In the process of machining, there are many factors that can affect the cold work hardening of CNC parts. There are not only one but also many kinds. When we encounter problems, we need to find out the causes to solve them. So the machining of CNC parts is the same. So what are the main reasons that affect the cold work hardening of CNC parts?
- Processed data elements: the hardness of processed data is small, and the greater the plasticity, the more serious the cold work hardening level is.
- Tool shape elements: CNC machining tool front angle, edge fillet and tool back wear have a great impact on the cold work hardening layer. The depth and hardness of the hardened layer increase with the decrease of the rake angle and the increase of the wear loss of the edge and back.

- Cutting parameters of CNC parts: the change of cutting speed and feed rate has great influence on cold work hardening. When the cutting speed increases, the contact time between the tool and the workpiece is short, the plastic deformation level is small, and the hardening layer and hardness are reduced. With the increase of feed rate, the plastic deformation level and the surface cold work hardening level increase.
