Why Did You Become a CNC Machinist?

Becoming a CNC Machinist can be driven by several motivations, each uniquely compelling for various individuals. Many are drawn to the blend of engineering principles and advanced technology involved in CNC machining, finding the use of computer software to control machinery to be particularly appealing to those with a technological bent.

Others are motivated by the robust job prospects in the field, which boasts high demand for skilled machinists in industries such as aerospace, automotive, and manufacturing. The hands-on work involved, where tangible results are immediately visible, is also a significant draw. For many, the ability to solve complex problems during machining processes provides a rewarding challenge.

Financially, many CNC machinist positions offer competitive salaries and benefits, making it an attractive career choice. Additionally, the continuous learning opportunities within the field are an appealing aspect, as the industry is constantly evolving with new technologies and techniques.

A Personal Journey into CNC Machining

My path into CNC machining started after serving in the military. I worked for a shop that produced weapons and was looking for a job post-service. In that shop, I quickly excelled and was recognized for my skills, eventually migrating to the NC (Numerical Control) department as an Apprentice. Initially, it was just a means to earn a living, but I soon discovered that it came naturally to me and I enjoyed it. Despite finding it to be the highest-paying job I could get and that I was good at, I ventured into it out of necessity rather than a burning passion.

Early Apprenticeship in a Diverse Industry

My journey into manufacturing started in 1973, when I served an apprenticeship at a manufacturer of logging, marine handling, and fish processing equipment. I took an early programming class at a community college. One of my first experiences was programming a flywheel puller for a Briggs Stratton lawn mower engine, which was quite fascinating. During my training, the class visited a local CNC shop that had a reputation for being a "sweatshop." The foreman explained how the CNC lathe was the perfect tool because it never called in sick, took a bathroom break, or went on vacation. He even offered job applications, but out of a dozen attendees, no one raised their hand.

Reflections on the Decline of Machinist Roles

While I enjoyed getting to work with CNC lathes and mills near the end of my career, the landscape of machining has drastically changed. The skilled machinist who relies on their skill and experience to produce good parts by removing material from a workpiece is increasingly being replaced by 3D printing. This advanced technology deposits molecular amounts of material with zero waste, removing the need for human skills beyond programming. The future of machining is becoming less about standing in front of a machine to operate it and more about creating digital designs and overseeing the production process.

I am not recommending CNC machining as a career path for young people today. Instead, I advise them to consider roles in machine development, 3D printing, and other emerging technologies. Standing in a manufacturing line, pushing buttons, and letting robots do the work is a nasty way to make a living, and one that is highly susceptible to automation. Each industry is evolving, and future career paths will require different skill sets.
