In order to predict machining forces it is necessary to know the chip volume and calculate the specific cutting force of the process, the prediction force problem is concerned on the right formulation of this last parameter that most models considers constant. This paper analyzes the behavior of the specific cutting pressures on end milling by calculating, from experimental data force, the pressure on each moment of cut. This procedure involves an approach which do not considers the force on each cutting edge piece but a function of area and height of cutting. After the cutting pressure analysis, some comparisons with previously published experiments are done and it can be seen that for the prediction of end milling cutting forces, the variation in time of the specific cutting force should be considered.
