Özet
The Parabolic Blending (PB) technique has been widely used in various research fields, such as rotor noise prediction, over the last few decades. However, in the literature, PB is not utilised for the thickness prediction of thermoformed products. In this study, Polystyrene (PS) sheets of various thicknesses were thermoformed using a lab-scale thermoforming machine. Firstly, thickness distributions in thermoformed PS products were obtained by the experimental method. Then, PB was used to estimate the thickness distribution of conical semi-finished thermoformed parts. The obtained results were then compared with the ones obtained experimentally. A comparison reveals that the use of PB provides more accurate thickness values than the experimental results. As a result, PB can be utilised for the prediction of thickness distribution in thermoformed products which have been formed by the same mould.
