Laser micro processing of carbide tool insert

Abstract

For a number of applications there is evidence that the tribological conditions for mating surfaces can be improved by surface texturing. Literature shows that texturing the tool rake face can have a positive influence on tribological properties. This research focuses of the texturing of tool rake surface by laser machining. Compared to other texturing techniques, laser provides the flexibility of machining customized textures on tool surface. This paper deals with the assessment and optimization of the process parameters for generation of textures on cemented carbide inserts under ambient conditions by using a femtosecond laser. The paper is a significant contribution to the efficient and rapid generation of customized surface texture on hard tool inserts.
