Abstract
The invention relates to a method for assembling sheets by riveting, comprising a step for piercing a hole through the sheets, followed by a step for placing a rivet in the pierced hole, the step for piercing a hole being executed by supplying an advance speed instruction of a piercing tool as well as a rotation speed instruction of this tool. According to the invention, a previous step for determining information on the local stiffness of the sheets (Info_stiffness) is also carried out at the level of the hole to be pierced, the advance speed instruction and rotation speed instruction of the tool being a function of this information on the local stiffness of the sheets.Application most suited to the field of aircraft construction.
