What’s the Benefit?

Five-axis machining improves cycle times and precision by enabling work on multiple surfaces within the same setup.

The flexibility granted by multiple approach angles opens up opportunities for shorter tools. Getting close to the workpiece can improve machining accuracy, surface quality, metal removal rates and cutting speeds. Tools can also use standard shapes for tapered surfaces, eliminating the need for separate tooling. Improved part access not only makes keeping an eye on the part easier for operators, but also simplifies verification. Operators can use rotary motion to true fixtures.

Programming has also come a long way since the early days of five-axis machining. Modern CAD/CAM systems use five-axis programming that is similar to three-axis programming.

What To Watch For?

Troubleshooting can initially be more difficult for five-axis machining, but the increased flexibility of five-axis machining means adjusting toolpaths to avoid problems is much simpler. Coolant drainage and foaming still depends on the machine design and the chemical formation of the coolant.
