The primary purpose of the present research is to analyze and determine the impact that expansion and shear exert on the production time, expenditures on materials and consumable items, i.e., production costs, and the cost of the manufactured sheet material details. An applied study was, accordingly, conducted to investigate the implications of different design features and shear on a sheet material workpiece, i.e., the base of a water tower, with respect to the shear line produced during surface segmentation. In order to determine in which direction and to what extent the dimensions of the constituent elements influence the expansion, a graphical experiment was performed with a smaller width of the elements than the surrounding surface, as well as with two different steps. Cases are presented and analyzed in which the surrounding surface is considered as composed of several composite belts in horizontal and vertical arrangements of the metal sheets. The research findings refer to the sheet material parameters (thickness, dimensions), production technology principles, and their effects on the technological process to optimize material costs and reduce waste in manufacturing. The study revealed that in order to achieve optimal shear outcomes, it is recommended to manufacture all the segments concurrently, and shorten the time of production by programming the process of shear to minimize the length of the shearing lines while segmenting the surfaces of the relevant details. This will be more suitable in the case of constructions executed along helical lines, applied with a small step, where the residual material is of more compact dimensions with a suitable cut.
