    English: This article concerns characterizing and optimizing the process of water-jet engraving on stone materials through experimental analysis. The purpose is to find possible relationships between work parameters for an abrasive water-jet and the geometrical parameters created by grooves. Samples of White Carrara and Perlato of Coreno marbles were used in testing. An optical profilometer was used to measure the transversal profile of the groove, objectively characterized by a number of measurements described in the article, including two parameters of visual quality. Statistical analysis made it possible to indicate optimal settings to enter on the basis of desired results; for example, increases in width, depth or the degree of groove contrast. Italian: Questo articolo affronta la caratterizzazione e ottimizzazione del processo di incisione di materiali lapidei mediante water jet attraverso un’analisi sperimentale. La finalità è trovare possibili relazioni tra parametri impostati per la lavorazione, tramite idrogetto con abrasivo, e parametri geometrici ricavati dai solchi. Per questo studio sono stati analizzati dei campioni di marmo Bianco di Carrara e di Perlato di Coreno. Per mezzo di un profilometro ottico è stato possibile misurare il profilo trasversale del solco, caratterizzato in maniera oggettiva tramite alcune misure descritte nell’articolo, inclusi due parametri di qualità visiva. Attraverso un’analisi statistica è stato possibile indicare le impostazioni ottimali da settare in base al risultato desiderato: es. aumento della larghezza, profondità o livello di contrasto del solco

    Questo articolo affronta la caratterizzazione e ottimizzazione del processo di incisione di materiali lapidei tramite fascio laser attraverso un’analisi sperimentale. La finalità è trovare possibili relazioni tra parametri impostati per la lavorazione e parametri geometrici ricavati dai solchi.

English: This article deals with characterizing and optimizing the process of engraving stone materials with a laser beam through experimental testing. The purpose of testing was to find possible relations between the parameters set for work and the geometric parameters gotten from the grooves. For this study we tested samples of White Carrara marble. By means of an optical profilometer it was possible to measure the cross section of the groove, objectively characterized by a number of measurements described in the article including two parameters of visual quality. Through statistical analysis it was possible to indicate optimal settings to use on the basis of the results desired; for example, increasing the width, depth or contrast level of the groove

    Improved efficiency in manufacturing systems to achieve increased output and thus reduced production disturbances is a vital area. DES (Discrete-Event Simulation) can visualize and study the dynamic issues related to total efficiency in manufacturing systems. A methodology for investigating the production performance is presented. Increased performance of manufacturing systems means not only enhanced value for the company but in the long run for the society as a whole. Manufacturing companies are the basis of a country which many other activities rely on. A study on the behaviour of a manufacturing facility means, not only optimize the manufacturing process, but also understand the problematic about a particular production and thus, build better working conditions
