“…During the SPIF, when the tool moves on the sheet, certain areas on the blank remain as unforced regions because of the helical path of tool movement. Therefore, these sections lead to the surface waviness [22]. In addition, tool movement in a local zone on the blank during the SPIF results in the surface roughness.…”

Flexibility and simple tooling make the incremental sheet forming (ISF) a great process to create complex shapes from mild steel sheets. It is a significant issue to reduce the surface roughness (SR) which is a weakness in the manufacturing of the mild steel parts in ISF process. SR has an adverse effect on the esthetic aspects of the mild steel products or their painting appearance. The purpose of this study is to investigate the effects of the ISF process parameters on the SR of the mild steel sheets. Feed rate, tool diameter, vertical step and spindle speed are chosen as four input variables in the experimental tests. Taguchi design of experiment and the analysis of variance(ANOVA) are used to optimize the SR by investigating the parameters effects and their interactions. According to the obtained results, the vertical step reduction and increase in tool diameter, decrease the roughness on the surface of the mild steel sheets during the single-point incremental forming. In addition, the tool speed (rotation and feed) has little effect on the SR. The results of a validation test demonstrate that the Taguchi technique and the ANOVA, effectively optimize the level of each variable to ensure the best SR.

“…The waviness of the items' treated surfaces, as well as their roughness and shape accuracy, all have a substantial effect on their service reliability [39]. As seen in Figure 7(b), waviness is a surface imperfection with a wavelength larger than the roughness [40]. Alternatively, surface waviness refers to low frequency imperfections on a surface that are overlaid with surface roughness [41].…”

Direct metal deposition (DMD) is a metal additive manufacturing (AM) process that builds objects layer by layer. The surface properties of DMD components are discussed in this study. The fluctuation of surface attributes such as roughness, finish, texture, and so on as a function of operation parameters has been investigated for a number of materials. This research assists in identifying the optimal process parameters for the material chosen, such as material feed rate, gas flow rate, and laser power, in order to generate the best surface characteristics. The results show that wire feed deposition surpasses powder feed deposition. The laser power and scanning speed of the laser were found to be the most influential process parameters. The study results reveal that the optimum process parameter combinations are material specific and is the keyfactor for obtaining better products with reduced surface roughness and waviness. The microstructural study also explores the material specfic effect in processs parameter combinations. This research could be used to determine or predict the best process parameters for a wide range of industrial materials.

“…Ham et al [3] carried out the influence of the diameter of the forming tool head on the surface quality of the forming part, and the study showed that under the condition of constant layer feed, the residual height between two adjacent layers' trajectories gradually increased with the decrease of the diameter of the tool head. Mohammad et al [4] conducted an experimental study on the process parameters affecting the surface corrugations of progressive forming parts. The study showed that the layer feed rate and tool head radius had a great influence on the surface corrugations of parts, while the feed speed and spindle speed had little influence.…”

In order to reduce the corrugations of pieces and improve the surface quality of pieces in single point progressive forming (SPIF), the forming process parameters were studied. Aiming at the complexity of single point progressive forming process, the prediction and analysis models of different process parameters, surface corrugateness and geometric deviation of inclined straight wall parts were established based on the response surface method by Box Behnken Design method. The reliability of the prediction model was analyzed by ANOVA (variance), and the influence law of process parameters and evaluation index was analyzed. The optimal process parameter combination is obtained and the accuracy of the model is verified. The results show that the layer feed of inclined straight wall parts is the most significant factor affecting the surface corrugations of parts, and then the influence degree from weak to strong is the diameter of tool head and forming Angle.
