METHOD AND DEVICE FOR CONTROLLING THE FEED SPEED OF CIRCULAR SAW BLADES

Abstract

The invention relates to a method and device for controlling the feed rate (v) of a saw blade which is provided with teeth and rotates about a centre point relative to a workpiece during a machining process. According to the invention, during a rotation of the saw blade about the centre point, the feed rate (v) is selected differently during a machining process effected by teeth of different sectors (S) of the saw blade, wherein the feed rate (v) is selected to be lower during a machining process effected by teeth of sectors (S1) having larger radial spacing of the teeth from the centre point than during a machining process effected by teeth of sectors (S2) having smaller radial spacing of the teeth from the centre point. In this way, the operation of the saw blade can be optimised and the service life can be increased.
