The difference between 3 axis and 4 axis and 5 axis is in CNC machining

The main difference between 3-axis, 4-axis, and 5-axis CNC machining is the number of directions in which the cutting tool can move relative to the workpiece.

1、3-axis CNC machining: In 3-axis CNC machining, the cutting tool can move along three directions – X, Y, and Z – that are perpendicular to each other. This allows the cutting tool to create simple geometries and shapes, such as holes, slots, and flat surfaces. However, 3-axis CNC machining is limited in its ability to produce complex shapes and features, such as undercuts and angles.

2、4-axis CNC machining: In 4-axis CNC machining, the cutting tool can move along the same three directions as in 3-axis machining, but it can also rotate around a fourth axis – typically the A-axis or B-axis. This allows the cutting tool to reach areas of the workpiece that would be difficult or impossible to access with a 3-axis machine, such as angled holes and curved surfaces. 4-axis CNC machines are often used for producing parts with more complex shapes and geometries than those produced with 3-axis machines.

3、5-axis CNC machining: In 5-axis CNC machining, the cutting tool can move along the same three directions as in 3-axis machining, and it can also rotate around two additional axes – typically the A-axis and C-axis. This allows the cutting tool to reach every surface of the workpiece and create complex shapes and features with high accuracy and precision. 5-axis CNC machines are often used for producing parts and components for industries such as aerospace, automotive, and medical, where high precision and complex geometries are required.

Overall, the main difference between 3-axis, 4-axis, and 5-axis CNC machining is the level of complexity and precision they offer. 3-axis machines are suitable for simple geometries and shapes, while 4-axis and 5-axis machines are capable of producing more complex shapes and features with high precision and accuracy.
