Choosing 3-axis CNC machining, 4-axis CNC machining or 5-axis CNC machining for your project comes with understanding a thing or two. The three important things you must consider when choosing:
1. Your Budget
On the budget scale, 5-axis is more costly than 4-axis, which is also more costly than 3-axis. The reason is the increase in capability, functions, and features as you move from 3 to 4 to 5.
2. Your Requirements
For complex parts, you should go for the 5-axis CNC machining. However, for projects aimed at producing small and simple parts, 3-axis and 4-axis are ideal.
3. Operating Procedures
The higher you go in terms of axis number, the complex it is to operate. In situations that warrant an easy operating procedure, 3-axis is the simplest, followed by 4-axis CNC machining.
