2. What is Multi-Axis CNC Machining?

**Multi-axis CNC machining** refers to the use of computer numerical control (CNC) machines that are capable of moving and cutting along multiple axes simultaneously. Unlike traditional **two-axis machines**, which can only move in two dimensions (X and Y), multi-axis machines can typically operate in three or more dimensions, allowing for **complex geometries** and **detailed designs** to be achieved with ease.
Multi-axis machining commonly involves three, four, five, or even more axes. The most widely used configurations include:
- **Three-Axis Machining**: Movement along the X, Y, and Z axes. Most basic CNC machines fall into this category.
- **Four-Axis Machining**: Adds a rotational axis, allowing for more complex shapes without needing to reposition the workpiece.
- **Five-Axis Machining**: Integrates additional rotational axes, providing exceptional flexibility and precision for intricate designs.
