Learn about CNC machining
What is CNC machining?
CNC machining is a process in which computer programs control the movement of factory tools and machinery. The process is used to create precision parts through subtractive manufacturing, which involves cutting material from a solid block to achieve the desired shape. The four main types of CNC machining processes include milling, turning, drilling and electrical discharge machining (EDM).
Basic knowledge: How CNC machining works
CNC machining begins with a digital 3D design, typically created using CAD (computer-aided design) software. Once the design is complete, it is converted into a CNC program using CAM (computer-aided manufacturing) software. The program is fed into the CNC machine, which interprets the commands and controls the tools to create the part.
Step by step process:
design creation: CAD software creates detailed digital representations of parts.
program conversion: CAD files are translated into G-code, a language that the CNC machine understands.
set up: The CNC machine is ready, including loading the material and holding it securely.
processing: CNC machines execute programs to carve parts using tools such as drills and milling machines.
- finishing: After machining, parts may require additional finishing processes such as grinding, polishing or coating to improve surface quality.
Types of CNC machine tools
CNC machining consists of a variety of machines, each designed for a specific application:
- CNC milling machine: Use a rotary cutting tool to remove material from a block. Great for complex geometries.
- CNC lathe: Rotates the workpiece by means of a fixed cutting tool, making it ideal for cylindrical parts.
- CNC milling machine: Effective for cutting softer materials such as wood and plastic.
- CNC plasma cutting machine: Use a plasma torch to cut conductive materials.
- CNC laser: Uses a focused laser beam to cut or engrave materials with high precision.
