What does CNC manufacturing stand for?

The term “CNC” stands for Computer Numerical Control, which means machines are driven by computer programming instead of manual operation.

What does CNC Manufacturing mean? What is CNC manufacturing?

CNC manufacturing refers to a type of manufacturing that uses computers to control a machine in order to create parts and components. CNC machines create precision components for various industries, such as automotive, aerospace, medical devices, and electronics.

What is the difference between subtractive vs. additive manufacturing?

The difference between subtractive and additive manufacturing is the way material is handled.

Subtractive Manufacturing

In subtractive manufacturing, material is removed from a block of material to create a component. Some examples of subtractive manufacturing include:

·        CNC machines (mills & lathes)

·        Laser cutters

·        Water jet cutters

·        EDM (Electrical Discharge Machining)

Additive Manufacturing

In additive manufacturing, material is added layer by layer to make components. With additive manufacturing complex shapes can be made that are not feasible with subtractive manufacturing. Some examples of additive manufacturing include:

·        3D printing

·        Stereolithography

·        Laser powder bed fusion

·        Directed energy deposition
