Ecological Aspects

In contemporary industrial production the ecological aspects have increasingly important role in selection of sheet metal forming process. To produce sheet metal parts with minimal environmental burdening the shortening of forming processes including the procedures for production of appurtenant forming tools as well as decrease use of lubricant is prerequisite. The ecological aspects have to be considered also already in developmental phase where the forming technology is evaluated in digital environment with FEM simulations. In addition, particularly in small and medium batch production the geometrically complex parts are difficult to form economically with conventional forming processes like deep drawing or stretching. Therefore, new concepts like hydro-mechanical forming or incremental sheet metal forming were developed. In order to select the optimal forming process the production costs as well as the environmental aspects like lubrication, noise, pollution and energy per produced part have to be considered. The paper is focused towards the comparison of conventional deep drawing (DD) process aimed for forming the pyramid-shaped part with single point incremental forming technology (SPIF). The economical and ecological aspects affecting the successful forming by both concepts are determined. Comparative evaluation was established in order to present advantages and drawbacks of each analysed technology.

Design And Manufacturing

In incremental sheet forming processes, the expensive dedicated tool are avoided and replaced with a cheap and simple fixing device which support the sheet metal blanks. The current paper presents how a fixing device used for single point incremental forming device is designed, FEM simulated and manufactured. The fixing device can be used for parts with a cone frustum and pyramidal frustum made of DC05 deep drawing steel. The forces developed in the process and the device displacements were estimated using FEM simulation. The device components were manufactured using a CNC machines and the physical assembly is also presented in the paper.

Abrasive Finishing

In this paper the Magnetic Abrasive Finishing (MAF) was utilized after Single Point Incremental Forming (SPIF) process as a combined finishing process. Firstly, the Single Point Incremental forming was form the truncated cone made from low carbon steel (1008-AISI) based on Z-level tool path then the magnetic abrasive finishing process was applied on the surface of the formed product. Box-Behnken design of experiment in Minitab 17 software was used in this study. The influences of different parameters (feed rate, machining step size, coil current and spindle speed) on change in Micro-Vickers hardness were studied. The maximum and minimum change in Micro-Vickers hardness that achieved from all the experiments were (40.4 and 1.1) respectively. The contribution percent of (feed rate, machining step size, coil current and spindle speed) were (7.1, 18.068, 17.376 and 37.894) % respectively. After MAF process all the micro surface cracks that generated on the workpiece surface was completely removed from the surface.

Incremental sheet forming is a specific group of sheet forming methods that enable the manufacture of complex parts utilizing computer numerical control instead of specialized tools. It is an incredibly adaptable operation that involves minimal usage of sophisticated tools, dies, and forming presses. Besides its main application in the field of rapid prototyping, incremental sheet forming processes can be used for the manufacture of unique parts in small batches. The goal of this study is to broaden the knowledge of the deformation process in single-point incremental forming. This work studies the deformation behavior in single-point incremental forming by experimentally investigating the principal stresses, principal strains, and thinning of single-point incremental forming products. Conical-shaped components are fabricated using AA1050-H14 aluminum alloy at various combinations of fundamental variables. The factorial design is employed to plan the experimental study and analysis of variance is conducted to analyze the results. The grey relational analysis approach coupled with entropy weights is also implemented to identify optimum process variables for single-point incremental forming. The results show that the tool diameter has the greatest effect on the thinning of the SPIF product, followed by the sheet thickness, step size, and feed rate.
