Manufacturing of Non-Stick Molds from Pre-Painted Aluminum Sheets via Single Point Incremental Forming

Once scaled, the sections were drawn over them, which were used to measure angle #2. Besides this, the sections were compared with the theoretical profile of the mold. According to this law, the theoretical thickness can be calculated as a product of the initial thickness (1.20 mm) and the sine of the angle (45°). [...]it can be affirmed that the results obtained relative to geometrical accuracy in the dummy method are similar to those obtained in the incremental deforming processes of a single sheet. In the final stages, lower values of pitch and feed-rate will be used that will provide a lesser deviation in the real compared to the theoretical profile. Besides this, the exact angles and maximum depths that can be reached by sheets of this material with different thicknesses will be studied, using different values of spindle speed and different tool diameters.
