“…For example, in machining of titanium alloys and nickel-based alloys, it is concluded that further modeling studies are needed to create predictive physics-based models that are in good agreement with reliable experiments, while explaining the effects of many parameters [3]. However, the correlations between the process loads and surface integrity state variables or surface integrity parameters are hardly to be established quantitatively since a general relation independent from processes is not available to derive the dependence of surface integrity parameters on the various manufacturing processes, although many investigations have confirmed that different surface integrity states of manufactured components can be obtained by varying the process method and parameters [4][5][6]. The processindependent assessing of the various processes during manufacturing is more systematically concerned by Brinksmeier et al [7,8] with proposing a concept of process signature as a new approach to comprehensibly characterize the influence of machining processes on the material modifications generated in the component surface layer.…”

The inverse problem for surface integrity is still not solved in practice during high-performance component manufacturing, i.e., it is not possible selecting an appropriate process as well as process parameters in advance according to the given surface integrity required for the high performance. The desired surface integrity is usually created by trial and error based on an iterative approach due to lack of quantitative correlations between the loads of a process and the surface integrity variations during manufacturing. The inverse surface integrity problem is studied for manufacturing AISI 304 stainless steel components by employing an ultrasonic impact treatment (UIT) to achieve an enhanced fatigue performance. The correlations are explored between the process loads of mechanical impact, corresponding material loading within the treated component and surface integrity change in the surface layer due to surface modification. Based on experimental and numerical studies, such correlations of UIT process are identified primarily as the quantitative correlation between external mechanical load and material loading of strain and stress, and that between material loading and changes in surface integrity parameters such as residual stress and microhardness due to surface modification. It is demonstrated that a knowledge-based solution of the inverse surface integrity problem is possibly achieved by establishing the correlations to derive process parameters from a given surface integrity for manufacturing of high-performance components.

“…In the traditional size stamping process, the influence of various factors in the micro-stamping process is more obvious, such as friction factor, speed, depth and grain size. In the process of forming, there will be different deformation rules caused by the change of material size from the traditional macro-size, which called size effect [4][5][6].…”

Pure titanium TA1 foil with a thickness of 0.05mm under different grain sizes were carried out by the DT-C539 micro-stamping machine in the laboratory. The size effect of the pure titanium TA1 foil with grain sizes of 3, 7, 9 and 23 microns respectively on surface morphology of the microstamping sample were studied. It is found that the stamping samples with good surface quality can be obtained on the condition that the grain size is 23 microns and the stamping speed is 1mm/s. VORONOI model was established by using ABAQUS, NEPER and MATLAB software. Heterogeneous finite element simulation was carried out for the micro-stamping process under the same conditions. The results showed that the simulation results were more consistent with the experimental results.
