High speed threading of inclusion-modified steels with Feb 15, 1999 · Table 8 and Fig. 7 illustrate the relationship between the recorded cutting forces, the tool life and the hardness values of the threaded surfaces of the 708M40T steel at a feed rate of 0.40 mm rev 1 and at various cutting speeds. The increase in cutting forces noted at higher cutting speeds can be associated with the reduction in tool life obtained.
