Productive Laser Machining of Sintered Carbide Using a Combination of Nanosecond and Femtosecond Laser Ablation
Original language description
Short and ultrashort pulse lasers are increasingly used for cutting tool preparation. On the one hand, nanosecond lasers can ablate material very effectively but result in poor surface quality and material heat influence. On the other hand, femtosecond lasers are very precise tools with relatively low productivity. In this paper, a complex approach combining nanosecond laser roughing and femtosecond laser finishing is presented for effective sintered carbide ablation in one laser machine. The machining time was shortened by more than 74% in comparison to a femtosecond-only process. Surface roughness was decreased by more than 25% in comparison with roughness obtained after a nanosecond roughing approach. Complete removal of the heat affected zone was demonstrated by a SEM analysis of the cross-section images.
