Simultaneous 5 Axis Machining vs. 3+2 Machining: How to Choose
Simultaneous 5-axis CNC machining and 3+2 machining use the same five machine axes, but they differ in how those axes move during cutting and which parts they are best suited for.
Simultaneous 5-Axis Machining
3+2 Axis Machining
Axis Motion
All five axes can move together during machining. As the tool follows the programmed path, the rotary and linear axes continuously coordinate to change the cutting position and orientation. This allows the machine to follow complex surfaces and contours without repeatedly stopping to reposition the workpiece.
Three linear axes perform the cutting from a fixed indexed angle. The two rotary axes first rotate the part or tool into the required position and then remain stationary during the cut. When another side or angle needs to be machined, the rotary axes index to a new position before cutting continues.
Part Geometry
Best suited for complex contours, deep cavities, impellers, and freeform surfaces that require continuous multi-axis tool movement.
Well suited for multi-face parts, angled holes, pockets, and features that can be machined from several indexed positions.
Setup Requirements
More features can often be completed in a single setup, reducing repositioning and helping maintain consistency between machined features.
Several indexed positions may be required to complete the part, depending on the number and orientation of features.
Surface Finish
Continuous tool motion is better suited to smooth transitions and complex curved surfaces with fewer visible tool marks.
Suitable for standard machined surfaces, but complex contours may require additional finishing or repositioning.
Best For
Ideal for high-complexity parts where geometry, surface continuity, and fewer setups are priorities.
A practical choice for multi-angle parts that do not require continuous five-axis motion.
Types of 5 Axis CNC Machine Configurations
5-axis CNC machines use different rotary-axis configurations depending on part size, geometry, tool access, and machining requirements. Two common designs are trunnion-style and swivel-head configurations.
Trunnion-Style 5-Axis Machine
Swivel-Rotate-Style 5-Axis Machine
Workpiece Movement
Rotary table tilts and rotates the workpiece during positioning and machining.
Workpiece remains more stable while the spindle tilts or rotates around the part.
Axis Configuration
Typically combines tilting and rotary table axes.
Typically combines a tilting spindle head with a rotary axis.
Tool Access
Strong access to multiple sides of small and medium-sized parts.
Greater flexibility around large, deep, or irregular components.
Tool Length
Longer tools may be required for some deep or restricted features.
Flexible spindle orientation can allow shorter and more rigid cutting tools.
Part Type

Common Five Axis Machining FAQs
A: 5-axis CNC machining is an advanced machining process that uses three linear axes (X, Y, and Z) combined with two rotary axes to control the cutting tool or workpiece position. Unlike traditional 3-axis machining, it allows the tool to approach parts from multiple angles, reducing the need for repeated setups. This makes it suitable for producing complex components with curved surfaces, angled features, deep cavities, and tight precision requirements.
A: 5-axis CNC machining works by coordinating five controlled movements simultaneously or positioning two rotary axes before cutting to achieve the required machining angle. The X, Y, and Z axes control linear movement, while the additional A, B, or C rotary axes adjust tool orientation or workpiece rotation. This enables better tool access, shorter setups, and more efficient machining of complex geometries.
A: The main difference between 5-axis and 3-axis machining is the number of controlled movements available during cutting. A 3-axis CNC machine moves along the X, Y, and Z axes, making it suitable for standard parts with flat surfaces, holes, and pockets. A 5-axis machine adds two rotary axes, allowing machining from multiple angles and improving efficiency for complex parts with advanced geometries.
A: The difference between simultaneous 5-axis and 3+2 machining is how the rotary axes move during the cutting process. Simultaneous 5-axis machining allows all five axes to move continuously together, making it ideal for complex contours, freeform surfaces, and highly detailed components. In 3+2 machining, the rotary axes position the part at a fixed angle before cutting, which is often more suitable for angled features and multi-sided machining.
A: 5-axis machining is suitable for complex precision parts that require multiple machining directions, curved surfaces, or difficult-to-reach features. Common applications include aerospace components, medical devices, automotive parts, semiconductor components, impellers, molds, and precision housings. By reducing setups and improving tool accessibility, 5-axis machining helps maintain accuracy while manufacturing complex geometries.
A：5-axis CNC machining can process a wide range of metals and engineering plastics, including aluminum, stainless steel, titanium, brass, copper, PEEK, and other machinable materials. Material selection depends on the required strength, weight, corrosion resistance, thermal performance, and application requirements. With proper tooling and process planning, 5-axis machining can produce precision components across industries such as aerospace, medical, automotive, and industrial equipment.
