The authors discuss a novel approach to estimation of individual tooth runout in milling. The approach is based upon a simplified linear force model and leads to good results at high values of immersion. Two variants of the approach for estimating runout are presented. The first method utilizes torque while the second considers in plane force components as indicators of runout. Simulations are used to verify the equations that were derived for relating runout to in plane forces and to allow the assessment of the influence of the spacing of the discrete force samples on accuracy. Experimental evidence validates the approach for a wide range of immersion values. Experiments also show that the approach is able to identify edge breakage in the presence of significant initial runout.
