Experimental investigation of the parameters in deep drawing dies and estimation with fuzzy logic

In this study, drawing parameters in the deep drawing dies were experimentally examined. In the experimental studies, deep drawing process has been carried out on the different drawing parameters and on the different profiles as cylindrical and square. Experiments were carried out using Brass, DKP and Aluminium sheet metal materials. The drawing forces occurred during sheet metal deep drawing were measured by Baykon Load Cell. Effects of drawing parameters as die radius, punch radius, drawing speed, die clearance and sheet metal thickness on the drawing process were experimentally researched. Wrinkling, splitting, thinning of sheet metal thickness and the drawing force occurred during sheet metal deep drawing was investigated on the samples. It was show that the drawing parameters directly affected wrinkling, splitting, lower of sheet metal thickness and drawability rate. The samples with same drawing parameters were analysed on the finite element method by means of DYNAFORM and AUTOFORM software. It was seen that the results of the experimental study and the result of analysis are very close. According to the experimental results a fuzzy logic model was improved to estimate for effect of drawing parameters. Results introduce to literature for practically use.
