Description
technical field [0001] The invention relates to a detection device and a detection method, in particular to a rotation angle precision detection device and method based on a laser detection system. Background technique [0002] With the development of technology and the increasing demand for flexible processing and small batch processing of complex workpieces, multi-axis machine tools, especially five-axis CNC machine tools, are becoming more and more popular. Compared with the three-axis machine tool, the five-axis machine tool has two additional rotation axes, so it has many advantages that cannot be compared with the ordinary three-axis machine tool. The clamping error of the workpiece, and the processing tool can be processed from the optimal angle, reducing the cutting force and improving the tool life, thus greatly improving the processing efficiency and tool life, and the five-axis linkage machining center can complete products that cannot be processed by other machin...
