CAM and CNC machines
CAM cannot reason. In this case, it cannot figure out the
right toolpath for mass production. Operators would still have
to select the type of tool to be used, the machining process
that should be followed, and the path to be used. This means
that the CAM cannot adjust to wear issues and sudden changes. It
needs to be reprogrammed to be able to work efficiently.
Furthermore, mass production increases the likelihood of errors
to occur in the production cycle.
Computer Aided Manufacturing started being used by automotive
and aerospace component manufacturing companies. This sped up
the manufacturing process and thus increased efficiency ratings.
However, the introduction of CAD into the industrial sector did
not eliminate the need for skilled professionals.
In fact, the operation of this program requires a higher degree
of skill in terms of being computer literate.
Flaws
The CAM system is a flawless solution. However speedy the system
becomes, it still has faults that may hamper production. Since
CAM generates a code for the least capable machine, an
improperly set CAM software required heavy manual editing. In
this case, editing such a code is a tedious and drawn-out
process that takes a lot of time and effort (something that
big-time companies cannot spare).
Another problem that you have to face is the data exchange that
has to take place when integrating CAM with other components
(CAD/CAM/CAE PLM). It becomes necessary for the CAM operator to
export the data in a more compatible data format. And since the
output stack of CAM is a G-code text file—sometimes containing
thousands of commands—the operator is then faced with a very
serious time problem.

PROS
CAM can cut cycle time significantly. This means that with the
proper people and the proper tools, a more efficient production
method can be obtained. A lower cycle time means that you can
produce more components in a lesser time. And since the main
users of CAM and CNC are big manufacturers with deadlines, it is
of the utmost priority to cut cycle time.
Another advantage that could be gained by CAM software is the
increase in machine life. Since the process is automated, the
system can keep track of certain variables that allow it to
adjust to the conditions of the machine that is operating under
it. This means that the life of the machine can be extended by
adjusting the performance of the machine in order to avoid
overworking it.
Quality can also be taken into account in this scenario. It is
because the system also monitors slight differences in the
production environment. Furthermore, the intricate designs that
cannot be achieved by human engineers can be achieved by the
machines. Also, these designs can be completed at a faster rate
compared to manual operations. Another factor that should be
considered would be the error ratio of the production of any
components.
Conclusion
So, CAM is a very important aspect of production. However, the
need for skilled operators still exists as programming and
setting up these machines decide the fate of the manufacturing
process. However, the increased automation and efficiency
provided by such a system makes programming and setting up of
these systems the only jobs of the operators.
This also allows operators to be more productive as they do not
have to watch any single machine for more than the required
amount of time.
