Abstract In view of the shortcomings of the existing tool setting methods, we proposed a new method of tool setting for micro-milling tools based on in-line holographic imaging. After researching and analyzing the holographic imaging principle and key problems of holographic image, a set of digital holographic tool setting prototype was built, and the micro-milling tools was measured on a five-axis machining center using a standard tool. The experimental results show that, the holographic tool setting prototype can effectively realize the detection of micro-milling tools, and the relative accuracy of this instrument is 5.1μm. Under the same detection conditions, compared with the measurement results of a high-precision external presetter, the relative error of the tool setting instrument is 0.033%, while the relative error of the holographic tool setting prototype is 0.007%, and it can effectively realize the detection of micro-milling tool. This results verify that holographic imaging method can be used for the high-precision tool setting of micro-milling tools.
