Abstract
This research aimed to apply the transfer die technology together with the forming simulation by using finite element method to assist the analysis and the design of a high-precision continuous forming die for the panel auto part forming, which was made from 1.4 mm thick steel JFS A3001. The outcome of the finite element simulation of a specimen could be applied in forming a specimen without any specimen damage. Therefore, the high-precision continuous forming die was designed based on the results and factors from the forming simulation. After the design, the high-precision continuous forming die was manufactured and the specimen stamping test was conducted to satisfy the customer’s specifications. The results from the testing shown that the specimens obtained from the forming process are similar to the sample provided from the customer. Only minor forming die modification was required. In addition, the results of specimens inspection according to the inspection location using measuring tools shown that the size and the circumference of the specimens were in an acceptable range with more than 0.05 significance level of P-value (P-Value >α) and 95% statistical confidence level. As a result, die manufacturers can effectively save time, reduce cost and minimize risk occurred from errors in the die manufacturing.
