To truly understand five-axis machining, we must first understand what a five-axis machine tool is. Five-axis machine tool (5 Axis Machining), as the name suggests, refers to adding two rotary axes to the three common linear axes of X, Y, and Z. The two rotation axes in the A, B, and C three-axis have different motion modes to meet the technical requirements of various products.

In terms of the mechanical design of the 5-axis machining center, machine tool manufacturers have always been unremittingly committed to developing new motion modes to meet various requirements. Based on the various types of five-axis machine tools currently on the market, although there are various types of mechanical structures, there are mainly the following types:

1. Two rotation coordinates directly control the direction of the tool axis (double swing head form).

2. The two coordinate axes are at the top of the tool, but the rotation axis is not perpendicular to the linear axis (sagging head type).

3. The two rotation coordinates directly control the rotation of the space (double turntable form).

4. The two coordinate axes are on the table, but the rotation axis is not perpendicular to the linear axis (plumbed table type).

5. One of the two rotation coordinates acts on the tool, and the other acts on the workpiece (one pendulum and one revolution).

After seeing the five-axis machine tools with these structures, I believe that everyone should understand what and how the five-axis machine tools are moving.
