Patent ID: 7654180

Claim:
Method for cutting a workpiece with a bandsaw, wherein the tooth pitch TP of the bandsaw blade is determined depending on the shape and dimensions of the workpiece, in that feeding per tooth is determined depending on workpiece material properties and shape and size of the workpiece as well as the saw blade width, in that the bandsaw blade velocity BS is determined from the width and material hardness of the workpiece material, whereafter a cutting time T is determined from the height H of the workpiece, the feeding per tooth, the hardness of the workpiece material, the tooth pitch and the bandsaw blade velocity BS, and in that the feeding speed MH of the bandsaw blade is then determined by the equation MH=H/T characterized by the cutting time T being determined by the equation: T=H·K 2 ·K 1 /(39.7 S·HF·TP·BS ) where the tooth pitch TP is stated as tooth per inch, K 1 is a tooth pitch factor, K 2 is an empirically determined factor for compensation for different values of the bandsaw width, and S is the nominal feed per tooth.
