Have you ever wondered how tools and gadgets you use are made with such precision? Every time you play a board game, assemble a piece of furniture, or see an acrylic sign, the odds are high that a CNC machinist had a role in its creation.
A CNC (Computer Numerical Control) machinist uses computers to control machine tools such as lathes, mills, and grinders to produce precision metal or plastic parts. The machinist is responsible for setting up the machines, writing and testing programs, and making necessary adjustments to produce just the right part. These machinists are like the superheroes of manufacturing, turning raw materials into parts and products used in everything from cars to smartphones.
Get an Early Start on a CNC Machinist Path
If this sounds interesting or aligns with the way your brain processes and studies parts, a job as a CNC machinist may be worth pursuing. Some people can begin prepping for a CNC machinist career as early as high school. If you are currently a high school student, some tips to get started include the following:
Focus on Math and Science
Classes in math, especially geometry and algebra, are crucial. Physics can also help you understand the principles behind machining.
Enroll in Shop Classes
If your high school offers shop classes, take them! They provide hand’s-on experience with tools and machines.
Computer Skills
Since CNC machining involves programming, taking computer science classes can be beneficial.
Join a Robotics Club
Participating in a robotics club can give you practical experience with designing and building things, which is similar to what CNC machinists do.
Make a Career Change
No matter how long removed from high school you are, there’s always a chance to gain new skills and make a career change. Specialized training to become a CNC machinist is available at technical schools or community colleges. Here are some details to know.
Certificate or Associate Degree Programs
These programs typically take one to two years to complete. They include both classroom instruction and hands-on training. You’ll learn about machine tools, blueprint reading, CNC programming, and quality control.
Expect to take courses in machining fundamentals, CNC operation, computer-aided design (CAD), computer-aided manufacturing (CAM), and metallurgy. These courses teach you how to operate and maintain CNC machines, as well as how to program them.
A significant part of the training involves working in a lab where you’ll get to practice using CNC machines. This hands-on experience is crucial because it allows you to apply what you’ve learned in a real-world setting.
Apprenticeships to Learn On the Job
In addition to formal education, many CNC machinists complete an apprenticeship. This is where you work under the supervision of an experienced machinist while continuing your education. Apprenticeships can last between two and four years and provide a great opportunity to earn an income while you learn.
During an apprenticeship, you’ll spend time both in the classroom and on the shop floor. This allows you to gain practical experience while also learning the theoretical aspects of CNC machining. Apprenticeships focus on developing a wide range of skills, from basic machine operation to advanced CNC programming and troubleshooting.
Completing an apprenticeship often leads to a certification that proves you are a qualified CNC machinist. This can make it easier to find a job and advance in your career.
CNC Machinist Certification
After finishing your education and apprenticeship, you might want to get certified. Certification isn’t always required, but it can help you stand out to employers. Organizations like the National Institute for Metalworking Skills (NIMS) offer certification exams that test your knowledge and skills.
Getting NIMS certified shows that you have the skills and knowledge to perform at a high level in the industry. It involves both a written test and a practical demonstration of your abilities.
An Ever-Evolving Career
Technology in CNC machining is always advancing, so it’s important to keep your skills up to date. Many CNC machinists take additional courses throughout their careers to learn about new machines, software, and techniques.
