One experiment consisted of successive milling passes on two inclined surfaces of 215mm length (see Fig. 2), interrupting the process at regular intervals to measure tool flank wear. The experi- ments continued up to the moment when the tool reached the end of its life. Each experiment was carried out in triplicate.
