Influence of chip breaker geometries on chip breaking behaviour during profile grooving

authored by: Berend Denkena, Benjamin Bergmann, Marita Murrenhoff
Abstract: Chip breakers are used in turning to improve chip breakage. In standard cutting inserts, they are pressed into the rake face before sintering. However, for specialized tools like profile grooving tools, this pressing is not possible. Instead, a laser preparation process can be applied after grinding the tool profile to create a diverse range of chip breaker geometries. The aim of this investigation is to gain insights into the relationship between the geometric parameters of laser-prepared chip breaker geometries and chip formation. For this reason, experimental turning investigations were conducted with varied chip breaker geometries. Based on these experiments, chip formation was observed for different profile geometries and chip breakers. The findings indicate that the inlet angle, outlet angle, width, depth, and lateral ridges significantly influence chip-breaking behaviour. These results can inform the development of application-specific design for chip breaker geometries.
