Abstract: | This paper presents a model for predicting the cutting forces for waved-edge milling cutters that are widely used in rough
machining. The development of the model is based on the analysis of the complicated cutting edge of waved-edge cutter. According
to the existing local cutting force model and from the relationship of local cutting force and chip load, local cutting force
can be derived. Then the model is obtained by dividing the cutter into a number of differential elements in the axial direction
and summarising the resultant cutting force produced by each differential cutter disc engaged in the cut. A numerical algorithm
is introduced for the calculation of total force and the calibration of the relevant parameters in the model. A series of
experiments under different cutting conditions are conducted to confirm the validity of the developed model. The agreement
between the experimental and simulative results is satisfactory, which shows that the model is effective for cutting force
prediction in end milling with waved-edge cutters.
