Computer numerical control machines (CNC) are all the rage in the production/manufacturing arena, particularly in companies that manufacture metallic and non-metallic parts. Of course, someone is needed to expertly run and maintain these machines so that they work optimally. CNC machinists are specially hired to do this as they are trained in operating CNC machines – for both conventional and special purpose fabrications.
Eligibility criteria to work as a CNC machinist is usually an associate’s degree from a college or a technical school – many CNC machinists are also hired if they have a high school diploma and some related experience.
A couple of years of experience working with CNC machines will make it possible for you to obtain an immediate position, owing to the skills you may have developed during this time. Reasoning ability, mathematical skills and ability to read and interpret sketches, blueprints and manuals is a prerequisite for this position.
Physical ability is essential for people working as CNC machinists as they are often required to stand for long periods of time and work with their hands. Since one is exposed to moving mechanical parts, while at work, it is important for CNC machinists to be aware of what is happening around them constantly.
If you are interested in working as a CNC machinist, you might find the following job duties interesting:
CNC Machinist Duties & Responsibilities
