3.4 Rapid prototyping application to complex surface products

In order to perform ISMF for complicated surface products with various wall angles, the designed products must ensure the ability to be formed according to the following specific conditions:


If it is found that there is a possibility of plastic destruction in a certain area, it is possible to conduct a simulation beforehand to check.

Figure 17 shows the simulation process and the obtained results after rapid prototyping of complex surface products by ISMF.

To verify and compare the accuracy of the final shape between simulation results, experimental products with CAD-designed surface in ISMF, we can use different sections and measure the shape distribution at different wall profiles and angles as shown in Figure 18. From that comparison, it can be seen that different deviations appear in the process of ISMF such as incorrect tool path generation, error due to tool radius, and error by springback and pillow effect.
