Background
The five-axis linkage machining center has the characteristics of high efficiency and high precision, and the workpiece can be machined by one-time clamping. If the five-axis linkage high-grade numerical control system is matched, the complex space curved surface can be processed with high precision, and the method can be more suitable for processing modern dies such as automobile parts, airplane structural parts and the like. The rotary shaft of the vertical five-axis machining center is two modes, one is a workbench rotary shaft, and a workbench arranged on a lathe bed can rotate around an X axis, which is defined as an A axis, and the general working range of the A axis is +30 degrees to-120 degrees. The middle of the workbench is also provided with a rotary table which rotates around the Z axis at the illustrated position, which is defined as a C axis, and the C axis rotates 360 degrees. Therefore, through the combination of the A shaft and the C shaft, the five surfaces of the workpiece fixed on the workbench except the bottom surface can be processed by the vertical main shaft, and the five-shaft linkage machine tool is used, so that the clamping of the workpiece is easy. During processing, a special clamp is not needed, so that the cost of the clamp is reduced, multiple clamping is avoided, and the processing precision of the die is improved. The five-axis technology is adopted to process the die, so that the number of the used clamps can be reduced. In addition, in the five-axis linkage NC program, the cutter length compensation function is still effective, the cutter radius compensation is invalid, when the cylindrical milling cutter is used for contact forming milling, different programs are required to be compiled for cutters with different diameters, the cutter radius compensation cannot be completed by the CNC system which is popular at present, because enough data are not provided in the ISO file to recalculate the cutter position, when a user carries out numerical control processing, the precise size of the cutter needs to be frequently replaced or adjusted, and the cutter track is sent back to the CAM system to recalculate according to the normal processing program, so that the whole processing process rate is quite low.
