Description

technical field [0001] The invention relates to the field of machine tool detection, in particular to a digital detection method and device for the geometric accuracy of a machine tool. Background technique [0002] Geometric accuracy is the basis of machine tool accuracy. Only a machine tool with good geometric accuracy can achieve good performance and high precision. Therefore, in the process of machine tool manufacturing, each geometric accuracy of the machine tool needs to be strictly tested to ensure the accuracy of the test results. At present, the detection method of the geometric accuracy of the machine tool mostly adopts the manual recording method of mechanical dial gauge measurement, which requires repeated manual adjustment and recording during the detection process, which not only requires a high level of skill of the operator, but also the detection process is complicated and the efficiency is low; in addition , The detection data is also processed manually.
