what's different 4 axis cnc and 5 axis cnc router  

4-axis CNC ROUTER

Building upon the constraints of the 3-axis method delineated earlier, gained prominence alongside 5-axis CNC machining. The 4-axis CNC machining process maintains the same operational principles but integrates an additional axis.

This supplementary axis introduces rotation along the X-axis, designated as the A-axis or B axis . While the spindle retains its three linear axes of movement (X-Y-Z), akin to 3-axis machining, the A-axis facilitates rotation of the workpiece. Various configurations exist for 4-axis machines, with the prevalent type being 'vertical machining,' where the spindle rotates about the Z-axis. The workpiece is affixed along the X-axis and can rotate alongside the fixture on the A-axis. With a single fixture setup, machining can be executed on four sides of the component.

There exist two primary classifications of 5-axis CNC machines: 3+2 machines and fully continuous 5-axis machines.

In 3+2 axis machining, two rotational axes function independently of each other. This allows for the workpiece to be rotated to various compound angles concerning the cutting tool for machining features. However, simultaneous rotation of both axes during machining is not feasible. Despite this limitation, 3+2 machining is adept at fabricating highly intricate 3D shapes.

On the other hand, fully continuous 5-axis machining enables simultaneous rotation of both rotational axes while machining, with the cutting tool moving linearly in XYZ coordinates. This method can manufacture exceedingly intricate 3D shapes, encompassing not only planar compound-angled features but also intricate curved surfaces. Consequently, it grants the capability to produce components typically reserved for molding processes.
