generation Method) is modelled, using the die-sinking
EDM process.
The machining by spatial interpolation using disc electrodes is illustrated.
In this particular case the real surface profile generated by applying two correction
levels: tool correction and trajectory correction is numerically calculed.
The variation in time of the real error resulted in kinematic generation by EDM
is also underlined.
