Recent developments in incremental sheet forming have resulted in the creation of novel manufacturing processes that are highly adaptable and could bring significant economic benefits for advanced technologies and low-volume production. In this manuscript, the following variables were examined: the variation in the deformation forces for a part with a pyramidal trunk shape; the variation in the deformations and thinning of the Al 3003 material during the incremental forming process; and the variation in the accuracy of the incrementally formed part and the quality of the surfaces (surface roughness). The components of the forces in the incremental forming have increasing values from the beginning of the process to the maximum value due to the hardening process. The TiN-coated tool ensures lower values of the forming components. Due to the kinematics of the forming process, deviations, especially in shape, from the part in the drawing are observed, which are shown by the radius of curvature of the side wall of the part, the appearance of a radius of connection between the wall and the bottom of the part, as well as dimensional deviations that are expressed by the variation in the forming depth. Concerning the smoothness of the surfaces, it was observed that the best roughness results were obtained in the case of the TiN-coated tool.
增量板材成形技术的最新发展催生了新型制造工艺，这些工艺具有高度适应性，可为先进技术和小批量生产带来显著的经济效益。在本论文中，研究了以下变量：具有金字塔形躯干形状零件的变形力变化；Al 3003材料在增量成形过程中的变形和变薄情况；以及增量成形零件的精度变化和表面质量（表面粗糙度）。由于硬化过程，增量成形中力的分量从过程开始到最大值具有递增的值。TiN涂层刀具可确保成形分量的值更低。由于成形过程的运动学原理，观察到与图纸中的零件存在偏差，尤其是形状偏差，这通过零件侧壁的曲率半径、零件壁与底部之间连接半径的出现以及由成形深度变化表示的尺寸偏差来体现。关于表面的光滑度，观察到在TiN涂层刀具的情况下获得了最佳的粗糙度结果。
