The five-axis linkage machining center technology refers to a complex shape of the surface needs to use five independent axes *** with the same CNC interpolation movement in order to obtain a smooth and smooth shape of the processing technology. Although theoretically speaking any complex surface can be used X, Y, Z three-axis coordinates to express, but the actual machining tool is not a point, but a certain size of the entity, in order to avoid the space distortion of the surface of the processing of the tool and machining the surface of the interference between the surface and to ensure the consistency of the cutting conditions of the surface of the various points, the need to adjust the tool axis and the surface of the surface of the normal vector between the angle between the two-dimensional direction.
The number of axes in a five-axis machining center refers to the number of axes that need to move independently when machining the same surface, not the number of controllable axes that the CNC has. For example, the gantry milling machine in order to ensure the parallelism of the crossbeam lifting and lowering, you need to synchronize the movement of the left and right two drive axes W1, W2, that is, W1 as the active axis, and make the W2 axis to keep in sync with it. Therefore, they can only be used as one independent movement axis. In addition, if the complex sculpture surface has a rotary body feature, it does not need Y-axis motion, which can be realized on a CNC lathe or turning center.
Five-axis machining center processing a wide range of conventional three-axis can not be processed or difficult to process parts, and five-axis machining center involves a wide range of industries, mainly involved in the industry of aviation, aerospace, military, scientific research, high-precision medical equipment and high-precision molds and other national importance of the industry, it can be seen that five-axis machining centers have a pivotal role in the industry of the country's importance. Influence. Five-axis machining centers can process a variety of complex curved surfaces or shaped parts, such as: turbine engine blades, aircraft engine propellers, marine propellers and other complex curved surfaces and shaped parts. General purchase of five-axis machining centers customers are required to process more complex shapes of parts, will not be used to process simple plane and simple surface parts, the use of five-axis machining centers to process plane parts, it is really too big to use.
