The fitness movement of each ordinate can be completed by the operation table and the movement of the CNC tool, but the orientation is defined by the movement orientation of the CNC tool relative to the product workpiece. Generally, five-axis linkage refers to the linear tool radius compensation movement of five random coordinates in x, y, z, A, B, and C.

In other words, the five-axis refers to the three moving axes of x, y, and z plus two random axes of rotation. Compared with the general three-axis (x, y, z three controllability) machining, five-axis machining means that when machining parts with very complex geometric shapes, it is necessary to process CNC blades, which can be in five playability. Carry out precise positioning and connection.

The CNC lathe selected for five-axis machining is generally called a five-axis CNC lathe or a five-axis machining management center. Five-axis machining is common in the aerospace industry, processing body parts with random slopes, turbine engine parts, and centrifugal impellers.
