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.
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.
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.
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.
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.
Ikya Global is one of the few best CAD/CAM training
institutes in Hyderabad that offer training at affordable prices along with
placement assistance and certification.
