Multi Attribute Decision Making

The selection of a desirable machine is an important concern for the manufacturing firm. The selection process contains some critical selection attributes and the task of this process is to choose the desirable machine from a number of candidate machines. Then the machine selection problem is actually a multi-attribute decision making problem. This paper will develop a preference selection index method to solve the problem of machine selection in a flexible manufacturing cell. A case study is used to demonstrate that the proposed method is effective and feasible.

The authors of this paper aim to highlight the basic design of a flexible manufacturing cell destined for the final processing of water radiators used for AAVs, cell serviced by a serial modular industrial robot possessing in its kinematic chain structure three degrees of freedom, RRT SIL type. The paper outlines the concept, calculation and design of the (MRB) rotation module at the studied industrial robot’s base and of the (MT) translation module of the prehension device attached to the robotic arm. Depending on the organological elements that are part of the MRB rotation module and based on a rigorous dynamic study performed on robotic modules, modeling conducted with the help of Lagrangian equations of the second kind, a dynamic-organological calculation algorithm was obtained for the selection of the appropriate driving servomotor necessary to putting the rotation movable system into service. The last part of the paper deals with the flexible manufacturing cell, together with the calculations related to profitability, economy and investment return duration, following the implementation of the RRT SIL-type industrial robot.

Improve Production Efficiency

Rotary flexible manufacturing cell with multi-station automatic stretching is designed in this paper to meet the requirements of the machining process of cylindrical drawing parts as well as the needs of different stations for multi-drawing. The cell uses fixed circular disc worktable with multi-station. Each machining station has hydraulic stretcher to complete the drawing of the workpiece. Flexible manipulator finishes automatic loading and unloading among hydraulic stretchers. Gripper of manipulator with automatic center aligning and size control can grip workpiece in various sizes and has the function of self-centering. This equipment has completely realized all the stretching processes automaticly from feeding sheet metal to sending and forming workpieces. It can improve production efficiency and quality. It can also improve safety, reliability and cost efficiency. When replacing worked parts is needed, simply replace modular mold of every station in fixed circular disc worktable.
