Before the 5-axis milling tool path design, the system accuracy of the CAD 3D model should be set as high as possible. Especially when model conversion between different CAD systems, CATIA (*.model) format and Parasolid (*.x_t) format are preferred for data conversion. Secondly, use IGES format for data conversion. When using the IGES format, the system accuracy should generally not be less than 0.01mm. Especially when performing five-axis high-speed cutting of precision parts, the accuracy of the model and the accuracy of tool interpolation have an important impact on the output of the tool path.

With the increase of complex surface design of parts in modern industry, 5-Eksen işleme, CNC işlemenin giderek artan bir bölümünü oluşturacak. As 5-axis CNC machining adds two degrees of freedom of rotation, it increases the difficulty of CNC machining motion simulation calculation and tool interference check, özellikle son derece karmaşık şekillere sahip parçaları işlerken.

Milling can obtain a good curved approximate surface. When using a ball-end tool for three-axis milling, the linear feed motion in the x, y, and z directions can ensure that the tool cuts to any coordinate point on the workpiece, but the direction of the tool axis cannot be changed. The actual cutting speed of the point on the tool axis is zero, and the chip space in the center of the tool is also very small. If these points are involved in cutting, the unfavorable cutting conditions will cause the quality of the machined surface to decrease, the blade wear will increase, and the machining time will be prolonged. So that high-grade tool materials are not fully utilized.
