The Analysis of Polishing Process of Cold Forging Die in Axial Symmetric Form and Axial Non-symmetric Form
In forging parts production, the die life is important for the production efficiency. If the die is fractured under production accidentally, it may cause a big damage to the productivity. One of die broken mode is a scratch on die surface caused by polishing in order to meet the design. It is for finishing the pre-mature die by polishing. It is required for more skillful craftspeople because the die life depends on damage of scratches. Therefore it is important to succeed their expertise constantly. It takes several years for craftspeople to be the expert on the job training. In this study, in order to accelerate their expertise transferring, we analyzed their expertise in focusing on quality of polishing in a forging part.
