Abstract
A method and apparatus for controlling the feeding of a bandsaw blade in a horizontal bandsaw machine so that the bandsaw blade operates at a uniform optimum cutting rate. The cutting rate of the bandsaw blade is maintained constant by controlling the feeding speed of the blade into material being cut as a function of (1) the cross-sectional cut length at a time interval and (2) the feeding position of the bandsaw blade into the material.
