Fast Minute: Comparing 3-axis and 5-axis CNC machining

Table of Contents

Part geometry, target cost-per-part, and other factors contribute to decisions about how to best make your part. In our latest Fast Minute video, Digital Sales Manager Gabe Smith runs through the differences between 3-axis and 5-axis machining and when to use each type of CNC machining.

Customers ask all the time if 3-axis or 5-axis machining is best for their project. Let’s break it down.

 

With 3-axis machining, the tool cuts along the X,Y, and Z axes. It can refer to turning — where the workpiece rotates and a lathe shapes the components, or milling — where a rotating cutting tool removes the material from the workpiece in linear directions.

 

If you only need to cut a flat surface, a 3-axis machine is the way to go. They’re less expensive and require less prep time.

 

With 5-axis machines, the tool moves along the X, Y, and Z axes and rotates around the A and B axes. This lets operators approach a part from all directions without having to reposition the workpiece between operations.

 

5-axis machining will give higher yields and greater accuracy. But 5-axis machining is more expensive because of the specialized equipment and need for expert machinists.

 

Still not sure if 3-axis or 5-axis machining is right for your project? We’re here to help.
