1. Computer Integrated Manufacturing
Yasir Hashmi 14ME-IND01

2. • Design is the human power to conceive, plan,
and realize products that serve human beings,
in the accomplishment of any individual or
collective purpose.

3. • Arts
• Architecture
• Fashion
• Gaming industry
• Engineering Design
• Mechanical Design

4. • Use of computer systems to assist in creation, modification, analysis and optimization of a
design.
• Computer assistance, while a designer converts his or her ideas and knowledge, into a
mathematical and graphical model represented in a computer.

5. A software system that uses computer graphics to assist in the:
• creation
• modification
• analysis of a design.
CAD has many different applications, which include:
• Designing new cars;
• Bridge and building design and testing; fitted kitchens
• Printed circuit board (PCB) design; aircraft.

6. Geometric Modeling & Visualization :
• Uses basic lines, curves, and shapes
to generate
1. 2D: Technical drawing & General-Purpose
drafting E.g. AutoCAD
2. 3D: Difficult to master & Freely rotate and
zoom a model
E.g. 3Ds Studio Max, Maya
Engineering analysis and design
analysis :
• Is also called computer-aided
engineering (CAE)
• Tests and analyzes designs on the
computer screen
E.g. AutoCAD

7. • Reduce the lead time in case of simulation
• Products can be tested more quickly
• Costly mistakes in design or production can
be avoided
• Time to manufacture can be reduced
• Documentation can be printed in various
forms for multiple users
• The quality of designs and the products
manufactured from them is improved

8. • Process of production of objects from metals
or non-metals, with or without application of
force, with or without application of heat,
with or without use of machines, joining or
removing of excess material.

9. • The use of computer software to
control machine tools and related
machinery in the manufacturing of work
pieces (a piece of any material under
process).

10. • Also refer to the use of a computer to assist in
all operations of a manufacturing plant,
including planning, management,
transportation and storage.
• CAM is a computer-aided process after CAD
• largest CAM software companies include:
• Dassault Systèmes, Siemens PLM Software,
Delcam, Vero Software, PTC, Tebis, Open
Mind Technologies, Cimatron
• Free CAM software: BlenderCam, PyCam

11. • Process planning includes the activities and
functions to prepare a detailed set of plans
and instructions to produce a part. Planning
begins with engineering drawings,
specifications, part list and a forecast
demand.

12. • Structures the data concerning part design,
manufacturing facilities and capabilities into
categories.
• CAPP is the method of automatically
generating the sequence of manufacturing
operations.
• CAPP provides the opportunity to produce
manufacturing routings which are rational,
consistent and even optimal.

13. • CAPP capable of understanding and
analyzing the part characteristics.
• It possess knowledge about machine tools,
cutting tools, etc..
• It possess the capabilities of analyzing the
interdependencies between part,
machining process, quality, cost.
• It possess multiple calculating capabilities.

14. Input based
on Solid
model
Processing
Output as a
process
plan

15. • Variant process planning
• Generative process planning

16. • This system works on the basis of group
technology and parts classification and
coding.
• Parts are grouped into the part families on
the basis of design and manufacturing
attributes. This parts are called master parts.

17. The steps are:
1. Enter the new part with part code the get
the process plan.
2. The CAPP program will search the
part family. If files contain identical
code then standard process plan is
retrieved.

18. • It is the system which creates plan by means
of decision logic, formulas and other logical
procedures.
• In this method process plans are prepared
from scratch without the assistance of human
and predefined plans.
• Input to the system includes the description of
the part in the form of part code number.
• After retrieving this information, the system
can generate the required processes and
process sequences for the work part.

19. 1. Geometry description and coding
component:
It involves all the geometric features for
all the process related surfaces together with
feature dimensions, locations, tolerances and
surface finish.

20. 2. Process knowledge database & decision
making logic:
The knowledge will be in the form of decision
logic. It is required to match the part geometry
requirement with manufacturing capability using
decision logic and data. It includes selection of
processes, menufacturing, equipments, work holding
devices, jigs & fixtures, inspection instruments, etc.
