Complex assembly procedures for joining components with plural fasteners are accomplished using predefined procedures for performing a multi-step assembly of a joint using a dynamically controllable assembly tool, or to inspect an assembled joint. An assembly tool is coupled with an electronically controlled regulator for reducing the tightening rate, or the load increase per impact for an impact or impulse tool, so the tool can be stopped precisely at a specified stopping load or torque. The predefined procedures for performing the desired tightening operation are established in a controller coupled with the electronically controlled regulator, for dynamically controlling the assembly tool. The system can be used to assemble joints involving multiple fasteners and which are subject to elastic interaction between the fasteners, rocking, or joint relaxation, and in assembly or inspection operations in which an operator is to be guided through a particular sequence of instructions. |
