1. Basic CAD/CAM Training
Courses and Information

2. Introduction to CAD/CAM
CAD or computer aided design and CAM or computer-aided
manufacturing are two independent but interlinked aspects of
industrial computer applications. These are essential during the
chain of processes that take place during product development and
manufacturing, starting with initial design to final production.
CAD/CAM software have been saving lots of time and funds during
manufacturing, as compared to non-computerized manufacturing.
Because of their utility, many engineering students are taking up
CAD/CAM courses to keep up with industry demands.

3. CAD essentially involves the designing and creation of computer
models based on specific geometrical parameters. The designs, or
models, are visualised on a computer screen as a 3D representation
of an object or system. The objects can also be tested before the
actual production through virtual simulation of real-world scenarios.
Taking the process further, CAM involves the use of geometrical
design produced through CAD to control the manufacturing process
through automated machinery. Students taking CAD/CAM courses
get first-hand training in the entire product development process.

4. CAD/CAM Training and Relevant Software
Some of the CAD/CAM softwares often usedin the product
development process include AutoCAD, ProE, CATIA, DELCAM and
Unigraphics. Each of these courses has different functionalities that
require sufficient CAD/CAM training.
AutoCAD is a 2D and 3D modelling tool that is used for drafting,
drawing, plotting, solid editing, and imaging purposes. CATIA is
useful for surfacing, modelling, drafting and assembly. CAD/CAM
courses in this software involve design concepts, sketching, surface
and wireframe design, etc. The Unigraphics software is used for
drafting, modelling, assembly, surfacing and manufacturing.
DELCAM is used for milling and design.

5. Scope of CAD/CAM Courses
Companies are increasingly seeking out cost-effective
methodologies to design and develop new products. Therefore,
those with CAD/CAM training will find themselves amidst a lot of
industry demand. Those with this training can find jobs in various
professions, most common of which is industrial designing. To have
a successful career in the field, it is preferable to have a four-year
engineering or architecture degree which includes coursework
based on computer based designing. After the completion of a
CAD/CAM course, graduates can find employment in specialized
engineering and design service firms or big corporations such as car
manufacturers that regularly require design work.

6. Looking Forward
Almost all CAD/CAM software have overcome most technical
limitations with newer versions released every now and then.
A critical trend emerging now is the movement towards
standardization of software to allow inter-usability of data.
Companies are establishing standards for exchange of data to
ensure compatibility of designs. CAM/CAM software are now
starting to have more sophisticated visual representation such
as solid modelling, which is the more fully defined
representation of objects. Future software will also have
improved integration of modelling with testing and simulation.
CAD voice control software are also now being experimented
with the help of voice recognition technology to alleviate the
need for using a mouse or typing. It is thus advisable for those
with CAD/CAM training to stay open to learning as the
software keep evolving and new versions are released on a
regular basis.
