Method of cutting with a band saw

A method of cutting a workpiece with a band saw machine having a blade comprising:

• rotating, with a motor assembly of the band saw machine, the blade about a central longitudinal axis;
• moving, with the band saw machine, at least one of the blade and a workpiece rectilinearly along the central longitudinal axis relative to the other during said rotating to form a cut in the workpiece;
• supporting a back edge of the blade at one of a first position before a lateral entry position of the cut and a second position after a lateral exit position of the cut, during said rotating, with a first back support member;
• extending, during said rotating and said moving, a first extension arm of the first back support member and thereby shifting the back edge of the blade at the one of the first position and the second position a first distance rectilinearly along the central longitudinal axis toward the workpiece, wherein said shifting is cumulative to rectilinear movement from said moving;
• supporting at least one lateral side edge of the blade with a first lateral side support;
• sensing, with at least one sensor embedded in one of the back support and the first lateral side support, a level of force acting on the blade;
• and
• changing, with a controller, a frequency of pulsations of said shifting in response to the level of force sensed by the at least one sensor during said sensing.
