PREDICTION OF CUTTING FORCES IN THE DRY MACHINING OF LIGHTS ALLOYS.

This paper analyses the relationship between the cutting forces and length, according to experimental results obtained in lights alloys, in particular UNS A97050-T7, UNS A92024-T3, during the dry drilling. The tests have been performed with several cutting speed, 83 m/min, 60 m/min and 50 m/min. Box-Cox transformations have allowed finding a fitted model and determining a significant relationship between maximum cutting forces, for each hole, and cutting length. Thus, it is possible to establish prediction limits for new observations of cutting forces, at 95% confidence level. [ABSTRACT FROM AUTHOR]
