Lifting table has been designed and developed through the concept of Learning Factory (LF) at the University of Mostar. The idea for lifting table design has come from the local industry needs for a lifting platform that should lift a man and/or load at a certain height. For safety reasons, design is checked under the loading using a method of finite element analysis. The paper predicts and explains methodology for structural analysis used in presented case study. Results of FEM analysis are basis for making ways and guidelines to optimize current design in order to get optimal parameters for weight, stability, capacity, mobility and layout of the lifting table.

Layered manufacturing technology allows rapid production of parts, which can be used for various engineering evaluation and analyses. For that reason, there is a need for developing an expert tool to fully implemented analyses of a CAD model at the some phases of design process. This paper introduces multi criteria decision based on intelligent advisory system. Knowledge base contains collected experts recommendations from functional, aesthetic and ergonomic field. These recommendations are improving model characteristics for its better exploitation. The ultimate goal of this expert tool is to provide the highest level of advice, depending on the limitations, such as surface quality, time production, manufacturing, assembling, or geometrical complexity. This model system should be applicable for the most CAD models. A case study with the electrical switch is carried out in order to show usefulness of application for specific problems in the layered manufacturing process in order to get better final part. The results obtained from a case study are implemented through 3D Print Technology.

The fundamental basis for implementation of reengineering is: experimental measurement of forces and torques on the rollers-tools production line for profile sheet metal forming. The paper presents the experiments of measuring forces and torques, modeling and simulation in the aim of redesigning the process of sheet metal forming, selecting of the optimal process of sheet metal forming for each forming module and totally for the production line and increasing productivity on production lines. In the experimental research forces and torques were measured on the rollers of forming modules for profile forming of sheets for different values of the input parameters of the process: material type σm, sheet thickness s and sheet width b. Based on the experimental results mathematical models were defined, which enabled the analysis and implementation of reengineering the production system.
