Recentoly, as a product with complex form increase for multiple functions or high quality, a worker must machine and assemble some parts with high precision. Especially, if worker assemble the plural parts with high positional or high attitudinal deviations, long time and high cost are necessary. Therefpre, in this paper, a tightening system of bolt for assembling during plural machining was developed. This system consists of a tightening shank of bolt for assembling some parts and a bolt stocker for supplying some bolts to the tightening shank. The tightening shank of bolt can be installed in the main spindle by the automatic tool changer. After one part A is finished with a machining center, the tightening shank of bolt takes out some bolts from the bolt stocker, and can tighten with some bolts between the part A and another part B. The part B is supplied by a robot. At last, the part B is finished with the machining center. This system was evaluated by the experiments of positional and attitudinal deviations ; these are parallelism, squareness, concentricity and position between two parts. It is concluded from the results that ; (1)This system can assemble the plural parts with high positional and attitudinal deviations. (2)A product with complex form can be made with short time and low cost.
