Abstract
In a method and a system for determining the feeding speed when bandsaw cutting a workpiece, the tooth pitch TP of the bandsaw blade is determined in a first unit depending on the shape and dimensions of the workpiece. In a second unit 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 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 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 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.
