Study on Tool Setting Method of Micro-Milling Tool Based on in-Line Holography

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.
