In a method and a system for determining the feeding sped when bandsaw cutting a workpiece, the tough pitch TP of the bandsaw blade is determined in a first unit (6) depending on the shape and dimensions of the workpiece. In a second unit (12) feeding depth per tooth is determined depending on properties of the workpiece material and the width of the bandsaw blade. The bandsaw blade velocity BS is determined in a third unit (22) from the width W of the workpiece and the hardness of the workpiece material, whereafter the cutting time T is determined in a first calculating unit (30) from the height H of the workpiece, the feeding depth per tooth, the tooth pitch TP and the blade velocity BS. In a second calculating unit (32) the feeding speed MH for the bandsaw blade is then determined by the equation MH=H/T. A computer program, when executed on a computer, performs this determination of the feeding speed when cutting a workpiece with a bandsaw from supplied input data.
