The DHardTools project aims at the development of carbide tools with functional diamond coatings for micromachining of ultra-hard materials. The development of this product presents as an innovation the possibility to extend the field of application of diamond coated tools and the monitoring of the micromachining process.
For this purpose the introduction of boron into the diamond structure will be investigated to increase the toughness and process a temperature sensor. The control of the micromachining process through temperature monitoring will increase the lifetime of precision diamond coated tools. On the other hand, these tools can be used for micromachining without the use of lubricant in order to be economically and environmentally more viable.
