A couple of decades back, the work of designing and
manufacturing was done separately, which was highly cumbersome and has so many
disadvantages. However, with the introduction of the CAD/CAM software
there has been an integration of designing and manufacturing processes. There
are several CAD/CAM online courses that can enlighten you on the several
CAD/CAM software that can be used to produce finished products, both designing
and manufacturing.
The numerous advantages of CAD/CAM have increased its demand
in almost every field, like civil, mechanical, architecture, and many more.
The use CAD and CAM enable automated transition from
designing to manufacturing, where CAD is concerned with designing and CAM with
manufacturing. Since, they both are used in combination, this has eliminated
the time gap between the two processes as well the duplication of the efforts
that existed in the traditional designing process, which proves out to be a
great advantage of CAD/CAM.
One of the greatest benefits of using computer aided design
and drafting software is the ease of manufacturing. Not just the use of CAD/CAM
saves time, but specifying the tools used to perform a particular job becomes
easy as all the drawings describing dimensions and materials for the job are
readily available from the CAD.
The programming has also become easier as all the data
related to the materials; dimensions, finish required, etc. are mentioned in
the final design of the product (provided by CAD) and can be used directly for
developing the program using CAM.
Before starting the actual manufacturing of the products,
their 3D models can be seen on your computer system and any kind of error in
designing and drawing can be eliminated before starting the actual
manufacturing.
The industry trend demonstrates a huge shift in working
methodologies with major U.S. companies already outsourcing their CAD/CAM needs.
By 2015, Forrester Research (a business analysis firm) expects over 3.3 million
jobs to be transferred from United States to other nations. Given the constant
boom in the automotive, construction and civil sectors, a career in CAD/CAM
field is highly promising for engineering candidates.
The phenomenal automation capabilities of CAD/CAM software
facilitate smoother and faster business functions. Used both for designing
products and automating the manufacturing processes, CAD/CAM applications
facilitate higher accuracy in the final output. CAD/CAM software is most often
used for machining of prototypes and finished parts.
In terms of deciding which software to learn, the decision
depends on the engineering field you come from – mechanical, civil or automotive.
