Simultaneous 5-axis machining involves the cutting tool moving along five axes simultaneously, while 3+2 axis machining involves the cutting tool moving along three axes while the workpiece is tilted along two additional axes.
Simultaneous 5-axis machining and 3+2 axis machining are two different strategies used in 5-axis CNC machining, each with its own advantages and applications. Let’s explore the key differences between these two machining techniques:
Simultaneous 5-Axis Machining:
- In simultaneous 5-axis machining, the cutting tool can move along all five axes (X, Y, Z, A, and B) simultaneously during the machining process.
- This means the tool can approach the workpiece from any angle and orientation, allowing for continuous and smooth tool paths, especially when machining complex 3D geometries and sculptured surfaces.
- Simultaneous 5-axis machining is ideal for parts with intricate curves, undercuts, and compound angles, as it can efficiently machine these features without the need for multiple setups or repositioning the workpiece.
- The ability to machine complex parts in one setup improves accuracy and reduces cycle times, making it suitable for industries like aerospace, automotive, and medical where high-precision components are required.
3+2 Axis Machining:
- 3+2 axis machining, also known as positional 5-axis machining, is a technique where the cutting tool is limited to three linear axes (X, Y, and Z) for the main cutting motion, while the remaining two rotational axes (A and B) are locked or fixed at specific angles.
- The tool is repositioned and locked into a new orientation at each step or “index” before the cutting process starts, effectively machining the part from different directions but not moving all axes simultaneously during cutting.
- While 3+2 axis machining cannot follow complex tool paths like simultaneous 5-axis machining, it allows for more stable cutting conditions as the tool is only cutting along three linear axes at a time.
- 3+2 axis machining is suitable for parts with features that can be accessed from specific angles without the need for complex tool movements. It is often used for roughing, finishing, and secondary operations on parts that don’t require full 5-axis simultaneous motion.
