![]() ![]() Further, the proposed methodology is demonstrated and validated by employing a real‐time casting part that was manufactured using the sand casting process. A detailed working flow process of the developed cost modeling system has been proposed under the guidelines of set‐based concurrent engineering. The system architecture is comprised of a user interface, knowledge database, and CAD modeling system. Therefore, this study attempts to integrate the set‐based concurrent engineering methodology into the development of a cost modeling system for the metal casting process. Set‐based concurrent engineering has emerged as an efficient solution to overcome this limitation as it provides simultaneous design procedures to positively assist the designer in achieving the required customer values in a short time and low cost. In recent years, the reliable, accurate, and timely estimate of product cost at the conceptual design stage can enhance the competitiveness of a casting part. The tool provides an idea of the implications of changing production factors, allowing the foundry to give accurate and fast responses without compromising its profits. In any case, the cost estimation tool presented in this work will allow for the optimization of the yield of the casting process rendering the involved company more reliable. ![]() It is observed that the influence of the drivers in the final cost of the pump is very dependent on the number of pumps to be produced. ![]() However, the developed tool is versatile and can be adapted to describe the casting process in other countries with different economies just by changing the input data accordingly. Therefore, the input data of the equations carefully consider the economic factors of this country. ![]() The mathematical expressions used for the calculation of the different cost drivers are presented and used to estimate the cost of fabricating the different parts composing a radial pump in a small Moroccan foundry. The drivers that most affect the cost of the process are identified in each step of the procedure, i.e., material, labour, energy, tools and general expenses associated with any industrial activity. This work presents a mathematical tool to estimate the cost of fabricating pumps by traditional casting. ![]()
