Comparative study in the passive force and cutting torque in the milling process of polymer matrix composites and aluminum alloys

This paper presents the results of a study undertaken to investigate the passive force and cutting torque during the milling of carbon fiber reinforced plastics saturated with epoxy resin and two aluminum alloys: AlSi21CuNi (AK 20) and 7075 (PA 9). The milling process was conducted using end mills with diamond inserts. The machining parameters were changed equally for each material as a result of which the passive force and cutting torque during the milling of these materials could be compared.
