AN EMPIRICAL RELATIONSHIP BETWEEN CUTTING FORCES AND LENGTH IN DRY DRILLING IN ALUMINIUM ALLOYS

This paper analyses the relationship between the cutting forces and length, according to experimental results obtained in aluminium alloys, in particular UNS A97050-T7, UNS A92024-T3, during the dry drilling. Box-Cox transformations have allowed finding a fitted model and determining a significant relationship between maximum cutting forces and cutting length, for each hole. Thus, it is possible to establish prediction limits for new observations of cutting forces.
