Determination of the Optimal Blank Diameter in the Case of Mini Deep Drawing by Applying the Fuzzy Logic and Taguchi Methods

Article Preview

Abstract:

An important problem in obtaining mini drawn parts with high precision is represented by the blank geometry. Utilization of a blank with optimal shape and dimensions leads to the following benefits: improves the accuracy of the drawn parts and determine the costs reduction due to reduced material consumption and cost, lower number of technologic operations, shorter manufacturing times etc. An adequate blank prevents the following effects on drawn part: avoids the part fracture, conducts to a uniform distribution of the material thickness in drawn part and reduces the blank holder force required by the drawing process. The present paper analyses the results of investigations made by simulation and experiment concerning the establishment of the optimal blank diameter in the case of mini cylindrical drawn parts made from aluminium sheets. The optimal blank diameter was determined by applying the Fuzzy Logic and Taguchi methods.
