The swarf formed during the cutting process will have a higher hardness and a significantly lower plasticity and toughness due to the relatively large plastic deformation. This phenomenon is called cold work hardening. After cold hardening, the swarf ....
Whether the tool swarf breaking is reliable or not has a major impact on normal production and operator safety. In the cutting process, the swarf of the swarf will splash and hurt people, and it is easy to damage the machine tool; Long strips of swarf....
