What is Production Engineering
?
Is a combination of manufacturing technology.
Production Engineering Include The Application Of Metal Cutting,
Machining Processing, Castings, Joining Processes, Tool Design,
Metrology, Machine Tools, Automation, Jigs And Fixtures, Die Design,
Material Science, and Forming.

In
Mechanical Engineering:
A machine is a group of mechanical components
assembled together to perform a specific function.
These components are first designed then
manufactured according to
“The Product Cycle”

A. Joining Processes
B.1) From Liquid (Casting)
one of the oldest manufacturing processes.
metal casting involves filling a mold with molten material.
This material, upon solidification, takes the shape of the
mold.
14
B. Same Material
Advantages
Metal casting can be used to make parts with complicated
geometry, both internal and external.
15
Metal casting can produce very small parts like jewelry
16
Parts weighing several hundred tons, like components for
very large machinery.
17
Disadvantages
The final product tends to contain more defects.
The product has a lower strength and ductility compared to
that of other manufacturing processes, such as metal
forming.

B.2) From Solid Blank
Metal Forming Processes
B. Same Material
Forging
16
Metal And Alloys Are Deformed To The Specified Shapes By
Application Of Repeated Blows From A Hammer.
21
Products By Forging
Connecting Rod
Crankshaft
Extrusion
Extrusion is a process in which the metal is subjected to plastic flow
by enclosing the metal in a closed chamber in which the only
opening provided is through a die.
Products By Extrusion
DRAWING
The Process Of Producing The Wires Of Different Diameters Is
Accomplished By Pulling A Wire Through A Hardened Die Usually
Made Up Carbide.
In Machining, A Manufactured Part Is Created To Its
Desired Geometric Dimensions By The Removal Of Excess
Material From A Work Piece, Via A Force Exerted Through
A Certain Material Removal Tool.
C. Subtractive Process
Machining
26
D. Additive Manufacturing?
Physical Model
Rapid prototyping is a technique for direct conversion of
three dimensional (3D) CAD data into a physical
prototype.
27
3D - Solid Modeling
28
Applications
29
parts having complex geometry can be produced.
Assembled parts can be produced in one operation.
The fabrication can proceed with little intervention.
There is no need for jigs or fixtures.
Reduced lead times and cost to produce prototype
components.
Advantages of RP :
30
Disadvantages of RP
Limited variety of material.
Part volume is generally limited.
Part accuracy: Stair case appearance for sloping surface
For metal parts. large production runs or simple objects ,
conventional manufacturing techniques are usually more
economical
Aside these limitations, RP is still a remarkable technology.
Objectives in Manufacturing :
Reducing The Manufacturing Time
Reducing The Manufacturing Cost
Maximizing The Production Rate
Maximizing The Profit Maximizing The Profit Rate
