Abstract

Distortion amounts .delta.1, .delta.2, .delta.12 of workpieces are measured. Based on these distortion amounts, those correction amounts A1, A2, A3 for correcting the workpieces which are required to eliminate the distortions after the workpieces have been combined are computed. Clamp units are moved to thereby deflect the workpieces by the correction amounts. In this state, the workpieces are combined.
