Why do we study MP II
Manufacturing processes are at the core of converting raw materials
into finished products. It helps understanding how goods are produced,
from the initial stages of material selection to the final assembly.
Conventional techniques: provides insights into conventional techniques
It allows students to specialize in specific areas of manufacturing, such
as metalworking, plastics processing, or advanced manufacturing….
Solving complex problems related to process, efficiency improvement,
highly valued in the manufacturing industry.
Courses include laboratory sessions or hands-on projects, allowing
students to gain practical experience with advanced manufacturing
equipment and techniques.

Lecture Outcomes
At the end of this lecture, student will be able to:
recognize and understand a broad range of manufacturing processes used in
the industry;
learn about common bulk metal deformation processes, sheet metal forming,
important non-traditional processes, and plastic fabrication processes.
What is Manufacturing ?
The word ‘manufacture’ is derived Manufacturing can be separated into
from two Latin words, ‘manus’ two subjects:
(meaning hand) and ‘factus’ 1. human’s discovery and invention
(meaning make). of materials and processes to
make things, and
The combined meaning is 2. development of the systems of
made by hand. production.
Manufacturing
In modern context, manufacturing can be defined two
ways,
1. Technologic manufacturing – the application of
physical and chemical processes to alter the
geometry, properties, and/or appearance of a given
starting material to make parts or products, and
2. economic manufacturing - the transformation of
materials into items of greater value by means of
one or more processing and/or assembly
operations

Manufacturing redefined
Manufacturing, a branch of industry which accounts for the application of tools
and a processing medium to the transformation of raw materials into finished
goods for sale.
Manufacturing can be defined as the transformation of raw materials into useful
products through the use of the easiest and least expensive method.

What Engineers Do?
Functions of manufacturing engineers are: Process Design and
Development
• to design the product and the process
Process Optimization
• to determine and define the equipment, tools, and processes
required to convert the design of the desired product in an Quality Assurance
efficient manner;
Cost Analysis and Cost
• to find out the most appropriate, optimal combination of Reduction
machinery, materials and methods needed to achieve
Equipment Selection
economical and trouble-free production. and Maintenance
A manufacturing engineer must have a strong theoretical and Continuous Improvement
practical knowledge:
Supply Chain
• in materials and up-to-date machinery, Collaboration
• to develop analytical solutions and alternatives,
Safety and Compliance
• managerial skill to solve open ended problems.

Whom to concern?
Manufacturing processes concerned to science and technology of manufacturing
products effectively, efficiently, economically and environment-friendly through:
• application of any existing manufacturing process and system,
• proper selection of input materials, tools, machines and environments,
• improvement of the existing materials and processes, and
• development of new materials, systems, processes and techniques.
Therefore, all manufacturing processes, systems, techniques have to be:
• Technologically acceptable • Economically viable
• Technically feasible • Eco-friendly

Classification of MPs
In manufacturing, the terms ‘top-down approach’ and ‘bottom-up approach’ refer to
two different strategies or methodologies for organizing and implementing production
processes. Here's a breakdown of each approach:
Top down Approach Bottom up Approach
» etch away material to make the » moving atoms around to create
products products
process is designed and organized
from the top level, and then
breaking them down into more
detailed plans and tasks.
starting from the lower levels, and
gradually building up to higher-level
processes and decisions.

Shaping and forming processes are fundamental techniques
used in manufacturing to transform raw materials into finished
products by altering their shape, size, or properties.
• Forging • Extrusion • Stamping • Rolling • Forming
Property-enhancing processes are techniques used to alter the
mechanical, physical, and/or chemical properties of metal
components or materials. These processes are often employed to
increase strength, hardness, durability, corrosion resistance, and
other desirable characteristics.
Surface processing operations are a diverse set of techniques used
to modify the surface of materials, typically to improve their
properties or prepare them for specific applications. These
operations can involve physical, chemical, or mechanical methods.
Material Removal Processes
A family of shaping operations, the common feature of
which is removal of material from a starting workpart
so the remaining part has the desired geometry.
Machining – material removal by a sharp cutting tool, Traditional
e.g., turning, milling, drilling, etc.
Abrasive processes – material removal by hard,
abrasive particles, e.g., grinding, polishing etc.
Abrasive process
Nontraditional processes - various energy forms other
than sharp cutting tool to remove material
