Overview
What Is 5-Axis CNC Machining?
5-axis CNC machining combines three linear axes with two rotary axes, allowing the cutting tool or workpiece to be oriented from different directions.
For suitable designs this can improve access to multiple faces, angled holes and complex surfaces while reducing the number of separate setups. Fewer repositioning steps can also reduce setup-related alignment errors. Not every part requires 5-axis machining BoValley can review whether 3-axis, 4-axis, indexed 5-axis or simultaneous 5-axis machining is the most practical option.
5-axis machine configurations and benefits depend on whether the operation is indexed or simultaneous, the machine architecture and the part geometry.

The Process
How Does 5-Axis CNC Machining Work?
Review CAD files and technical requirements, select suitable machining strategies, manufacture complex components, and inspect critical features to meet drawing specifications.
The advantages
- Complex Geometry:• Supports suitable parts with angled faces and compound surfaces.
- Multi-Face Access:• Reach multiple faces with fewer separate setups when geometry permits.
- Contoured Surfaces:• Useful for suitable sculpted surfaces and complex toolpaths.
The challenges
- Angled Features:• Supports selected angled holes and non-orthogonal features.
- Reduced Repositioning:• Fewer setups may help reduce alignment variation and handling time.
