While absolute error estimates of surface stresses were limited due to strain gauge errors, the relatively larger difference on the curved surface is indicative of the limitations of a hexahedron FE model for representing such geometries.
Generally, the frequency domain errors of machined surface can be obtained by certain methods if the frequency domain errors in the cutting point are known.
Therefore, the DAD process does not put emphasis on the influence of cutting depth on the frequency domain errors of machine surface.
At last, the inertia tensor criterion which can decrease the waviness errors of machining surface was represented, and it can be applied to instruct the structure design of aerostatic bearing spindles.
Based on the analysis of the measurement data of the parts, empirical mode decomposition (EMD) method is used to decompose the machining errors into systematic and random errors, which are used to modify the numerical control (NC) codes to compensate for the systematic errors of the surface parts.
The correlation between the minimum pressure and maximum wind speed at Tacloban is 0.89, but the correlations between the mean errors of water surface elevation from measured inundation height and the minimum pressure or maximum wind speed are decreased to 0.60 and 0.34, respectively.
Validity of the models have been checked through experiments and the overall error percentages of surface roughness (Ra) and micro-turning depth deviation for validation experiments are 2.83 and 2.96%, respectively.
The paper presents a simulation tool designed to predict form errors of part surfaces obtained by face milling and turning processes.
Prediction errors of such surfaces have only been reported at a plot-level scale, but their application is invariably at a larger scale where prediction accuracy should be better.
By using thermal conductive paste, the uniformity of the surface temperature can be improved, and the error of the surface temperature measurement by FBG can be significantly reduced compared to that from a commercial thermal resistance surface temperature sensor.
