To increase the service times of bolts for yield point control during parts processing, research was carried out on the bolt yield point control technology. The improvement was carried out to optimize the bolt installation parameters in several procedures, and the bolt had to be controlled within the elastic range. The experiment verifies that this technique is feasible and with this technique, only one set of bolts are needed for the manufacturing of one engine instead of two sets before, thus largely reduces the cost of production.
