INTRODUCTION
 Computer-aided manufacturing (CAM) is the use
of software to control machine tools and related ones
in the manufacturing of work pieces . This is not the
only definition for CAM, but it is the most common;
CAM may also refer to the use of a computer to assist
in all operations of a manufacturing plant, including
planning, management, transportation and storage.
HISTORY
 CAM evolved from the technology utilized in the
Computer Numerical Control machines that were used in
the early 1950s, which involved the use of coded
instructions on a punched paper tape and could control
simple manufacturing functions. Computer Aided
Manufacturing is a logical extension of that idea, as it
allows for a whole set of manufacturing functions to be
controlled simultaneously.
 The system’s primary purpose is to speed up the production
process of different components with more precise
dimensions and material consistency. In some cases,
Computer Aided Manufacturing uses only the required
amount of raw material, thus minimizing waste and
reducing energy consumption.

PURPOSE
 The primary purpose of CAM is to
speed up the production and
manufacturing process. It works sideby-side with CAD software so that
you can take designs directly from
CAD and use CAM to produce them.
In most cases, all you need to provide
are raw materials and instructions
like feed rate, speed and dimension.
BENEFITS OF CAM
 Improves Machining Capabilities: By using a CAD-
CAM system, manufacturers can improve their machining
capabilities.
 Improves Client Accessibility: The CAD-CAM software
allows manufacturers to receive CAD files from their
customers. After receiving these files, they can set up the
machining tool path, and perform simulations, which
helps them calculate the machining cycle times. The
software allows manufacturers to minimize errors, execute
projects easily, and deliver products to the market within a
shorter turnaround time.
 Helps Improve Productivity of CNC
Machines: Most CAM-CAD systems provide high–
speed machine tool paths, which help manufacturers
minimize their cycle times, reduce tool and machine
wear. High-speed tool paths enable manufacturers to
improve their cutting quality and accuracy.
 Helps Reduce Material Wastage: As CAM–CAD
software feature simulation features, it helps a
manufacturer to visually inspect the process of
machining. This allows him to capture tool gouges,
and collisions at an early phase.
