An analysis of specific cutting pressure in end milling process is presented. To model analytically milling forces it is necessary to compute the chip volume and the specific cutting pressure. The problem is concerned on the exact geometrical formulation of the process and especially on the last parameter. Considering only the influence of shearing and friction on the rake face and not taking into consideration the effects on cutting of the flank face i.e. the edge effects, the results obtained shown an error proportional to the contribution of the tool contact with the finished surface. This work aims taking the value, or the variation, of specific pressure from experimental data considering both effects, cutting force and edge force. This procedure analyzes the influence of the specific force modelling on the cutting process.
