Shoe Last Grading and Experimental Estimation of Dimensional Variation Using Delcam CRISPIN 3D ? Last Maker

This article presets a study regarding dimensional changes of shoe lasts, using Delcam CRISPIN ? Last Maker, Grade function. The purpose is to obtain shoe lasts for inferior and superior size numbers to the one from the database obtained with ModelTracer and Last Maker software. Using the computer in last modelling activities enables an increase in performance for footwear producers by reducing the working time with testing the prototypes. Automatic grading provides the footwear producers with all size numbers of lasts that have to be produced. The presented studies ensure work accuracy and the application's utility for footwear manufacturers.
