✦ Synopsis

The wide bandsaw plate is often initially stressed by "roll-tensioning" to improve cutting performance. Despite the critical importance of this process to practice, a quantitative understanding of the relationship between the "roll-tensioning" and the plate performance improvement is not available principally because the residual stresses generated in the roll-tensioning process are unknown. This paper predicts the approximate residual stress state induced in the bandsaw plate by the longitudinal plastic deformation generated by "roll-tensioning", given the number and location of each rolling track and the magnitude of longitudinal plastic strain in each rolling track. In the case of incremental indentation of the plate by rolling with spherical rollers, the longitudinal plastic deformation in each track, and consequently the residual stress state of the plate can be predicted by measuring the indentation profile of each rolling track.
