Program Options

Certificate programs typically take up to a year to complete.* Some are designed for beginners while others are aimed at people who already have some training or experience in machining. In many cases, credits from certificate programs can be applied toward an associate degree.

Diploma and associate degree programs can take up to two years.* They tend to be very similar, but an associate degree program usually includes a few additional general education courses.

Apprenticeship programs are also available. Going this route involves receiving in-class technical instruction as well as paid, supervised training on the job. Apprenticeships are often sponsored by unions, industry associations, or manufacturers. You can look for relevant opportunities through the U.S. Department of Labor.



Typical Courses

CNC classes typically cover topics such as:

  • Blueprint reading
  • Precision measurement
  • Machine setup, operation, and maintenance
  • Geometric dimensioning and tolerancing (GD&T)
  • Computer-aided design and manufacturing (CAD/CAM) applications
  • Multi-axis milling and turning
  • Programming
  • Shop safety

Skills You Can Learn

 Depending on the program you choose, you could begin learning how to:

  • Interpret blueprints and technical drawings
  • Calculate acceptable tolerances
  • Understand multi-axis machining concepts
  • Set up and operate CNC mills, lathes, and other tools
  • Write and edit programs
  • Use measuring tools such as calipers and micrometers
  • Inspect completed pieces for quality control purposes
  • Troubleshoot mechanical problems

Licensing & Certification

You do not need to be licensed or certified in order to work as a CNC machinist. However, voluntary certification from the National Institute for Metalworking Skills (NIMS) can help demonstrate your competence to potential employers. Many CNC school programs are designed to prepare their students for the NIMS assessments.

Some machine manufacturers and software companies also offer certifications related to their products. Here are two examples:

Education & Training FAQs

What kind of math do I need to learn for CNC machining?

You will definitely need to know basic arithmetic and how to convert between fractions and decimals. It's also good to have a solid understanding of algebra, geometry, and trigonometry. And being able to convert between imperial and metric measurements (e.g., inches to millimeters and vice versa) can be very helpful.

Will I be tied to a fixed class schedule?

Not necessarily. Some CNC machinist schools offer courses in a hybrid format, meaning that a portion of the instruction is delivered online and the rest is provided in person. And many offer flexible scheduling options that allow students to choose day or evening classes. It's worth researching CNC training near you to see what's available.

Earnings

The Bureau of Labor Statistics (BLS) classifies CNC machinists as CNC operators. For this occupation, the median annual wage is $41,200. The highest earners make $61,980 or more per year.

Job Openings & Outlook

Overall employment of CNC operators is expected to decline by 8.4 percent between 2018 and 2028, according to BLS projections. However, over that same time period, an average of 13,600 positions should still become available each year as people retire or move into different occupations.

Workers who have the skills to program CNC machine tools have a much brighter outlook. BLS projections show that employment of CNC programmers should grow by 20 percent over that same 10-year span.

Key Benefits

  1. The satisfaction of turning drawings into tangible parts: You get to use high-tech equipment to transform a block of material into a functional component for important industries like the aerospace, medical, energy, or defense sectors.
  2. The chance to solve problems in a creative way: The challenges involved in troubleshooting mechanical issues or figuring out the most efficient and effective method of creating a part means it's unlikely you will ever be bored.
  3. Advancement opportunities: After gaining some experience as a machine or setup operator, you could go after roles in CNC programming, shop supervising, or quality control.

What a CNC Machinist Does

CNC machinists use computer-controlled machine tools to manufacture parts to exacting standards of precision and accuracy—in some cases, within a thousandth of an inch. They most commonly work with metal, but they can also shape parts out of plastic, wood, and other materials.

 While job tasks vary somewhat depending on their specific role, typical duties include:

  • Studying engineering blueprints, drawings, and specifications in order to plan machining processes
  • Interpreting geometric dimensions and tolerances (GD&T) for each job
  • Calculating feed rates and machine speeds
  • Writing and inputting computer commands to make a CNC lathe, mill, or other tool perform the desired operation
  • Setting tool offsets, registers, and conditional switches
  • Preparing and loading material into machines
  • Overseeing CNC turning, facing, drilling, and cutting processes
  • Verifying that sample pieces adhere to expected standards
  • Making necessary adjustments to ensure quality production
  • Sharpening tools, replacing worn out components, and performing other preventive maintenance to keep machines working efficiently
  • Following all safety protocols

Work Settings

CNC machinists commonly work in:

  • Machine shops
  • Manufacturing facilities
  • Industrial plants

Careers

The CNC machining field encompasses a few different roles, such as:

Operator: Load raw materials into machines, calibrate equipment, adjust machine operating speeds during a run, and start and stop machines.

Setup operator or machinist: Enter the program into the machine, test and adjust the cutting tools, edit the program as necessary, and fix mechanical issues as they come up.

Programmer: Study blueprints, select the appropriate tool, and develop the code that tells the tool precisely how to create the part. CNC programmers typically spend most of their time in an office rather than on the shop floor.

Keep in mind that these roles often overlap, especially in smaller companies. For instance, it's common for job postings to call for CNC machinist/programmers to create the programs and set up the machines.
