The increase in demand for industrial automation in the manufacturing industry has exposed the significance of machine vision in quality inspection and process monitoring. Contrast to stylus instruments, the computer vision systems have the advantages of being non-contact. In the present study a novel technique has been reviewed to explore various applications of Image processing in inspection of cutting tool surfaces. Measurement and inspection of Surface roughness, Tool wear, Tool profile, Thickness of coating done on tool and Surface defects are all reviewed in this paper which will help in developing a specialized inspection system particularly for inspection of machining tools alone in reduced production cost and minimised time.
