Subject fundamentals
The course analyzes the production system according to different aspects: management, technology and engineering .
The management aspect of the production system concerns the analysis of the production line, based on the queue models. The analytical models or the discrete event simulation, allow for assessing the performance of the line and for comparing the costs and benefits arising from the adoption of methods of control Push or Pull. It is possible to trace the evolution of the production system from its origins in the Fordís factory to the latest innovations of the Toyota production system and Lean revolution.
The technology of the production system mainly focuses on numerical control machining and related technologies. Starting from the definition of numerical control machine the course describes components, modules and manufacturing cells. The course also describes the numerical control machine (CNC) and the computer aided programming techniques. The description of industrial robots and their integration with the CNC machine allows to describe the automated manufacturing cells . The description of the coordinate measuring machines (CMM) for the testing of products allows to complete the analysis of the manufacturing cells.
The technology sector also deals with the non-conventional machining such as EDM , electrochemical machining , chemical milling , machining by ultrasonic , electron beam machining , machining with the laser and the techniques of rapid prototyping .
The industrial plant part of the course aims to discuss the main issues related to industrial facilities that future engineers might face during their professional activity. Also, it provides criteria to design and manage industrial plants with particular attention to the automotive industry.
Expected learning outcomes
The student acquires the skills needed to supervise a production system and to identify the production system more suitable for the specific application on the basis of management and technology.
The course provides an understanding of the major issues related to industrial plants. At the end of the course students will be able to define production layouts and to identify the characteristics of material handling systems and warehouses. Also they will know how to analyze the general requirements of an industrial plant.
Prerequisites / Assumed knowledge
Mechanical behavior of materials, Fundamentals of Technical Physics, Applied Mechanics, Mechanical Technology, Computer Aided Design.
