“…These prototypes are generally made in the course of different research investigations but there are some SMEs and research centers where parts can be ordered and then produced within days or weeks (depending on the complexity of the part). When a metal or polymer sheet is formed using ISF, the forming tool which is carried by an industrial robot or CNC machine [9] makes an indentation in the sheet and follows the tool path of the desired part. This process step (local bending and stretching) is repeated all along the tool path until the final depth and form of the part is reached.…”

Abstract:Incremental Sheet Forming (ISF) is a technology suitable for manufacturing small series and single products. Due to the high customization potential of this process, it is therefore necessary not only to implement the mechanical tools and control algorithms needed, but also to enable easy integration with product configurations executed by customers. The paper describes how ISF can be provided as flexible manufacturing service to production networks and how it can be configured by means of appropriate service descriptions. Furthermore, a new adaptive tool path control algorithm at process level is introduced to bypass fracturing due to localized thinning.

Abstract. Nowadays the customer requirements are in permanent changing and according with them the tendencies in the modern industry is to implement flexible manufacturing processes. In the last decades, metal forming gained attention of the researchers and considerable changes has occurred. Because for a small number of parts, the conventional metal forming processes are expensive and time-consuming in terms of designing and manufacturing preparation, the manufacturers and researchers became interested in flexible processes. One of the most investigated flexible processes in metal forming is incremental sheet forming (ISF). ISF is an advanced flexible manufacturing process which allows to manufacture complex 3D products without expensive dedicated tools. In most of the cases it is needed for an ISF process the following: a simple tool, a fixing device for sheet metal blank and a universal CNC machine. Using this process it can be manufactured axis-symmetric parts, usually using a CNC lathe but also complex asymmetrical parts using CNC milling machines, robots or dedicated equipment. This paper aim to present the current status of incremental sheet forming technologies in terms of process parameters and their influences, wall thickness distribution, springback effect, formability, surface quality and the current main research directions.

“…Vanhove et al [12] confirmed that the increase in feed rate has a positive effect on ductility and increases the maximum forming angle. Callegari et al [13] performed several experiments to validate the complex methodology for system design and prototyping. The important parameters are types of materials, number of axes of the task, the kind of interpolation between the points, the path imposed to the tool and the size of punch.…”

Sheet metals forming process is widely used in consumer and industrial products. However, the conventional sheet metal forming has low flexibility and product quality. It also prolongs the time-to-market in producing prototype products that required low costs. Single point incremental forming (SPIF) is one of relatively new sheet metal forming process. The increase interest in new techniques for forming processes and the usage of robotics in the industry has created more researches on the SPIF. Robot-based SPIF is a method of deforming a sheet metal to create designed workpieces by utilising a forming tool that attached to an industrial robot. In this present work, an optimization study for combination of process parameters in robot-based single point incremental forming of aluminum alloy sheet was experimentally investigated using Taguchi method to achieve an excellent surface roughness. A number of forming experiments were conducted using the L18 orthogonal array. Analysis of Variance (ANOVA) was used to identify the most significant process parameters affecting the surface roughness. The results analysis indicates that the optimum process parameters for surface roughness are obtained as 0.3 mm of step size, 150 mm/s of robot speed and 45 degree of wall angle. The most significant process parameter is step size and followed by robot speed. The study revealed the surface quality could be improved by proper selection of process parameters.
