
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.
What is Manufacturing
Engineering?

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

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 (DFMDFA)
 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)
Early Moving Assembly Line
at Ford

Robots at Work in Car Assembly
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





UmtPlusTM: 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
