Development of cutting tools with microscale .

01.07.2009 · We developed cutting tools with either microscale or nanoscale textures that improved the machinability of cutting processes. The cutting tools were successfully fabricated with a femtosecond laser. The textures enabled us to reduce the friction on the tool surfaces, decreasing the required cutting forces. This effect was mainly caused by the difference in the contact length between the tool ...
