CNC Milling: Breakdown of the Basics
What is CNC milling?
CNC milling is a subtractive manufacturing process that uses computer numerically controlled (CNC) machines to remove material from a solid block to create a desired shape. A rotating cutting tool is used to precisely remove material according to a pre-programmed design.
CNC milling vs. turning: What are the differences?
Both CNC milling and turning are CNC machining processes, but they differ in how the material is moved. In CNC milling, the cutting tool moves around a stationary workpiece. In CNC turning, the workpiece rotates while the cutting tool remains stationary. Milling is suitable for creating complex shapes, while turning is ideal for creating cylindrical or hollow parts.

CNC Milling: Factors to Consider
If you're looking to outsource CNC milling for your project, here are some factors to consider:
- Complexity of your part: Simpler parts can be machined on basic 3-axis machines, while intricate designs may require a multi-axis machine.)
- Material: Different materials require specific tooling and expertise.
- Tolerance requirements: The level of precision needed for your parts will influence the machine and expertise required.
- Volume: Production volume will impact the choice of CNC milling machine and overall cost.
