Manufacturing Engineering An Introduction via Examples What is Manufacturing Engineering ? An Early and Modern Example about Manufacturing: Car Assembly A Modern Example about the truck manufacturing company
What is Manufacturing Engineering? Electrical Engineering – to engineer an electrical product or system. Computer Engineering – to engineer a computer or a system of networked computers. Mechanical Engineering – to engineer a mechanical or thermal product / system. Manufacturing Engineering? To engineer the process or a system that results in a manufactured product.
Important: To design the manufacturing process or system with efficiency and quality Process Design: Desing the sequence and detailed steps to manufacture a product using manufacturing methods (machining, forming, etc.) Manufacturing System Design Desing the manufacturing system with highest efficiency, such that the manufacturing competitiveness is met Manufacturing Management Toyota Production System (TPS) Lean Manufacturing Computer Integrated Manufacturing What is Manufacturing Engineering?
İMALAT MÜHENDİSİ: İmalat süreçlerini, kaliteli ürünlerin ekonomik olarak üretimini sağlayacak şekilde planlayan mühendis
İMALAT MÜHENDİSİ ANA GÖREVİ: Ürünlerin tasarım spesifikasyonlarının belirlenmesinden, bunların imalatları sonrasına kadar olan dönüşüm süreçlerini yönetmek ve bu fonksiyonu bulundukları kuruluş içinde optimizyonu sağlayarak icra etmek
İMALAT MÜHENDİSİ ANA AKTİVİTELERİ: Süreç (Proses) Tasarlama İmalatta hangi yöntemlerin hangi sırayla uygulanacağını belirlemek, Yöntemlerin uygulanışı sırasında kullanılacak takımları belirlemek, Kullanılacak donanım (makine) ve sistemleri seçmek Seçilen imalat yöntemlerinin, takımların ve ekipmanın maliyetini belirlemek.
İMALAT MÜHENDİSİ ANA AKTİVİTELERİ: Problem Çözme ve Sürekli Geliştirme İmalat süreçlerini yönetme veya destek verme, Ürün geliştirme, maliyet azaltma, verimliliği arttırma gibi konularda destek verme.
İMALAT MÜHENDİSİ ANA AKTİVİTELERİ: İmalata/Montaja Uygun Tasarlama (DFM- DFA) Ürün tasarım mühendislerine imalata uygunluk yönünden (teknik sorunları çözme, düşük maliyetle en kaliteli ürünü en kısa zamanda üretme vb.) danışmanlık yaparak destek verme.
What is Manufacturing Engineering? The manufacturing engineering discipline has very strong overlaps with mechanical engineering, industrial engineering, materials management, and operations management
What do Mnf. Eng. do Design manufacturing processes and systems Develop automation for high productivity Develop production schedules and establish inventory levels Ensure product quality is maintained Develop software that analyzes data, controls equipment and unites the production system Design the job itself, so that it conforms to the capabilities and limitations of the human operator and ensures the workers' health and safety
An Early and Modern Example about Manufacturing: Car Assembly The original “work cell” assembly method Henry Ford’s idea of assembly line, following the efficiency innovations in cattle slaughtering Many innovations for higher efficiency and better quality, including robotics The Toyota Production System (TPS), practiced at many automotive companies)
A Modern Car “Assembly Line” VW Phaeton in Dresden
Sample Project: ATruck Manufacturing Plant Goal: Double the amount of truck they manufactured in a day, by optimizing their resources while maintaining excellence in quality One of the objectives of the study was To know the precise amount of time spent on non value adding tasks at each truck assembly station, in order to optimize their operation Required to evaluate 70 assembly workers
Beyond the Stopwatch Work measurement studies often use stop watches to collect task times Difficulty Hold the stopwatch and write the information at the same time The results are not accurate Data collection not easy
State-of-the-Art Software UmtPlus TM : The highest quality work measurement tool that leverages handheld computers This software developed by Laubrass, facilitates and optimizes the data collection process Just need to click on the appropriate icon and your time is logged Easy to use Truck company customized to suit their needs
Results Two hours of training in using UmtPlus to collect the necessary data Evaluated 70 workers in just three days Once the tasks have been accurately timed on the PDA the results are uploaded to the computer without having to do any data entry Employees prefer to see the PDAs rather than a stop watch
Manufacturing Engineering Education Many programs throughout USA and Europe: Penn-State Missoury University of S & T Virginia State U. Northwestern U.
Manufacturing Engineering Education Typical curriculum includes: Statics and dynamics Strength of materials and solid mechanics Instrumentation and measurement Thermodynamics, heat transfer, energy conversion Fluid mechanics and fluid dynamics Mechanism design (including kinematics and dynamics) Manufacturing technology or processes
Manufacturing Engineering Education Manufacturig Planning and Control Manufacturing Systems Design Hydraulics and pneumatics Mathematics - in particular, calculus, differential equations, statistics, and linear algebra. Mechatronics and control theory Materials Engineering Drafting, CAD (including solid modeling), and CAM etc.
