After the analysis of the issues concerning the efficiency’s improvement of the manufacturing systems, the module on Computer Aided Production discusses the techniques to assess the performances of the production processes and plan the products manufacturing. Specifically the module provides the fundamentals to analyse the manufacturing processes, to plan the manufacturing process by using CAD-CAM, and to assess the cost in function of the technologies and process organization.
The course is held in the second semester.
Review of the evolution of manufacturing systems and their organization.
The measurement of manufacturing systems. System model for the manufacturing process. Economical parameters for the efficiency assessment of the manufacturing systems. Methods of evaluating investment alternatives. Production and product cost. Upper-bound and Lower-bound approaches for transfer lines. Assembly systems and line balancing.
