2. WHATISCAD? CAD (Computer Aided Drawing/Drafting)
Basic : CAD is the implementation of digital computers in
engineering design and production.
Involved processes: Definition of a geometric model,
definition translator, geometric model, interface algorithm,
design and analysis algorithms, drafting and detailing,
documentation.
Requires : Design conceptualization and analysis.
Softwares : AutoCAD, Autodesk Inventor, CATIA,
SolidWorks

3. WHATISCAM? CAM (Computer Aided Manufacturing)
Basic : CAM is the implementation of computers in
transforming engineering designs into end products.
Involved processes: Geometric model, process planning,
interface algorithm, NC programs, inspection, assembly and
packaging.
Requires : Control and coordination of the necessary
physical processes, equipment, materials, and labour
Softwares : Siemens NX, Power MILL, WorkNC,
SolidCAM

4. ADVANTEAGESOFCAD
Minimizes the requirement for huge numbers of an
expensive draftsman in designing of a product.
It can be used directly in order to generate cutting
data for CNC machines.
Scaling, re-scaling modification in drawings and
models is easier and automatic and accurate.
Storage and retrieval of models is easier.
Design data can be shared in computerised
manufacturing management systems.
Precise 3D models can be examined before making
expensive materials.
It increases the speed of production and requires
less labour.
Multiple copies can be stored, printed and shared
electronically, which eliminates the need for storing
large paper drawings.

5. DISADVANTAGEOFCAD
Power cuts and viruses can be problematic for the
computerised system.
Industrial versions of the software could be very
expensive to buy especially for the startup costs.
Traditional drafting skills will be lost as they become
unnecessary.
Expensive training would be required to use the software,
which can be time-consuming and costly.

6. ADVANTAGESOFCAM
Manufacturing requires minimum supervision and can be
accomplished during unsocial work hours.
Manufacture is less labour intensive and saves labour
cost.
Machines are accurate, and manufacturing can be
repeated consistently with large batches.
Error occurrence is negligible, and machines can run
continuously.
Prototype models can be prepared very speedily for
elaborated inspection before finalising designs for
manufacture.
Virtual machining can be used to evaluate machining
routines and outcomes on the screen.

7. DISADVANTAGESOFCAM
It requires high initial investment and start-up cost.
Machine maintenance is also costly.
May result in loss of a workforce with high-level manual
skill.
To assure proper tooling and set up procedures it needs
highly trained operatives and technicians.
