Abstract
Careful experiments have shown that the tangential component of the cutting force (FT) in metalcutting is approximately proportional to the frontal area of the uncut chip. The constant of proportionality is material specific and is typically called the specific power (Ks). If the cutting force were available during production, it would be possible to detect tool wear, broken teeth, contact between the tool and workpiece and easy to determine Ks for a new material. The cutting force is usually measured a short distance from the cutting zone, using a cutting force dynamometer. The ceramic pieces exhibit the piezoelectric effect, which means that, as they are deformed, they produce an electric charge that can be amplified into a voltage proportional to the force that caused the deformation. The cutting force between the tool and the workpiece causes small motions of the top plate relative to the bottom plate.
