Web2 Jan 2012 · A spring-loaded frame is used to apply the creep load of Method A. Either the spring is calibrated such that a given deflection is known to produce a given force, or an external testing machine is used to apply the desired force to the spring (and specimen). WebIn addition, the ploughing effect is less dominant in the machining of the unhardened steel specimen, as the spring-back effect seems to be strongly reduced due to lower process forces. In combination with the largest cutting-edge radius, the plastic deformation of the second pass is the main mechanism.
