Abstract
The first benefit offered by all forms of CNC machine tools is improved automation. The
operator intervention related to producing work pieces can be reduced or eliminated. Many CNC
machines can run unattended during their entire machining cycle, freeing the operator to do other
tasks. This gives the CNC user several side benefits, including reduced operator fatigue. Fewer
mistakes caused by human error, and consistent and predictable machining time for each work
piece. Since the machine will be running under program control, the skill level required of the CNC
operator (related to basic machining practice) is also reduced as compared to a machinist producing
work pieces with conventional machine tools.
The second major benefit of CNC technology is consistent and accurate work pieces.
Today's CNC machines boast almost unbelievable accuracy and repeatability specifications. This
means that once a program is verified, two, ten, or one thousand identical work pieces can be easily
produced with precision and consistency.
A third benefit offered by most forms of CNC machine tools is flexibility. Since these
machines are run from programs, running a different work piece is almost as easy as loading a
different program. Once a program has been verified and executed for one production run, it can
be easily recalled the next time the work piece is to be run. This leads to yet another benefit, fast
change-avers. Since these machines are very easy to setup and run, and since programs can be
easily loaded, they allow very short setup time. This is imperative with today's. Just-In-Time
