The increasing request, both in industrial field and in urbanistic furniture, of complex-shaped products in natural stone makes necessary the use of flexible and completely automatic machines, such as NC machining centres.

The aim of this work is to characterise the wear of the diamond mills by variables that are easy to measure, and effective to describe wear mechanism. An optic microscope and an electronic balance have allowed both to observe the mill shape and to measure the diameter and weight changes of the mill after consecutive machining steps. An original test protocol has been developed to carry out all experimental tests. The results show how a set of variables, that are related to the macro-geometry of the diamond mill and are called macro-geometric wear variables, may be used to foresee the tool wear in a synergic way and, therefore, to improve usage of the tool.

Abstract
The increasing request, both in industrial field and in urbanistic furniture, of complex-shaped products in natural stone makes necessary the use of flexible and completely automatic machines, such as NC machining centres. These machines mainly use versatile tools such as synthesised diamond mills. The aim of this work is to characterise the wear of the diamond mills by variables that are easy to measure, and effective to describe wear mechanism. An optic microscope and an electronic balance have allowed both to observe the mill shape and to measure the diameter and weight changes of the mill after consecutive machining steps. An original test protocol has been developed to carry out all experimental tests. The results show how a set of variables, that are related to the macro-geometry of the diamond mill and are called macro-geometric wear variables, may be used to foresee the tool wear in a synergic way and, therefore, to improve usage of the tool.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
