Are you tech-savvy, detail-oriented and always up for a new challenge? A CNC machinist career may be right for you. As a technician, you can apply your knowledge and skills to a variety of different environments as you pursue your passion.
Keep reading to learn all about the computer numerical control industry, what CNC machinists do, CNC employment opportunities, average salary and more.
What is CNC Machining?
You might be asking yourself, “What does CNC stand for?”, and “What is a CNC machine?"
Computer numerical control (CNC) machining is a process in which pre-programmed computer software dictates the movement of factory tools and machinery.
This manufacturing process is used to control a wide variety of complex machinery, from mills and routers to grinders and lathes. For example, three-dimensional cutting can be completed with one set of prompts.
CNC machining makes it possible for a live operator to guide the commands of machining tools using buttons, levers and wheels. A common misconception is that CNC systems are similar to a regular set of computer components. However, CNC machining is unique in its software programs and consoles.
What Does a CNC Machinist Do?
CNC equipment cuts, drills and grinds into material with great precision as machinists adjust the machine to control speed, material feed and path of the cut. Machinists are responsible for ensuring machines are set up properly, running smoothly and creating quality product.
This often involves stocking their machines with needed materials and performing regular checks on output. They ensure the final product is free of defects and ready to move to the next step in the production process.
What Are CNC Machines Used For?
CNC machines are able to create complex parts rapidly with high levels of accuracy. Computerized processes convert designs into physical end products, which saves both money and time in the development process. Every finished part is identical, whether 10 or 10,000 of them are produced.
CNC machining plays an important role in the manufacturing process for many industries, including:
Aerospace
The aerospace industry requires great attention to detail, as engineers must precisely construct every component to avoid damage to the aircraft.
Devices in this industry encounter fast air currents, high speed and extreme pressures and it’s the job of a CNC machinist to ensure every part of the aircraft they work on meets high precision requirements.
CNC machining makes it possible to craft custom parts with precision and is also a great method for manufacturing and making tweaks to prototype parts.
Transportation
Creating automotive and diesel parts with CNC machining and testing makes it faster to create prototypes to exact specifications.
The transportation industry uses CNC machines to construct parts used on various vehicles, including passenger vehicles, transport trucks, freight trains, shipping vessels and more. CNC machines can create everything from brakes to engine parts.
Defense
Defense applications such as parts for tanks and communication equipment can be sourced from CNC machining suppliers. Similar to other industries, there is no room for error when it comes to these devices.
CNC machines conduct their own quality assurance, which ensures parts are reproduced identically, no matter how large the quantity.
Firearms
Accuracy and precision are also important when it comes to the manufacturing of firearms. For tracking purposes, for example, CNC machines record important information such as serial numbers on every part produced.
Commercial
CNC also plays an important role in the manufacturing of commercial products. In new product development, for example, the use of CNC machines can ensure there are no design flaws by producing a prototype that can be tested and approved before going into production.
Electronics
CNC machines can produce a wide variety of parts for the electronics industry. As technology advances, consumer electronics are becoming smaller yet more complex and powerful, which is where CNC machining comes in. CNC micromachining can handle specialized materials that meet specifications for even the smallest component.
Medical
From medical instruments to orthotics and surgical implants, CNC machines play an important role in the manufacturing of devices for the medical field. When a new product is developed, CNC machines’ fast prototyping capability can reduce the amount of time it takes to get to market.
Optical
CNC machining plays an important role in the optical industry, where multiple trials are performed in the product development phase. The use of CNC machines can shorten lead times and help with quality control to ensure profitability.
Oil & Gas
CNC machining can produce a variety of components used in the oil and gas industry, including parts for pipelines, refineries and rigs such as pins, rods, pistons, valves, cylinders and drill bits.
Marine Industry
CNC machining keeps the marine industry running by creating various elements of watercraft such as propellers, engine components, boat parts, prototype molds and insulating cases.

Machine operators produce machined parts by programming, setting up and operating CNC machines. Job duties typically include studying work orders, creating blueprints and engineering plans, doing stock inventory, programming and setting up mills and lathes, maintaining specifications in the production process, troubleshooting and keeping records.
Mill Machinist (advanced)
Mill machinists operate equipment such as milling machines, revolving lathe tools, drill presses and end mills to create manufacturing parts from metal, steel, plastic or aluminum.
They use provided blueprints to program machines to produce batches of parts that meet the outlined specifications. Mill machinists often work in the aerospace industry, which requires precision, attention to detail and a strong technical background.
Quality Control Inspector (advanced)
A quality control inspector analyzes products and materials, looking for defects that would result in parts not meeting specifications.
A typical day on the job may involve reading blueprints, monitoring operations, making adjustments to the production process, testing products once produced, sending products for repair and reporting data. A great inspector has an eye for detail and is able to spot defects that most people would miss.
Programmer (advanced)
A CNC programmer interprets project blueprints, designs programs and sets up machines to produce the component outlined in the program. Programmers complete test runs, and make tweaks and adjustments until the final product meets the specifications listed in the blueprint.
They are also often in charge of performing routine maintenance and cleaning to ensure machinery is functioning properly.
Mechanical Assembler (advanced)
Mechanical assemblers put together or fabricate mechanical parts, pieces and products. Using a variety of tools and equipment, they are responsible for ensuring required specifications are met and often work in a specific area of a production line in a manufacturing facility.
Duties and responsibilities often include following blueprints, maintaining inventory of product, performing quality checks, identifying product defects, repairing assembled equipment and following established safety procedures.
Design Engineer (advanced)
The role of a design engineer is to bring ideas to life by turning them into products. This career is great for someone who wants to combine creativity with their engineering knowledge.
These engineers work on a variety of products, from car engines to medical equipment to kitchen appliances. They’re responsible for ensuring the products they dream up will be cost-effective and efficient to produce.f
