What's the Difference Between 3-axis, 4-axis & 5-axis Milling?
When designing a CNC-machined part, you may not initially consider which type of machine will be used. However, the machine type directly impacts the complexity of the geometry you can achieve. The key distinction between 3-axis, 4-axis, and 5-axis machining lies in the movement capabilities of both the workpiece and the cutting tool. As the number of axes increases, the machining process allows for greater flexibility and more intricate geometries. A higher-axis machine enables more precise cuts, reduces the need for repositioning, and allows for the creation of more complex parts in a single setup. 3-Axis Machining The most simple type of machining, where the workpiece is fixed in a single position. Movement of the spindle is available in the X, Y and Z linear directions. 3-axis machines are typically used for machining of 2D and 2.5D geometry. In 3-axis machining, all six sides of a part can be machined, but each side requires a se...
