What Does CNC Mean in Manufacturing

Students peering into CNC machine

In the fast-paced manufacturing world, CNC has set a new standard and expanded the possibilities. This automated manufacturing process uses computer software to control and operate machinery, such as mills, lathes, grinders, and laser cutters. It is used in the automotive, aerospace, construction, electronics, medical, and many other industries, and its uses continue to evolve.

What does CNC mean in manufacturing?

CNC stands for Computer Numerical Control. If you hear “CNC” in a manufacturing environment, it means that a computer rather than a human directs a machine. People still need to program and oversee the machine, but generally, CNC reduces the need for human oversight.

CNC machining has many benefits, including:

  • Accuracy: CNC machining is precise and eliminates human error. This is especially important in fields such as aerospace and medicine, where precision is critical.
  • Efficiency: Machines can operate 24/7, thereby increasing production. They also perform tasks quickly, which speeds up production time.
  • Cost-efficiency: CNC machines produce less waste and require fewer operators. 
  • Versatility: It is possible to manufacture a wide variety of items using CNC, and it is easy to change what item is being manufactured.
  • Repeatability: Once a CNC machine is programmed, it can consistently produce parts and products, removing the variability and human error that often occurs with manual manufacturing processes.

What can you do with a CNC machine?

The possibilities of what you can do with a CNC machine are virtually endless. For example, what does a CNC router do? Using pre-programmed directions, it cuts, carves, and engraves complex and precise shapes in wood, glass, plastic, metal, or foam. 

To do this, the machine first needs a CAD drawing to be translated into computer code by a programmer. This acts as the CNC machine’s instructions. The machine can then follow these instructions with precision, efficiency, accuracy, and repeatability.

Mills, lathes, routers, and plasma cutters are some of the most common types of CNC machines and are frequently used in the manufacturing of:

  • Turbine blades
  • Car door panels and fendersTurbine blades, car prototypes, furniture, jewelry, medical prosthetics
  • Electrical components
  • Engine mounts
  • Furniture
  • Medical implants
  • Jewelry
  • Circuit boards

CNC machining is only growing in popularity, and its use continues to expand, making it a great potential career path.

What are some career options related to CNC?

Careers in CNC machining are varied and require different levels of skill and expertise. A CNC programmer designs and writes the programs that allow CNC machines to create specific parts or products. A CNC setup technician then prepares the machines by installing tools and fixtures as needed and sets up the machine by loading the programs it needs to operate. A CNC machinist (also called a CNC operator) sets up and runs CNC machines, monitors the process, and performs quality control checks.

At IYRS, you’ll learn from outstanding instructors like David Riley who holds a BFA in Furniture Design from Rhode Island School of Design. Prior to IYRS, David spent more than ten years in professional fabrication, design, and prototyping. David's approach to teaching is thoughtful, proactive, and focused on measurable, positive student outcomes. His professional background and deep skillset are invaluable for preparing students for exciting, hands-on careers in modern manufacturing.
