Debugging method of engraving and milling machine tool

The invention provides a debugging method of an engraving and milling machine tool, which comprises the following steps that a processing test is carried out on a test piece through the engraving and milling machine tool, and the test piece comprises a test body and a test curved surface arranged on the surface of the test body; debugging the engraving and milling machine tool based on the machining effect of the engraving and milling machine tool on the test piece in the machining test; the processing test comprises at least one of the following test items: a three-axis reverse mark test, a sharp corner position precision test, a reversing vibration test, a parallel connection equal-height processing test, a straight line to arc and arc connection straight line test, and a 3D tool mark entering test. Compared with the prior art, the debugging method of the engraving and milling machine tool has the advantages that the performance of the engraving and milling machine tool is judged based on the real machining
