Damage Detection of Coated Milling Tools Using Images Captured by Cylindrical Shaped Enclosure Measurement Setup.

Currently, only two direct automatic tool damage detection systems are available in the tool resharpening industries of German market. Both systems work on the principle of laser-optical 3D detection. By means of non-contact laser scanning, 3D models of the scan object are created which are then compared with digitally stored original model of the tools through a software. Damage images are created based on detected deviations. However, these systems have the major decisive disadvantage that they require about 15 to 20 min for a complete detection of a tool and are quite expensive, ranging between 100,000-400,000 Euros. Therefore, there is a scope of technically and economically optimized tool quality inspection system. The main goal of this work is to develop a new method by which the damages of different coated tools are identified with reduced cost and without compromising the accuracy of the damage.
