The present work shows empirical models to foresee the cutting forces developed during stone lapping. The developed empirical model puts into relationship the cutting force and energy with the relevant cutting parameters, such as the depth of cut and the feed rate, for the stone known as Coreno Perlato Royal. The cutting force and energy have been modelled as a function of material removal rate by a simple linear relationship. The developed models may be used to guide the selection of cutting conditions. The chip generation and removal process has been quantified in order to assist both the toolmaker and the stonemason in optimising the tool composition and cutting process parameters, respectively.
