SUMMARY
The calculation of total percent cold work (CW) for a plate that has undergone multiple cold-working processes is determined using the formula %CW = (Ao - Ad) / Ao x 100. In this discussion, the initial thickness (Ao) is derived from the first cold work at 50 mm, and the final thickness after further cold work is 33 mm. The correct calculation yields a total percent cold work of 47.2%. It is essential to maintain proper parentheses in the formula to avoid calculation errors.
