The study offers an analytical approach for assessing production control system performance in terms of volume and variety features of the product being manufactured for the Flexible Manufacturing System. Throughput, resource utilisation, cycle time, and maximum completion time are the four performance indicators taken into account. The objective is to quantify the production system's performance and define the reactive capability of production control architectures in a market that is becoming increasingly competitive. The examination of control systems' production performances motivates the evaluation of these architectures through the introduction of scheduling approaches that deal with uncertainty. Results revealed the semi-heterarchical control architecture outperforms the hierarchical control architecture through multiple performance criteria. A case study with regard to a manufacturing control system is presented in order to highlight the significance of our methodology and the contribution of the research.

This Paper presents the development of a flexible wire bending machine designed to overcome limitations associated with traditional counterparts. Traditionally, wire bending machines are often designed for specific purposes, necessitate complex coding, are prohibitively expensive, or are constrained to producing two-dimensional shapes. To address these challenges, our study begins with an extensive review of existing research in the field, followed by the selection of a concept derived from this analysis. The methodology encompasses the entire design and manufacturing process. Initial research guides the concept selection, which is then translated into a practical design using SolidWorks simulations. The theoretical foundation involves mathematical formulations for each machine component, ranging from the wire feeding system to the bidirectional and 3D bending mechanisms. Main actuators are chosen based on calculated parameters, and the machine is assembled, incorporating a CNC system. The machine is tested first without wire and subsequently with the bending of an aluminum (1350-H26), 3.2mm diameter wire, copper with 3.25 mm diameter and steel with 2.5 mm diameter. The Results demonstrate high accuracy performance and underscore the significance of considering spring back and bend allowance for precision in both 2D and 3D wire configurations. This study not only contributes to the design and fabrication of a flexible wire bending machine but also addresses the shortcomings of traditional counterparts, making wire bending more accessible, versatile, and cost-effective.
