✦ Synopsis

Residual membrane stresses are induced in wide bandsaw plates by cold-rolling longitudinal tracks, a process known as roll-tensioning. When properly done, roll-tensioning substantially improves the cutting performance of the bandsaw. However, excessive rolling can buckle the plate causing rubbing of the plate against the work piece. The analysis in this paper shows that excessive roll-tensioning induces transverse or torsional buckling of the plate, depending on the location of the longitudinal tracks across the plate width and the magnitude of the uniform longitudinal (axial) tension applied to the plate during the cutting operation. The buckling modes are characterized by a number of waves along the length of the plate that are qualitatively predictable by theory.
