Multi-axis Tutorial

This tutorial introduces multi-axis machining techniques (4 and 5 axes) in CNC Simulator Pro.

Axis Configuration

In addition to the three linear axes (X, Y, Z), multi-axis machines include:

• 4th Axis (A or B): Rotation around X or Y
• 5th Axis (C): Rotation around Z

Example: 4th Axis Machining

Simultaneous 5-Axis Machining

In simultaneous 5-axis machining, all axes move together to maintain optimal tool orientation relative to the surface.

Advantages

• Access to complex geometries
• Better surface finish
• Reduced setups
• Shorter tools = greater rigidity
