The so-called five axis machining refers to having at least five coordinate axes (three linear coordinates and two rotational coordinates) on a machine tool, and being able to coordinate motion for machining simultaneously under the control of CNC machining. Compared with general three-axis linkage CNC machining, this type of CNC machining has the following advantages:
1. It can process continuous and smooth free-form surfaces that cannot be processed by general three-axis or are difficult to complete in one clamping. For example, blades of aircraft engines and steam turbines, propellers used in ships, as well as many shells and molds with special surfaces and complex cavities and hole positions, if using ordinary three-axis CNC, due to the fact that the pose angle of the cutting tool relative to the workpiece cannot be changed during the machining process, interference or under machining (i.e. cannot be machined) may occur when machining certain complex free-form surfaces. When using a five axis linkage machine tool for machining, the pose angle of the tool/workpiece can be adjusted at any time during the machining process, which can avoid interference between the tool and workpiece and complete all machining in one clamping;

2. CNC machining can improve the machining accuracy, quality, and efficiency of spatial free-form surfaces. For example, when machining complex surfaces with three-axis machine tools, ball end mills are often used. Ball end mills are formed by point contact, which has low cutting efficiency. Moreover, the tool/workpiece pose angle cannot be adjusted during the machining process. It is generally difficult to ensure that the optimal cutting point on the ball end mill (i.e. the point with the highest linear velocity on the ball end) is used for cutting, and there may be situations where the cutting point falls on the rotation center line where the linear velocity on the ball end mill is equal to zero. By using a five axis machine tool for machining, due to the adjustable tool/workpiece pose angle, not only can this situation be avoided, but also the optimal cutting point of the tool can be fully utilized for cutting at all times, or a spiral end mill formed by line contact can be used instead of a ball end mill formed by point contact. Even by further optimizing the tool/workpiece pose angle for milling, higher cutting speed and cutting line width can be obtained, resulting in higher cutting efficiency and better machining surface quality.

3. The advantages of mold processing. In traditional mold processing, vertical machining centers are generally used to complete the milling of workpieces. With the continuous development of mold manufacturing technology, some weaknesses of vertical machining centers have become increasingly apparent. Modern mold processing commonly uses ball end milling cutters, which bring significant benefits in mold processing. However, if a vertical machining center is used, the linear velocity of its bottom surface is zero, resulting in poor smoothness of the bottom surface. If four or five axis linkage machine tool processing technology is used to process molds, the above shortcomings can be overcome. Using a five axis linkage machine tool to process molds can quickly complete mold processing, deliver quickly, better ensure the quality of mold processing, make mold processing easier, and make mold modification easier.
