| Summary: | The saving of leather, an extremely important objective in footwear manufacturing, requires following certains steps in the process of cutting the component parts of a footwear article in order to obtain better use of the leather surface. With this regard, the paper presents how to program the cuts of the outer parts of a shoe item in the cutting department, respectively a model of women shoes. For the chosen item, there were done single cuts for one number of size (10 options), as well as combined cuts of two distinct sizes (45 options).
Programming uppers cuts consists in their practical realization, followed by choosing the optimal cuts in order to obtain the best global utilisation index.
The value of the global utilisation index depends on the values of the utilisation indices of the simple and combined cutting ways, the programming strategy and the iteration mode of the cutting options.
By using the simple and combined cuts, for the developed program resulted a 72.04% global utilization index versus 70.64%, obtained by scheduling only single cuts, requiring a quantity of 91 hides. In the case of cuts options with higher utilisation indices, a judicious programming strategy can lead to an efficient cutting, close to the best automatic data processing program. |
