Embodiment Construction

[0030] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0031] The present invention is a five-axis CNC precision adjustment method, such as figure 1 , Figure 6 As shown, it includes the following steps:

[0032] Step 1: Fix the support frame 4 on the five-axis table 5. The function of the support frame 4 is to prevent the spindle 6 of the machine tool from interfering during processing, such as figure 2 As shown, the height Y1 of the support frame 4 must be greater than 1.5 times the radius Y2 of the main shaft 6 to prevent machining interference of the machine tool main shaft 6 and leave a safety gap. Then the two ends of a test workpiece (i.e. the shape before the base 3 is not processed) bottom are fixed on the support frame 4, so that the cutter 2 of the machine tool has good rigidity, firm and stable during processing, and the top of the test workpiece is a regular square pri...

Abstract

All surfaces are processed by the same machine tool coordinate system, a pedestal is processed to expose errors of a machine tool, and machine tool parameters are continuously compensated and regulated by pedestal processing, so that the ideal precision is reached. Compared with the prior art, the five-axis CNC precision regulating method has the advantages of combining the lowest cost with practical processing, so that practical precision which is consistent with practical processing can be calibrated; multiple five-axis CNC directions are verified and calibrated once, and precision obtainedby directly processing the pedestal through a five-axis CNC is directly equal to product processing precision, so that indirect errors are avoided, product processing precision is improved; and moreover, repeated use can be realized, so that the cost of enterprises is reduced.

Description

technical field [0001] The invention relates to a five-axis CNC precision adjustment method (five-axis numerical control machining center, hereinafter referred to as five-axis CNC), which is used for precision adjustment of various five-axis CNC machine tools for machining, and belongs to the technical field of five-axis CNC precision adjustment. Background technique [0002] With the development of high-end manufacturing industry, the demand for high-precision polyhedron parts is increasing for five-axis CNC, and the accuracy of five-axis machine tools is the most critical, and the accuracy of machine tools will be lost after a period of use. The traditional method is to calibrate and adjust the machine parameters through laser detection and other aspects to achieve the required theoretical accuracy, but the disadvantage is that the cost is high, and the calibrated accuracy will be different from the accuracy of the actual processed product. It is not easy to approach the ac...
