CNC Machinists and Operators are relied on to mass-produce products that conform to very specific requirements. Thus their work must be meticulous, even under pressure to meet deadlines. They have to take into consideration multiple factors, including what metals to use and how best to cut or shape them. Factories can be loud and dangerous, requiring workers to wear protective gear, such as goggles and hearing protection. 

They need to carefully follow safety procedures to avoid injury to themselves or others in the area. The day-to-day job requires plenty of stamina because workers are usually on their feet, often in a bent or leaning positions. The repetition of machining parts can get monotonous after a while, but workers have to keep their focus because of the inherent hazards of the job. There can be long periods of working alone, so Machinists sometimes need to look beyond their place of employment for socializing.  

There are many CNC machine trends shaping the future of the industry. One is the development of machines capable of higher speeds, including faster spindle speeds, faster feed capacity, faster computing, and faster tool changing. These increases don’t diminish precision, because CNC machines are getting more accurate at the same time! 

Along with these advancements, 3D printing is starting to share some of the workloads to make parts that CNC machines finish. Another change is the use of digital twins which “duplicate a CNC machine and its environment, including its setup on the shop floor, within the CAM software, providing accurate toolpath simulation” in order to “reduce or eliminate any surprises that may occur during the machining process.”

People who get into machine-related career fields usually enjoy working with their hands and feel comfortable using tools and stationary heavy equipment. They might have enjoyed math and computer programming courses in high school or liked doing projects in shop classes. 

Machinists can collaborate with others but don’t mind being on their own for long periods. They might have been very independent growing up and may have always wanted a job where they have some freedom to do their work without a lot of interaction with others.
