Stretch forming of sheet metal materials is a highly required process in aerospace industry for manufacturing skin parts. Automation of some processes such as cutting, punching, forming, shearing and nesting in conventional manufacturing tends to combine these forming methods. Some researches are made on the formability of sheet metal materials obtained in incremental forming process with stretch forming and water jet incremental micro-forming with supporting dies. This paper is an attempt to review the newly researches made on optimization of manufacturing metal skin parts to achieve geometrical accuracy.

The purpose of this research is to present an alternative method for manufacturing sheet metal parts using an asymmetric incremental forming process by means of an industrial robot. This method is based on designing, simulating and generating the toolpath for the tool attached to the robot using DELMIA software package. The proposed approach allows users to check for system collisions, robot joins limitations and singularity problems. After a comprehensive simulation of the movements of the robot is performed, the program code can be generated by means of a specific DELMIA function. The program can be used afterwards to control the robot during the experimental work. In order to demonstrate the capabilities of robot-forming, a truncated pyramid sheet metal part was manufactured using a custom made stand and with the help of a KUKA KR6 anthropomorphic robot.

The Comparative Study

Deep-drawing is an industrial forming process which allows the user to process large batches of sheet metals parts. One of the major drawbacks of this process is the complexity and the high cost of dies. In comparison incremental forming is a flexible process, allowing the user to obtain sheet metal parts without the need of using a die. The present paper aims to present a comparative study of the two forming processes by presenting the main advantages and drawbacks of each one. The comparative study, aimed on the industrial implementation of the incremental forming process requires a comparison of the two processes regarding the environmental impact. Thus, the results of the study will justify the selection of the incremental forming process in the case of small batches sheet metal parts in conditions of minimal impact on the environment.

Simulation Results

Surface flexible rolling method, using two integral working rolls as the forming tool, can achieve fast, flexible and continuous manufacturing of three-dimensional sheet metal parts. This paper introduces the basic principle of surface flexible rolling and discusses the numerical simulation results when the working rolls are bended as circular arcs. The stability indicates the forming effect to some extent and the flow type of the metal can be deduced from stability analysis. To integrate and analyze the simulation results by means of reverse engineering. The analysis results show that the forming process is stable and the effect of surface flexible rolling is fine. It also indicates that inhomogeneous deformation and accumulation occurs during the process. The numerical simulation and experimental results demonstrate that the surface flexible rolling is a feasible and effective way to form three-dimensional sheet metal parts.

Incremental forming is a promising manufacturing process which allow the user to obtain sheet metal parts, in a flexible manner, without the use of a die. However, the industry is still reluctant to apply the process on an industrial scale. Several drawbacks of the process which hinder its industrial implementation are reviewed in the paper. Among them, the low accuracy of the parts and the low productivity of the process are considered. The lack of dedicated technological equipment and specific CAM software tools are also seen as major drawbacks. Moreover, the lack of any analytical tools to predict the plastic behaviour of the processed part and to predict the moment when it loses its integrity influences the adoption of incremental forming on a large scale. Aside of summarizing these drawbacks, the paper tries to develop a decision-making system, based upon fuzzy logic, for assessing the degree of industrial implementation of the incremental forming process, if certain conditions are met.
