Method of cutting with a band saw

A method of cutting a workpiece (18, 54) with a band saw includes rotating, with a band saw machine, a blade (10) about a central longitudinal axis (56). The method also includes supporting a back edge (44) of the blade (10) with first and second back support members (76), each operable to generate...

Zusammenfassung:	A method of cutting a workpiece (18, 54) with a band saw includes rotating, with a band saw machine, a blade (10) about a central longitudinal axis (56). The method also includes supporting a back edge (44) of the blade (10) with first and second back support members (76), each operable to generate respective levels of force against the back edge (44). The method also includes monitoring, with sensors (64), respective levels of force exerted against the first and second back support members (76) by the back edge (44). The method also includes moving the blade (10) and a workpiece (18, 54) closer to one another along the central longitudinal axis (56) closer during the rotating. The method also includes dynamically controlling the first and second back support members (76) to generate different levels of force during the moving and the rotating.
