Abstract
There are various factors make some contributions to the cost estimation of stamping die for automobile sheet metal, including designing and manufacturing, management and sale. If a system can store the parameters and find the rule of estimating the cost of each process, it can reach the goal of convenient and efficient cost estimation which is a vital key to increase competition in this industrialized society.
In this research, the main goal is to establish the cost architectures and rules based on the design specifications, statistics and modified by collected knowledge from the experts. We use the CAD file of sheet metal and the process planning as the input, obtain the geometrical information of the sheet metal, the type of cam and the length of the knife, and calculate the cost of material, standard parts, milling, engraving, designing, trial plus indirect cost as the output.
The system provides the interface to modify the parameters concerning the cost estimation and in this way users can find the most suitable parameters to estimate the cost.
