What are the main factors affecting the cold work hardening of CNC parts processing

     In the process of processing, we usually encounter large and small problems. These are very common to us. When we encounter problems, we need to solve the problems instead of letting go, which will affect the cold work hardening of CNC parts. What is the main factor.

   Factors of the processed material: the hardness of the processed material is small, and the greater the plasticity, the more severe the cold work hardening.

   The shape factors of the tool: the rake angle of the cnc machining tool, the fillet of the cutting edge and the amount of wear behind the tool have a great influence on the cold work hardening layer. When the rake angle decreases and the amount of wear on the cutting edge and the back increases, the depth and hardness of the cold work hardened layer also increase.

   Cutting parameters of cnc parts processing: changes in cutting speed and feed have a greater impact on cold work hardening. When the cutting speed increases, the contact time between the tool and the precision part processing workpiece is short, the degree of plastic deformation is small, and the hardened layer and hardness are reduced. As the feed speed increases, the degree of plastic deformation increases and the degree of surface cold work hardening increases.
