The present work shows a study on cutting of stone by diamond tool. The diamond grits on the tool surface remove material through the scratching and the cracking of the stone volume. This work reports a kinematics analysis between a single grit of a diamond tool and the stone volume. In previous works, a mathematical relationship of the chipping geometry, due to a single grit, with machining and tool parameters has been derived. This work aims to measure the cutting force due to a single tool grit for different machining conditions. In particular, the machining conditions that are most interesting by an industrial point of view have been investigated. The stone cutting force has been measured by a Kistler 9257 BA piezoelectric platform dynamometer. The outputs of the dynamometer were fed into an A/D converter and sampled at high frequency by a PC. Then, the signals recorded by the PC were filtered by Matlab software at a low frequency. The collected data have been put into relationship with machining and tool parameters.

Abstract
The present work shows a study on cutting of stone by diamond tool. The diamond grits on the tool surface remove material through the scratching and the cracking of the stone volume. This work reports a kinematics analysis between a single grit of a diamond tool and the stone volume. In previous works, a mathematical relationship of the chipping geometry, due to a single grit, with machining and tool parameters has been derived. This work aims to measure the cutting force due to a single tool grit for different machining conditions. In particular, the machining conditions that are most interesting by an industrial point of view have been investigated. The stone cutting force has been measured by a Kistler 9257 BA piezoelectric platform dynamometer. The outputs of the dynamometer were fed into an A/D converter and sampled at high frequency by a PC. Then, the signals recorded by the PC were filtered by Matlab software at a low frequency. The collected data have been put into relationship with machining and tool parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
