Influence of Milling Process on Internal Stress Measurement in Thick Plate
Layer removal method is executed by milling process, which may causes deformation and stress change of sample in aluminum alloy thick plate. Through error assessment about the experimental testing process involved milling, the milling stress layer is very thin and fail to change the whole stress dietribution of sample under some technique. Because many times of the loading - unloading operation will increase the deformation error of sample, per-depth of milling is should not be too small for the enhancement of accuracy of data fitting in stress measurement. Finaly, under the conditions of reasonable milling process and scientific experiments, influence of milling process on internal stress measurement can be ignored.
