In this paper, it is the purpose to clarify the effect of a vertical displacement of the coiling pin as the influencing factors on the dimension of helical compression springs, and moreover to obtain the instruction to set up a vertical displacement of the coiling pin for forming them with highly dimensional accuracy. First, the effects of a vertical displacement of the coiling pin on the dimension of helical compression springs and on the initial tension of solid coil springs are analyzed by the differential geometry. Next, the experiments of forming springs are carried out in order to confirm the analyzed results. As the results, it is confirmed that the experimental results qualitatively agree with the analytical ones. Moreover, it is obtained the instruction to set up a vertical displacement of the coiling pin for forming helical compression springs with highly dimensional accuracy. Namely, helical compression springs can be formed with highly dimensional accuracy by setting up a vertical displacement of the coiling pin in the constant range of the initial tension of solid coil springs.
