  • Method for manufacturing spring and spring
    Patent number: 11965571
    Abstract: Provided is a method of manufacturing a spring for inspecting the stress distribution of the spring under load. The method for manufacturing a spring (1) includes the steps of applying a load to the spring (1), measuring the stress of the spring (1) under the load, and releasing the load applied to the spring (1), the measuring the stress of the spring (1) being made by measuring the stress on the surface of the active part of the spring (1) using X-ray diffraction with the cos ? method, and the method further including the step of determining whether the magnitude of the stress of the spring (1) meets a criterion.
