The universal machinability index and the prediction of machine tool stability

Abstract In a recent publication, on the dynamic cutting of metals, Das and Tobias [7] derive expressions for the change in the cutting forces, under vibratory cutting conditions. The use of these for the prediction of machine tool stability is compared with the use of the incremental cutting force equation proposed by Tobias and Fishwick [1], and which has been used with some success in a number of cases.
