What is CNC milling?
CNC milling (full name: Computer Numerical Control Milling) is a process that uses computer controls and rotating cutting tools to produce custom precision engineered parts or items. It is commonly associated with materials such as metal, plastic, and wood.
The process involves using these computer controls to operate machining tools to shape and cut materials to precise specifications to create custom precision engineered products. It is a very popular method because it can create fine sizes and shapes.
The machine receives instructions from a design that is input through a CAD program. The machine then mounts the correct tool and holds the material in place. Finally, the tool rotates at thousands of revolutions per minute and moves with the workpiece to contact different parts of the design.
Benefits and Features of CNC Milling
- High Precision and Accuracy: CNC milling machines are able to produce parts with extremely high precision and accuracy, which is critical to industries such as aerospace, medical, and automotive.
- Flexibility and Versatility: CNC milling machines can be programmed to produce a wide range of parts, from simple to complex designs. This flexibility enables manufacturers to produce custom parts to meet specific requirements.
- Create Angled Shapes: CNC milling is ideal for creating angular shapes, flat surfaces, grooves and channels, holes, curves, chamfers, and many other features.
- Cost Savings: CNC milling machines can provide significant cost savings. Increased efficiency and precision can reduce waste and scrap, while the ability to produce complex parts can eliminate the need for multiple machines or additional machining steps.
Differences between CNC Milling and CNC Turning
There are distinct differences between CNC milling and CNC turning. CNC milling uses a cutting tool that moves along a stationary workpiece to remove raw material. During CNC turning, the workpiece rotates while the cutting tool moves along the material to create the shape. CNC turning is suitable for projects that require cylindrical parts. CNC milling should be used for parts that do not require cylindrical shapes and can be used as a secondary finishing operation to add definition. Complex parts that require prismatic and cylindrical features can use a combination of milling and turning.
