Abstract:

Various shot-peening procedures for the manufacture of cold-wound helical compression springs were investigated to establish optimum shot-peening methods to increase the life endurance properties of springs. Production springs that are typical of small arms applications were fabricated from music wire and stainless steel materials. The springs were given different shot-peening treatments with the exception of control groups that were not shot-peened. Effect of the various shot-peening procedures on spring life was evaluated by laboratory endurance tests. Recommended shot-peening procedures based on test results are given for the spring materials and stress conditions investigated in this project.
