Abstract
This article compares the machining forces of face milling processes using two different tool holders with the same carbide insert: a regular feed rate holder with cutting angle of 45o and a tool holder with high feed using 15o. For comparison, a design of experiments with the same cutting speed, chip load area, maximum chip thickness and, consequently, different advances is carried out. During the machining of titanium alloy Ti6Al4V the machining forces and the angular position of the tool are collected. The model used for shear force prediction considers the contribution of the chip load area and the cutting edge length. Tool wear is measured to confirm if it can be neglected in the model. The comparison suggests that the position angle had no impact on the force model and is economically advantageous by reducing the machining time with the same chip removal rate.
