What Exactly is a CNC Machine?

A CNC machine is a computer-controlled manufacturing device that interprets coded instructions to precisely cut, carve, or shape materials. These machines can handle various materials such as metal, plastic, wood, and even ceramics. The instructions are typically written in G-code, a programming language that tells the machine how to move, how fast to move, and what tools to use.

How Do CNC Machines Work?

The process begins with a CAD (Computer-Aided Design) file, which contains the blueprint of the part or object. This file is converted into machine-readable code using CAM (Computer-Aided Manufacturing) software. The CNC machine then executes the code to produce the desired object with unparalleled precision and consistency.
