Summary The band saw blade vibration under non-moving and moving conditions has been experimentally studied for band saw blades unfitted with saw tension and back crown, fitted only with saw tension, and only with back crown. The lateral natural frequency of a band saw blade was found to decrease by fitting saw tension in a saw blade, but there was little or no effect for blades having only back crown. The torsional natural frequency of a band saw blade increased by fitting saw tension in a saw blade, but again there was little or no effect of fitting back crown in a blade. The lateral natural frequency decreased by tilting the upper wheel for the band saw blades investigated. On the contrary, when the upper wheel was tilted the torsional natural frequency increased for an untensioned blade with no back crown, and blades fitted only with back crown, however, there was little or no effect for a band saw blade fitted only with tension. The lateral and torsional natural frequencies significantly affected the over all self-excited displacement vibration of band saw blades. However, the displacement vibration due to the frequency of the number of wheel rotation affected significantly the over all self-excited displacement vibration of a band saw blade fitted with excessive back crown.
