3D cutting tool-wear monitoring in the process
Luka Čerče,Franci Pušavec,Janez Kopač 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.9
The tool-wear of cutting tools has a very strong impact on the product quality as well as efficiency of the machining processes. Therefore,it in-the process characterization is crucial. This paper presents an innovative and reliable direct measuring procedure for measuringspatial cutting tool-wear with usage of laser profile sensor. The technique provides possibility for determination of 3D wear profiles, asadvantage to currently used 2D techniques. The influence of the orientation of measurement head on the accuracy and the amount ofcaptured reliable data was examined and the optimal setup of the measuring system was defined. Further, a special clamping system wasdesigned to mount the measurement device on the machine tool turret. To test the measurement system, tool-life experiment was performed. Additionally, a new tool-life criterion was developed, including spatial characteristics of the tool-wear. The results showed thatnovel tool-wear and tool-life diagnostic represent objective and robust estimator of the machining process. Additionally, such automationof tool-wear diagnostics on machine tool provides higher productivity and quality of the machining process.
