[0002] In the manufacturing and machining process, the chip-breaking performance of cutting tools is crucial. To ensure that the chips meet controllable requirements, researchers have designed chip breaker structures and analyzed chip breakage mechanisms and chip trajectory patterns to solve the chip breakage problem.

[0003] Existing chip-breaking inserts still present challenges in chip breaking for difficult-to-machine materials. During machining, chips tend to entangle on the workpiece or tool surface, leading to decreased machining quality, reduced efficiency, shortened tool life, and even threats to personal safety.

[0004] Furthermore, surface roughness is a key indicator for measuring the microscopic geometric errors of a machined part's surface and an important factor in evaluating the surface quality of the part. The geometry of the cutting tool directly affects the cutting force and contact area, thus affecting the surface roughness. However, existing tool geometries make it difficult to achieve the required surface roughness when machining parts.

[0005] To address this, a three-edged, fully circular arc-shaped chip breaker groove indexable tool is proposed. Utility Model Content
