3D Milling – A Complete Guide
3D milling machines, also known as CNC machining centers, use computers to control the creation of complex parts from raw materials. These machines can perform advanced functions like contouring surfaces and drilling holes with extreme precision. This makes them indispensable tools in the manufacturing industry. They can create prototypes and reproduce specific parts of an object on a mass scale. In this article, we’ll explore the basics of 3D milling.
What is 3D CNC Milling?
Typically, CNC machines require 3 axes to accurately replicate an object. However, recent developments in software and machinery enable machines with 2 axes (2D) and even 1 axis (1D) to be effective CNC milling machines. This guide will cover the three types of 3D milling machines.
CNC milling is a subtractive process that removes material from a block to create an object. Essentially, it’s 3-dimensional carving. Machinists use computer programs called CAMs (Computer Aided Manufacturing). CAM communicates to a CNC machine where to mill and at what depth.

How Does 3D Milling Compare to Traditional Machining?
Three-dimensional milling machines offer numerous advantages over traditional machining methods. They excel at creating complex objects that other machines cannot produce. The machines utilize powerful rotating heads with various attachments and cutting tools, moving along X, Y, and Z axes to create objects from any angle.
A CNC milling machine uses computer-guided tools to cut through a wide range of materials, making it a versatile choice for manufacturers. For instance, companies like Parts Badger leverage these machines to create custom parts efficiently.
5 Ways in Which 3D Milling Differs from Laser Cutting Machines
3D milling machines operate on different principles than laser cutting machines, leading to distinct capabilities. Here are five key differences:
- Diameter: Laser cutters have a smaller diameter, limiting them to smaller pieces compared to 3D milling machines.
- Speed: Laser cutting machines are generally slower, while milling machines can handle multiple materials simultaneously.
- Durability: CNC milling machines can last for decades, whereas laser cutters may require servicing or replacement after five years.
- Dependence: The accuracy of laser cutters is software-dependent, while CNC milling relies on the machine’s precision.
- Number of Axes: Laser cutting machines typically operate on one axis, while CNC milling machines utilize multiple axes for deeper cuts.
Advantages of 3D Milling
3D milling machines provide several advantages over traditional 2D milling, including:
– Increased surface finish quality.
– Larger work envelope for bigger projects.
– More accurate forms and shapes.
– Faster processing times compared to CNC machining, while maintaining better accuracy than 2D drilling.
The 3D milling process involves moving a mill bit through the material while simultaneously rotating in X, Y, and Z directions, allowing for complex geometries to be cut from larger bulk materials.
