Summary

We present a method to measure geometry and wear of cutting tools using an optical surface metrology device based on the focus variation technology. In order to measure the wear, the cutting tools are measured once before and once after usage. Afterwards, the two obtained 3D models are automatically registered to each other which allows us to calculate a difference height map from which the volume of the worn material is extracted. In addition to volume measurements, various other analysis methods such as form measurements of the cutting tool angle or its radius are presented.
