Five-axis CNC machining technology introduction
Five-axis computer numerical control machining center refers to a high-speed computer numerical control machining center that integrates computer control, high-performance servo drive, precision machining technology and software technology, and expands five-axis linkage functions. Its system integration features can provide higher processing efficiency and processing capacity. The five-axis CNC machining center is in the X, Y, Z orthogonal three-axis drive system, and additionally installs a tilting and rotating two-axis rotation system, which are three linear axes (XYZ) and two rotary axes (AB) Or (AC), where the X, Y, and Z coordinates determine the tool position, and the rotation coordinates determine the tool direction. Different forms of five-axis CNC machine tools are used to meet the processing needs of many types of products. Although there are many brands and different shapes of five-axis CNC machining centers in the market, according to the different combinations of machine tool motion modes, there are mainly three types: spindle tilting type, table tilting type, and worktable/spindle tilting type. The structure of the machine tool with both rotation axes on the side of the spindle head is called the five-axis machine tool with tilting spindle, or the five-axis machine tool with double swing head structure. This kind of machine tool usually has the following three characteristics: The bearing capacity is strong and the size can be designed very large. ②It is suitable for processing large parts such as ship propellers, aircraft fuselage molds, and automobile panel molds. ③The rigidity and bearing capacity of the spindle are low, which is not conducive to heavy-duty cutting. The common structural forms are cross-type double swing head five-axis CNC machine tool structure (criss cross swing head form) and tool shaft drooping five-axis CNC machine tool structure (plumbing swing head type). The machine tool structure with two rotation axes on one side of the table is called a five-axis CNC machine tool with a tilting table, or a five-axis structure machine tool with a double turntable. The characteristics of this machine tool are usually: ①The main shaft structure is simple and the rigidity is relatively high. good. ②The manufacturing cost is low, and the C-axis rotary table can rotate without restriction, but because the worktable is the main rotary part, its size is limited. ③The carrying capacity is not large, so it is not suitable for processing oversized parts. Common structural forms include double turntable (cradle) structure five-axis CNC machine tools and B-axis vertical table five-axis CNC machine tools. The spindle head of the two rotation axes is set on the side of the tool axis, and the other rotation axis is on the side of the worktable, which is called the worktable/spindle inclined five-axis structure, or the swing head turntable five-axis structure. Its characteristics It is: the structural layout of the rotary axis is relatively flexible, and it can be any combination of two axes in the A/B/C three-axis. This structure combines the advantages of the spindle tilt and the worktable tilt, and the processing flexibility and bearing capacity are improved.
Application of five-axis technology in solid wood furniture

Compared with traditional machining methods, five-axis CNC machining equipment integrates technology, control, and calculation, reflecting the excellent advantages in precision, efficiency, and cost.
The processing of complex curved surfaces has unique advantages
For the carved patterns and curved surface solid wood furniture parts in solid wood furniture, it is difficult for ordinary three-axis CNC machine tools to complete continuous and smooth free-form surface processing in one clamping. During three-axis cutting, the working surface cannot flexibly change the angle according to the operation. When the workpiece to be cut is in a non-optimal state, the cutting tool is likely to leave hard machining marks on the surface of the test piece, such as the machining center point. The five-axis cutting can flexibly and quickly change the working surface while maintaining a good rotation speed in the cutting work of the tool, so as to ensure that the processing of the test piece is carried out at a uniform speed as much as possible, reduce the processing marks, and enhance the visual experience and texture of the workpiece surface.
